5 bf1systems DigiTyre II User Guide -.doc Page 5 of 48 4 Quick Start Guide When you receive your delivery of Tyre Pressure & Temperature Monitoring System components, this will include the wheel sensors corresponding to the system you ordered, and the valves to mount these to your wheel rims. The installation instructions for the valves and sensors can be found in section 12 of this document. Once the TPMS ECU and the other system components are installed in the vehicle (the guidelines for installing these components can be found in section 7 of this document) and connected by the TPMS wiring harness, the TPMS PC software (supplied on a CD or via ) will need to be installed. The PC software is required to communicate with the TPMS ECU. The TPMS ECU can use a RS232 or a CAN connection depending on the ECU. Since some modern laptops don t have a native RS232 port, it may be necessary to use an USB to RS232 converter. If sourcing an USB to RS232 converter bf1systems recommend one based on a FTDI chip. Alternatively bf1systems hold stock of these and can supply them alongside the TPMS. For CAN connections both Vector and Peak Systems hardware are supported. Once there is a suitable RS232 cable, plug the laptop into the car s RS232 connection on the wiring loom, power up the TPMS ECU and run the DigiTyre PC software. The software should connect to the TPMS ECU and display Connected in the bottom status bar. If it does not say this, it may be necessary to change the communication port that the software is trying to use for accessing the RS232. The user will need to determine what port number the RS232 port (or USB port) is via device manager, then in the DigiTyre software, browse to Comms Setup, and select from the drop down list the number of the communication port the software should use. Once configured press the Connect button to connect to the ECU, the TPMS ECU should now say Connected in the bottom status bar. Figure 1 Status bar when successfully connected Once the PC software is connected, the TPMS ECU requires two files to be loaded in to the ECU A permit list (Encrypted file of the wheel sensor IDs provided on a CD or via with the sensors) A Configuration File (Internal ECU settings and CAN bus setup; this will be supplied by a bf1 technical representative) The permit list is an encrypted list of the sensor serial numbers; this list must be loaded into the ECU to allow it to receive those TPMS sensors. This stops other teams receiving wheel sensor data which are not their own. To select the list that is required, go to the Update Permit List page in DigiTyre II, then click Load File and select the.pmt file which was supplied. After selecting and opening the file, the list of sensors will need to be loaded into the ECU by pressing on Update Device button. The list will now be loaded into the TPMS ECU. After loading in the permit list, a configuration file has to be loaded into the TPMS ECU. This file defines the behaviour of the system and which CAN IDs the ECU will be transmitting and receiving on. To load this file in, navigate to the Motorsport Configuration page, then press the Load Config File button. Select the configuration that was supplied by the bf1 technical representative, then press the Write Config button to load it into the ECU. Please ensure that this step is carried out as it can easily be missed. The ECU configuration will take a few seconds to be loaded in the ECU. After this has completed its operation, power cycle the ECU. For the TPMS to operate fully we suggest that the car speed is transmitted to the ECU via the CAN. This is in order for the ECU to understand when it is moving on track and lock on to the active wheels attached to the car. Provided with the ECU will be a simple CAN database for the default messages sent by the default configuration. The team can change the CAN IDs according to their setup, a bf1 technical representative can assist with this. We also recommend that Atmospheric pressure and Atmospheric temperature signals are also sent to the TPMS ECU if possible. These signals are less crucial but allows the system to give more accurate data when at altitude.

6 bf1systems DigiTyre II User Guide -.doc Page 6 of 48 After this is all completed, navigate to the Live Update page within the bf1systems PC software. The pressures/temperatures from any installed wheels containing TPMS sensors and the three messages (CarSpeed/CarAtmosPres/CarAtmosTemp) will be displayed. There is a choice for Gauge pressure to be displayed on the Live Update page (this is done by selecting the Settings option at the top of the page, then clicking Gauge Pressure) however this will not change the CAN output, this is simply a visual change in the software. You can also choose your preferred units for tyre pressure (psi or bar) and temperature ( C or F).

