Introduction The Centurion Diagnostic Software is a user-friendly software tool able to diagnose engine and system problems. This Windows-based program was designed to communicate with a wide variety of Engine Control Units (ECUs). The interface between the ECU and the PC is via an RS232 interface box. The graphic user interface (GUI), along with the help screens, hotkeys, and mouse support, combine to provide a user friendly system. The main GUI consists of a pull-down menu and a tool bar. The execution of the menu items is accomplished through numeric controls, command button controls, pop-up panels and others. How it Works The ECU is basically a calculator that sends signals to the injectors. The sensors include the temperature of the motor (Harleys head temperature sensor), outside ambient temperature and pressure (altitude), throttle position (TPS), engine speed (RPM) and load (KPA or MAP, manifold absolute pressure). The newer models (2008 and later) also have a narrow band O2 sensor and actually run in closed loop when you tell it to. The ECU combines all data gathered by those sensors and compares it to the actual conditions, making adjustments so that the engine works its best at all times. About this Manual The Centurion User s Guide is a comprehensive guide that contains all of the procedures you will need in order to work with this software. This manual is organized by chapters to assist novice users with getting started. Many topics covered in this manual are also covered in the help menus available in the program itself. This Guide/Manual has been written thinking that not only professionals will use it, but also non-professionals. That is the reason it is written in a non-technical way. 4
1. Setup and installation 1.1 Where to get the Software Insert the CD-ROM from TechnoResearch Inc. into the DVD/CD-ROM drive of your computer OR download from our website* (www.technoresearch.com, go to Support > Downloads). 5

Glossary ECM/ECU (Electronic control module/unit): This is the brain of the motorcycle; it makes calculations based on inputs coming from sensors mounted all over the engine. WOT (Wide open throttle): The maximum opening of the throttle valve. AFR (Air fuel ratio): The relationship of parts of fuel to the parts of air. 13.0(air) to 1(fuel) usually makes the best power, and 14.6 is considered perfect air fuel ratio. This would be the AFR to get an ideal burn (theoretically). This would be at perfect atmospheric conditions and temps, with a perfect atomization which is almost impossible. MAP (Manifold absolute pressure): These sensors measure barometric absolute pressure in the intake manifold. By calculating the mass of the air going into the engine, air temperature, and the rotations per minute of the engine, the engine s ECU can determine the density of the air flowing into the fuel mixture. The ECU can then adjust air flow or fuel flow. CKP or CP (Crank position sensor): This sensor tells the ECM when to fire and inject fuel depending on how fast the engine is running in Revolutions Per Minute. IAT (Intake air temperature): The ECM calculates how dense the air is from this input. ET (Engine temperature): The ECM uses the signals from this sensor to determine if the engine is at operating temperature, or warming up. Fuel Pressure Regulator: A mechanical device usually operated by vacuum form intake manifold that controls fuel pressure. It returns excess fuel from the fuel pump back to the fuel tank. Fuel Injectors: The fuel injectors are electric valves that open and close to deliver fuel in spray form to the cylinder. They are controlled by the ECM to precisely deliver the correct amount of fuel at every engine speed or RPM and any given load. The time of injection is also known as the injector pulse width and is measured in milliseconds. Injectors are rated by their flow rate such as in gm/sec, l/hr or grams per second. Electric Fuel Pump or Fuel Pump: A 12-volt high-pressure fuel pump, usually located in the fuel tank, but it can be located outside as well. It supplies pressurized fuel to the fuel injectors. 45
IAC (Idle air control): An electric valve that s threaded, to open and close as needed to let air into the engine for startup and idle operation when throttle valve is closed. Closed Loop injection system: This circuit has 2 Oxygen sensors. The information on the difference of how much is coming out of the cylinder is relayed to the ECM and then adjusts the amount of fuel injected by shortening or lengthening the time the injectors are open. O2 Oxygen sensor (sniffer): This tells the ECM how much oxygen is in the exhaust mixture so as to have the correct mixture. Anything under 14.7 is considered a rich mixture and anything above 14.7 is considered a lean mixture. RPM (Revolutions per minute): Used to measure engine speed. TPS (Throttle position sensor): You will be dealing with percentages (0 to 100) or Degrees ( ) and/or Volts (V). DDM (Drop down menu): selection of parameters available for a field. 46