7 bf1systems DigiTyre II User Guide -.doc Page 7 of 48 5 Overview The bf1systems Tyre Pressure Monitoring System (TPMS) consists of; 433MHz Wheel sensor Motorsport Valve (specified for each customers rim detail) Digital Antenna or LF Trigger Antennas ECU Wiring Harness (not provided as standard) PC Software with corresponding licence dongle DigiTyre has been specifically developed to meet demanding applications where the vehicle and support team require fast and accurate tyre pressure and temperature data from their wheel electronics. To achieve this, bf1systems have developed the wheel electronics to be even more intelligent to their surroundings this has been achieved by utilising bi-directional RF / LF functionality and an on board accelerometer. The wheel electronics contain a battery, absolute pressure sensor, temperature sensor, accelerometer, micro controller, radio frequency (RF) transmitter, low frequency (LF) receiver and a Infra-Red element (only present on Single Point and Array sensors) all housed in a very compact and robust wheel housing. The wheel electronics may be mounted either onto the rear of a bf1systems valve, or onto the wheel rim itself by means of a custom housing. Utilising the valve mounted option results in a very straightforward installation, with no need for rim modifications. Where the use of the valve mounted arrangement is not practical, due to rim / tyre geometry a custom housing/valve assembly can be designed.. The bf1systems TPMS sensors transmit data at different rates depending on the environmental conditions. We therefore recommend that all sensor are deflated between events in order to preserve the battery life. Mode Pressure (BarGauge) Roll switch Transmission Rate Storage < < 30kph No Transmission Stationary > < 30kph Every 255 seconds Quiet < < 30kph No Transmission Moving > > 30kph Every 1 second Table 1: Sensor transmission modes bf1systems offer two types of TPMS depending on the application. Positioned System Learning System You will find more information on each system below.

8 bf1systems DigiTyre II User Guide -.doc Page 8 of Positioned TPMS The bf1systems positioned Tyre Pressure Monitoring System (TPMS) is suited for all open wheel formula cars. In order to operate the positioned TPMS the user must manually allocate a wheel sensor IDs (laser engraved on each unit) to positions on the car (FL/FR/RL/RR). When the car detects it is moving (via the CAN) it detects which of the wheels are fitted to the car and locks onto these IDs. When the car enters the pits the system will release the sensor IDs and looks for the next set. Positioned systems are typically used on lightweight open wheel race cars where wheel arches are not present or weight is a significant factor. 5.2 LF Learning TPMS The bf1systems LF learning TPMS provides teams with a fit and forget Tyre Pressure Monitoring System (TPMS) due to its ability to automatically learn the wheel sensors fitted to the car, and start monitoring them, without the user having to manually allocate sensors to specific corners. The learning system consists of four Low Frequency (LF) Trigger Antenna units, one of which is located in each wheel arch. The LF Trigger Antenna broadcasts a request signal over a range of approximately one metre, and any wheel sensor within that vicinity responds by transmitting a Radio Frequency (RF) datagram back to unit. This is referred to as triggering the sensor.. The ECU utilises this communication with the sensor to determine which sensorid is fitted to which position on the car. When the car is stationary the antennas periodically request datagrams from the wheel sensors to ensure live data is available. When the vehicle starts moving, the system conducts a check of the wheels it has learned by using the accelerometer inside the wheel sensors to filter out any non-moving wheels (e.g. spare wheels fitted to the car), and learns only a complete set of moving sensors. When the wheels on the car are changed, the system will automatically learn the new sensors fitted to the car, and will start monitoring these, meaning no user interaction is required. Learning systems are used on all vehicles where the trigger can be mounted into the wheel arch correctly. For example LMP1/LMP2/GT3 vehicles.

9 bf1systems DigiTyre II User Guide -.doc Page 9 of 48 6 System Components 6.1 Wheel Sensor Each sensor contains a battery, radio frequency (RF) transmitter, low frequency (LF) receiver, absolute pressure sensor, temperature sensor, and an accelerometer. The LF receiver enables the unit to respond to external commands issued by diagnostics tools and or LF Triggers. The accelerometer is used to detect when the wheel is rotating, enabling the moving transmit mode. The wheel sensors are contained in a Peek (450GL30) housing and are designed to function in the harsh environments common in motorsport. Multiple sensor types are available; Lite TPMS 25.0mbar Resolution 0.33Hz Transmission Pro TPMS 14.7mbar Resolution 1Hz Transmission IRTPTMS mbar Resolution 1Hz Transmission 5 Pixel IRTPTMS mbar Resolution 1Hz Transmission 5Ch Rim temperature 12.5mbar Resolution 1Hz Transmission In order to avoid competitor teams detecting data a unique serial number is programmed into each sensor. The Sensor number is visibly engraved on the unit. The serial number is key to the TPMS data security protocols. When new or additional sensors are shipped to a customer an encoded file (.pmt) is included via a CD/ . This Permit list must be programmed into all bf1systems equipment using the DigiTyre PC software package supplied. Figure 2-5 Pixel IRTPTMS Sensor

10 bf1systems DigiTyre II User Guide -.doc Page 10 of TPMS Antenna The TPMS antenna is a high sensitivity digital antenna which receives datagrams from specific types of bf1systems wheel sensors (TPMS/IR/5 Pixel/WTS). Data is collated via a LIN bus connection to the ECU. Figure 3 - Motorsport Antenna 6.3 LF Trigger Antenna The LF Trigger Antenna broadcasts a request signal over a range of approximately one metre, and any wheel sensor within that vicinity responds by transmitting a Radio Frequency (RF) datagram back to antenna which is part of the Trigger Antenna, which is mounted in the wheel arch. On closed wheel race cars, a learning system can be installed. The system consists of four LF Trigger Antenna units, one of which is located in each wheel arch. Due to the system s ability to automatically learn the wheel sensors fitted to the car, and start monitoring them, this means that the user will not have to manually assign the wheel sensors as the positioning system. Data is collated in the same way and transmitted via a LIN bus connection to the ECU. Figure 4 - LF Trigger Antenna

11 bf1systems DigiTyre II User Guide -.doc Page 11 of TPMS Motorsport DigiTyre ECUs A number of different ECUs are available for use with bf1systems TPMS wheel sensors. All contain similar functionality, and output data via a high speed CAN bus connection (baud rate configurable). These ECUs include: MDE v2 The MDE v2 is a pin for pin replacement for the original MDE. When used as a part of the positioning system the MDE v2 allows up to four DGA+ antennas to be connected. The MDE v2 can also allow four LF trigger/antenna for a learning system. The MDE v2 is supplied in a high strength enclosure with one size 10 auto sport connector and is configured via RS232. Figure 5 - MDE v2 ECU Kompact MDE The Kompact MDE is the smallest ECU available from bf1systems, and allows for the connection of up to two DGA+ antennas. The Kompact MDE can only be used as part of the positioning system. The Kompact MDE is supplied in a high strength enclosure with three size 2 auto sport connectors and is configured via RS232 Figure 6 - Kompact MDE ECU

12 bf1systems DigiTyre II User Guide -.doc Page 12 of Combined ECU/Antenna The combined ECU/Antenna consists of an internal antenna, which allows for the ECU to replace one of the external antennas required on the 2Ch positioned TPMS. The combined ECU/Antenna is only suited for positioned systems. The Combined ECU/Antenna is supplied in a high strength enclosure with two size 2 auto sport connectors and is configured via CAN. Figure 7 - Combined ECU/Antenna DigiTyre Lite Utilising the same hardware which is used on luxury road cars, the DigiTyre Lite ECU offers IP50 sealing at a reduced cost. The DigiTyre Lite ECU has the same functionality as can be found in the MDE v2 ECU. The DigiTyre Lite ECU is suitable for operation either as a positioned system, or as a learning system. The DigiTyre Lite is supplied with an OEM specification connector and is configured via RS232. Figure 8 - DigiTyre Lite ECU Figure 9-5 Pixel IRTPTMS Wheel Sensor

13 bf1systems DigiTyre II User Guide -.doc Page 13 of 48 7 Component Installation 7.1 Installation of the LF Learning TPMS Wiring If you are not purchasing the TPMS wiring harness from bf1systems, and are planning on building the wiring harness for your car and have not received a wiring schematic then please see appendix of this user guide. Please note that if you are manufacturing the wiring harness, some basic rules should be observed. These are: All CAN wiring must be a twisted pair It is recommended that the +12V and GND wiring to the TPMS ECU should be a twisted pair All wiring going from the TPMS ECU to the LF trigger antennas should be a three core twist For the wiring schematics for the variants of ECU s, Antennas and LF trigger antennas, please see the appendix section in this user guide Learning TPMS ECU Mounting If you have purchased a DigiTyre Lite variant of TPMS ECU then it is important to note that the ECU is not waterproof, and therefore should be mounted in an appropriate location where it will not get wet. If possible, it is recommended that you mount the ECU flat, if it is to be mounted on its side please do so with the connector facing downwards, to prevent water accumulating in the connector. There is no need to AV mount the ECU, and the recommended tightening torque for nuts or bolts to retain the ECU via its mounting lugs is 2.5±0.5Nm. If you have purchased any other ECU for the TPMS then this component is waterproof (once the connector is mated). The ECU can be mounted in environments where it will come into contact with moisture. It is important however to ensure that it will not become completely submerged Mounting of the TPMS LF trigger Antenna With the LF learning TPMS you will receive four Trigger Antennas for fitment to your vehicle. Each LF trigger antenna must be mounted in a wheel arch. The Trigger Antenna is used both to activate the wheel sensors when the car is stationary, allow the TPMS to recognise on which corner each wheel sensor is fitted, and also to receive the datagrams that the wheel sensors transmit. To ensure reliable triggering of the wheel sensors, which means the TPMS can learn the wheels as quickly as possible, the Trigger Antenna must be mounted so that the laser marked side (shown in Figure 8 is facing the centre of the wheel and parallel with the tyre surface. If the car has wheel arch liners, then it is usual for the Trigger Antenna to be mounted to the back of the arch liner. However, if the arch liner is manufactured from carbon fibre then it is necessary to create a window of either Kevlar or glass-fibre to prevent the signal from the Trigger Antenna being reduced. The LF trigger must also be mounted as far outboard as possible on the car, so it sits in-line with the wheel sensor when viewed from above or in front/behind. An illustration of a good position for the Trigger Antenna is shown in Figure 9 Figure 10 - LF Trigger Antenna

It is important however to ensure that it will not become completely submerged.

16 bf1systems DigiTyre II User Guide -.doc Page 16 of Mounting of the TPMS Antenna With your TPMS you will have received antennas with either Size 6 or Size 2 Souriau connectors. The antenna is the component which receives the RF datagrams transmitted from the TPMS wheel sensors, and therefore its positioning is important. With a positioned system, one or two antennas can be supported. It is therefore preferable to mount one antenna at the front of the car, and one antenna at the rear. The antennas receive best through their long side edges, so the antenna should be orientated as shown in Figure 12. If possible, the antenna should be mounted on the axle line, and as close to the centre of the car as possible, to ensure even reception from the wheel sensors. Figure 12 - Correct Orientation of the Antenna The antennas should not be surrounded or encased within either metal or carbon fibre, as both of these materials will attenuate the signals from the wheel sensors, leading to poor reception. On front engine cars, it is usual for the rear antenna to be mounted inside what would normally be the boot compartment, point front to back, and this location tends to work quite well. All TPMS antennas are rated to operate at up to 105 C, and locations where this temperature may be exceeded (e.g. engine bays) should be avoided. If you have any questions regarding the installation of the antennas, please do not hesitate to contact us.

17 bf1systems DigiTyre II User Guide -.doc Page 17 of 48 8 Modes of the TPMS Wheel Sensor 8.1 Storage Mode All sensors are shipped from the factory in the storage mode. This means they are not transmitting information to save battery life; the sensors are measuring changes in pressure. 8.2 Stationary Mode Once the sensor is fitted to the rim and the tyre inflated, the sensor will transition in to a stationary state. Once in this stationary state the sensor will transmit RF datagrams at regular intervals. The accelerometer is used for rotation detection only when active the sensor enters the moving mode, this activation is normally around 30kph. **5 Pixel notes** IN order to preserve battery the 5 Pixel IRTPTMS sensor will not transmit IR data when in the stationary state and below 40 C. In order to activate the 5 Pixel IR Data the user must increase the temperature above 40 C or trigger the sensor from a hand held device such as a mini analyser. 8.3 Moving Mode Once wheel rotation has been detected the sensor enters moving mode where pressure, temperature and IR element datagrams are transmitted at an interval of 1 second. If there is a pressure change of more than 0.2 bar (3 psi) in less than one minute then the sensor will temporarily enter fast transmission mode. The sensor will stay in this mode for a pre-demanded amount of time, after this time the sensor will return to moving mode. 8.4 Quiet Mode This mode is very similar to storage mode, this mode exists to allow a sensor s battery to be preserved between races, when the sensor is fitted to a rim, but no tyre is fitted, or the tyre is de-pressurised below 0.15 bar. The sensors are measuring changes in pressure, and once re-pressurised will transition back in to stationary mode.

Click the update ECU button to save any changes to the ECU and the Save Position File to save to changes to a file for future use. The Maximum number of sets that can be created is 63, the maximum number of cars is 127 and there are 8 tyre options. Note: When a serial number has been allocated to a set then it can be replaced by dragging an unassigned positioned sensor to the set Allowing/Blocking Sensors to the ECU With the TPMS it is possible to allow or block specific wheel sensors from being detected by the system. This is particularly useful if you have more than one car in the same garage. For instance it is possible to stop any wheel sensors that are used with Car #1 from being detected by the ECU on Car #2 and vice versa, only wheels assigned to a specific ECU will be decoded. To block/allow a sensor the user must click on the box beside the sensor, this will toggle the allow/block function. If a tick is present in the box next to the serial number then the sensor will be recognised by the system, if the box is empty then the sensor is blocked by the system and will not be recognised.

26 bf1systems DigiTyre II User Guide -.doc Page 26 of Motorsport Configuration page If an ECU is connected to DigiTyre II the configuration is read automatically from the ECU when the user navigates to this page, this then populates the tables and allows changes to be made to the configuration. After a change has been made it must be written to the ECU using the Write Config button. To check the configuration it is recommended to press the Read Config button and to double check the values. An edited configuration can be saved to a file using the Save Config File button. Please contact your bf1systems representative for the best start-up configuration file required for your application Sensor Location panel Figure 25 - Sensor Location panel on Motorsport Configuration page Locate Mode - The required locate mode is selected in this section and depending on selection the learn and check routines are defined for LF Detect applications. Two options are available from the drop down menu and are as follows; 1. LF Detect - When selected the system will perform the LF Ping function as per settings detailed later in this section. 2. Lookup - The system will revert to the tables created in the position sensor section and the last.posx file entered into the ECU. If you are using the ECU as a position system the rest of this section will not be applicable as it defines the learning behaviour. Mode 2 Checking - When On this will allow the system to accept a wheel sensor ID as part of the check routine although the sensor is in mode 2 (Mode 2 = Sensor in rapid transmit due to detected pressure change). Multipath Receive - When On the antennas can receive any wheel sensor. When Off only the antenna specified for a particular corner can receive that corners data. Note that on systems with less than four antennas, for a 4-wheel application, multi path must be switched on. Multipath Filter - When On only data received by a specific antenna will be sent to the ECU. If the specific antenna does not receive the wheel data then the nearest antenna will be used instead. When Off wheel data received by any antenna will be accepted by the ECU. If all antennas receive a wheel sensor then there will be a four-packet count increment for every single data gram sent by the wheel sensor. Multipath Timeout - The timeout between multipath datagrams, if a second datagram is received within this time the count is not increased (units - milliseconds). LF Ping Code - Choose between LF code 0 and 3 when pinging wheel sensors. Code 0 will only operate with certain sensors and only if they are pressurised. Max Ping Retries (n+1) - This number +1 is the maximum number of times the system attempts to trigger the wheel sensors to get a valid response in any situation. Ser. No. Match Retries (n+1) - This number +1 is the maximum number of attempts the system has to match the received sensor serial number with the previously learnt serial number. This is a function of the check routine. If after X number of attempts the system does not detect a serial number match it will revert to the learn routine, which is detailed in the next two headings. Auto Check Moving - When On the system will perform a check routine when speed is detected. Speed detection can be done via CAN message or via Sensor Moving Detect which is selected in the Setup View panel.

27 bf1systems DigiTyre II User Guide -.doc Page 27 of 48 Ser. No. Learn Counts - The number of times the same serial number needs to be seen during a learn routine. Ser. No. Learn Retries (n+1) - This number +1 is the number of attempts made by the system to achieve the Ser. No. Learn Counts above. It is normal for bf1systems to assist in initial installation of an LF Detect application to fine-tune this element of the system software. Once the routines have been established for the vehicle type there is typically no reason to adjust this functionality Pressure Warning Limits panel Figure 26 - Pressure Warning Limits panel on Motorsport Configuration page Pressure Loss Rate - This is a parameter that the system can use to determine whether or not to wait for the hard warning to be triggered. If a soft warning has been initiated the system will monitor the rate of loss. If the calculated pressure loss rate is greater than the set value the system will immediately trigger a hard warning alarm regardless of current pressure value. Pressure Loss Latch - When On the system will need to be powered cycled before the alarms will clear. Abs Pressure Min - The lowest acceptable pressure that can be present in a tyre before the hard warning is set. This absolute pressure limit value does not increase with changes in temperature. Abs Pressure Max - The maximum acceptable pressure that can be present in a tyre before the hard warning is set. This absolute pressure limit value does not increase with changes in temperature. Soft Warning Limit - This is the maximum amount of pressure deviation from the normalised pressure before the soft warning is triggered. Hard Warning Limit - This is the maximum amount of pressure deviation from the normalised pressure before the hard warning is triggered.

28 bf1systems DigiTyre II User Guide -.doc Page 28 of Setup View panel Figure 27 - Setup View panel on Motorsport Configuration page Lock When Moving - When the moving signal is detected the system will lock onto the last read wheel sensor IDs, this stops the TPMS from being able to receive any other sensor on the track. This will only activate once the prescribed speed is attained and the Moving Time has elapsed. This should always be set to Off when using a Learning system. Sensor Moving Detect - If On and the CAN speed input is not utilised then the system will use the roll switch from the wheel sensor to tell the ECU that the car is moving. The ECU will look at the datagram and when the roll switch bit is set it will assume that the car is now moving. If Off only the CAN speed input will be used to detect vehicle movement. Moving Sensors - Choose from 1 to 4 and the system will wait until it has the matching number of wheel sensors report movement via their roll switch status bits. This option is used as part of the check routine when the vehicle state has changed from stationary to moving. Auto Gen When set to On the system will automatically detect pressure sensor resolution. Auto Set Nominals - When On, the system will set the nominal values automatically once all conditions are met. Nominal values are taken under the same conditions as the lock when moving function. Validate wheels - When Auto Set Nominals is On the system will check for wheel sensor presence before allowing the set function to occur. Off - Checking is disabled and Auto Set Nominals will occur regardless of wheel sensor detection On - Checking is enabled and Auto Set Nominals will not occur until 4 wheels are detected Over Pressure Latch - Enables the user to choose what type of error to be displayed when the sensor goes above the Abs Pressure Max setting. Abs Rx Timeout Pressure - The default pressure the system will revert to in the event of wheel sensor reception failure. It is recommended to go full scale to avoid false pressure loss alarms. Stationary Time - The amount of time that the car must be stationary before new wheels will be accepted by the system. Moving Time - The amount of time that the car must be moving for before the nominal pressure will be set and the wheel sensors are locked in. Stationary Ping Rate - This function applies to LF Detect applications only and refers to a stationary vehicle. The wheel sensors will revert to a stationary mode, when vehicle stops moving, and thus transmit at the rate defined when the parts were manufactured (typically every 30 seconds). From time to time the user may want to have a faster update rate and by utilising this function can use the LF transmitters within the trigger (if mounted) to force datagrams to be transmitted from the wheel sensors up to a maximum of once every second.

29 bf1systems DigiTyre II User Guide -.doc Page 29 of Warning Limits panel Figure 28 - Warning Limits on Motorsport Configuration page Temp. Max On - The maximum acceptable temperature that can be present in a tyre before the Amb Tyre Over temp, hard and soft warnings are set. Temp. Max Off - The temperature threshold below which the temperature in the tyre needs to drop for the Amb Tyre Over temp, hard and soft warnings to be cleared. Battery Life Min - The minimum value that is classed as acceptable. If a sensor is detected below this value an error is flagged. Reference Temp - The temperature to which all wheel sensor pressures and temperatures will be normalised using the ideal gas law. Reference Press - The pressure to which all wheel sensor pressures and temperatures will be normalised using the ideal gas law Timing Params panel Figure 29 - Timing Params on Motorsport Configuration page Response Wait Duration - Duration waited between each ping during the check/learn process (in tenths of milliseconds). Mode2 Wait Duration - If Mode 2 checking is On and the sensor is in mode 2 then this parameter will be used when monitoring the duration between datagrams to determine the sensor not transmitting error. When the timing between datagrams is within this timing the error will be cleared from the Live Update page.

30 bf1systems DigiTyre II User Guide -.doc Page 30 of Advanced button page Figure 30 - Advanced button page Antenna Trig Mode - Because the software provided covers both LF Detect and non-lf Detect applications it is required that the system understand what antenna configuration is employed and more importantly how many antennas are fitted. This also extends to satellite trigger systems where up to six LIN channels are utilised. This enables the ECU to filter antenna errors according to the antenna configuration selected. This also controls antenna multiplexing on 5 and 6 channel systems where both triggers and antennas share the same bus. Failure to select the correct mode may result in difficulty triggering the FL and RL sensors correctly. Pressure Detect Mode Internal Antenna - Turn the internal antenna of certain ECUs On/Off. IR Temp Max On - The maximum acceptable IR object temperature that can be present in a tyre before the IR over temp, hard and soft warnings are set. IR Temp Max Off - The temperature below which the IR object temperature needs to drop for the IR object over temp, hard and soft warnings to be cleared.

34 bf1systems DigiTyre II User Guide -.doc Page 34 of How the Puncture Detection works 10.1 Nominal Pressure Setting When a set of wheels are first installed onto the car (for example at the start of a session) it is required to set nominals using either a push button input or automatically when the car is classified as moving (via the CAN speed input). Once the nominals have been set the pressure and temperature at that time are read and stored internally as a snapshot Pres_Nom_Set and Temp_Nom_Set in the CAN. Using the ideal gas law at the user defined reference temperature, compensated pressure values Pres_Comp_Set are calculated for each wheel. The system will then compensate all live pressure values to be Pres_Comp_Act. This signal is then compared to the Pres_Comp_Set value and if the delta value is outside of the warning values a warning will set. The nominal values are stored in non-volatile memory. When the power is removed the nominal values will be retained. This removes the necessity to have to keep setting the nominal value every time a new set of wheels are fitted, it would normally only need to be set when there is a significant change in the nominal tyre pressure. The system will not allow the nominal pressure to be set until a complete set of wheel signals has been received by the ECU Internal Channel Name Definitions Reference Temperature The reference temperature is the temperature at which all the compensation is performed back to; this is set via the DigiTyre II software. For example the user could set the temperature to be equal to the ambient temperature of the day. Therefore the compensated values will give the theoretical values of the cold pressures Pres_nom_set and Temp_Nom_Set These values are a snapshot and stored value of the pressure and temperature of each wheel when the set nominal command is given. Set pressure is possible through a switch input held high, a wheel speed input above a threshold or a switch press on the dash. This is configured through DigiTyre II. In the example seen in the appendix 11.6 of this document this is 22.8psi and 40 C Pressure and Temperature The real time pressure and temperature of each wheel with no compensation performed. In the example seen in the appendix 11.6 of this document this is 24 psi and 70 C Pres_Comp_Act Actual wheel pressure compensated to reference temperature. This is the pressure as if the wheel sensor were at the reference temperature in other words the cold pressures Abs pressure min limit The abs pressure min limit is set via the configuration in the DigiTyre II. If Pres_Comp_Act falls below the level of Abs pressure min then the hard warning light and output are set Soft warning limit In the graph below there is a difference between the channel value of Pres_comp_set and Pres_Comp_Act of 4.8 psi. This is how the puncture detect software will function. Depending then on the soft warning limit set in DigiTyre II, the soft warning light and output will be set Hard warning limit Set via the configuration in DigiTyre II. If the difference between Pres_comp_set and Pres_Comp_Act is more than the hard warn limit the warning light and output will be set Hard warning time When the soft warning light has been lit the ECU software will monitor the difference between Pres_comp_set and Pres_Comp_Act. If this falls by another soft warning limit in the specified time then the warning limit and output will be set. This is useful if the hard warning limits are large as this gives a rate of pressure loss type warning.

Please note that for the v2 5 Pixel IRTPTMS sensors (part # F1-XXX-1798-YYY-ZZZZ) with serial numbers in the range 5,252,000 5,999,9999, a High Strength sensor screw kit will be supplied in addition to the valve kit that already includes a standard sensor screw kit. It is important that the standard screw kit, which includes the Torx screw, is replaced with the High Strength screw kit which utilises a high strength M5x16 Allen bolt. The v2 5 Pixel wheel sensor requires fastening to the valve assembly with a higher clamping torque than used on other wheel sensors, and this is why a different bolt is required. The standard screw (part no. F A ) with pre-impregnated thread and washer is shown below and this is suitable for use with single pixel IRTPTMS, the v1 5 Pixel IRTPTMS sensors and standard TPMS wheel sensors:

45 bf1systems DigiTyre II User Guide -.doc Page 45 of 48 The High strength screw kit (part no F A) consists of the following components: M5x16 Allen head steel Nickel plated screw grade 12.9, part no. F B M5 Nordlock washer, part no. F A Reinforcement plate, part no. F A The Nordlock washer should be placed onto the M5 bolt, and then the reinforcement plate. Once this is done, Loctite 242 should be applied to the bolt. It is critical that Loctite is applied to the bolt before it is used to fasten the sensor to the valve Installation Remove the existing valve from the rim (if fitted). Check that there are no sharp edges on the valve hole, and that the spot face is clean. Insert the valve stem through the rim; make sure that the small hole in the valve stem is at right angles to the rim, and facing upwards. Place the plain washer over the valve stem. Tighten the nut onto the valve stem using the torque screwdriver or wrench and an 11mm socket; use the small bar to stop the valve rotating. Tighten the nut until the torque screwdriver or wrench breaks free at 7.5Nm. The valve should now not be able to rotate.

46 bf1systems DigiTyre II User Guide -.doc Page 46 of 48 Mount the sensor housing onto the back of the valve using the Torx or Allen head screw (check table 2 to ensure correct screw is selected) and reinforcement plate. Make sure that both of the sensor feet are in contact with the rim. Note that for the Allen head screw Loctite 242 is to be applied to the first few threads of the bolt before it is screwed into the valve. Using the torque screwdriver or wrench tighten the Torx or Allen head screw until the torque tool breaks free at the correct torque (see Table 2). Use the small bar to ensure that the valve is not rotated during the tightening process. If the valve rotates the valve nut MUST be re-torqued. Remove the small bar.

47 bf1systems DigiTyre II User Guide -.doc Page 47 of Notes Do not rotate the valve body or twist the sensor once the valve assembly has been installed. This will cause the valve to loosen and the valve nut will then require re-tightening to the specified torque. The torque settings for the different screws are designed to slightly deform the sensor s Peek housing to ensure that it is fitted with maximum security. This means sensors are not designed to be repeatedly removed from the wheel, so should not be unnecessarily removed from wheel assemblies. New Torx screw are pre-impregnated with thread locker. If a bolt is re-used then it is essential that the bolt is cleaned and Loctite 242 is applied prior to installation. If possible, the bolt should be replaced with a new part Valve and Sensor Removal Set the torque tool to 10Nm. Place the torque bar in the hole on the valve dome, and hold it firmly. Unscrew the TPMS screw. When the thread has disengaged remove the sensor.

48 bf1systems DigiTyre II User Guide -.doc Page 48 of 48 Fit the 11mm socket to the torque driver. Place the torque bar in the hole on the valve dome, and hold it firmly. Unscrew the valve nut. When the thread has disengaged remove the nut, washer and valve. Please note that the TPMS screw can be reused but it should be cleaned and new Loctite 242 applied prior to re-fitment. The valve, nut, washer and sensor can all be reused, providing the sensor housing is unmarked.