Introduction The Direct Link Kit will provide the tuner with the tools and necessary data to maximize the potential of the installed upgrades. The system is designed for Harley-Davidson Fuel Injection equipped motorbikes. How it Works The ECU is basically a calculator that sends signals to the injectors. The sensors include the temperature of the motor (Harleys head temperature sensor), outside ambient temperature and pressure (altitude), throttle position (TPS), engine speed (RPM) and load (KPA or MAP, manifold absolute pressure). The newer models, (2008 and later), also have a narrow band O2 sensor and actually run in closed loop when you tell it to. The ECU combines all data gathered by the above mentioned sensors and compares it to the scribed maps that have been set up at the factory and makes adjustments so that the engine works at its best given the circumstances. About this Manual The Direct Link User s Guide is a comprehensive guide that contains procedures you will need in order to work with this software. This manual is organized by chapters to assist novice users with getting started. Many topics covered in this manual are also covered in the help menus available in the program itself. This Guide/Manual has been written thinking that not only professionals will use it, but also non-professionals. That is the reason it is written in a non-technical way. 3

1.8 Update the Software After the Direct Link software is installed, run the updater to get the latest program versions including the calibrations and the manuals. Click Updater in the bottom right corner: 8
2. Connect the Direct Link Hardware 2.1 Connect the Direct Link to a Motorcycle Connect the Direct Link Flash Tuner and the motorcycle's data link connector using the data link connector cable (4 pin or 6 pin) in the kit. Location of Data link connector: Touring models: Underneath the right side cover. (2008-2012 Underneath the left side cover) Softail models: Underneath the seat. Dyna models: Underneath the left side cover. Sportster models: Underneath the left side cover. VRSC: Underneath the front side neck cover. 2.2 Connect the USB Cable and USB Key Connect the Direct Link hardware USB cable and USB key to the computer. 9
3. Starting the Direct Link Software 3.1 Security Key and Cable Make sure the hardware is connected as shown in Section 2.1-2.3 (above section). 3.2 Run the Program Click Direct Link Race Performance icon on the desktop to run the software. 3.3 Disclaimer/Language selection Click Accept to agree to the terms of use and select a Language preference to launch to software. 10
Shown below is the programming screen and where you will do a lot of your work. You should play with this screen and practice opening and closing editing tables and connecting to the motorcycle. Each table you edit will change something on the motorcycle and you will always program the ECU from this screen. 3.4 Select the COM Port Under Communication, select Port Setting. Important: If the Direct Link hardware (VCM) is not powered, then the correct COM Port will not appear (indicated by an illuminated LED). To rectify, press Cancel and power the Direct Link hardware by turning on the ignition switch and making sure the engine stop/run switch is in the RUN position. Once the LED light is on, the Direct Link hardware is on, select Communication and Port Setting again to select the correct COM Port. 11
3.5 COM Port Setting if None is showing and No Other Option is Given If the COM port is not showing, it means that the driver for it was not correctly installed when installing the software. Go to the computers Control Panel, select Hardware and Sound, select Device Manager. If the COM port is not showing, the yellow triangle icon will appear: IMPORTANT: This means that the driver was not correctly installed when installing the Centurion U/UE/M/S software. When you right click and select Update Driver Software, you can manually browse and point the search at your CD/DVD drive if the software CD is in, OR search automatically and the files should be pulled. 12
After the correct device driver is installed or updated, the window will look like this: Go back to the Port Setting window in the software and make sure the corresponding number is selected in this case, COM14. 13
4. Toolbar Icon Descriptions 4.1 Main Menu The Direct Link main menu offers a variety of commands. Below the main menu are the Toolbar Buttons, which offer quick access to the most often used commands. 4.2 Tab Menu File Menu: Commands to open, export, backup or save a file, close an active window, and quit the program Edit-Table: Access to editable tables and engine settings View Menu: Contains commands related to what mode you are viewing Communication: Commands for connecting, disconnecting, and programming Options: Trace and data record settings, access to Mobile Dyno, settings to change units and colors Help: Displays a variety of help commands 14

5. Key Features 5.1 Creating a Backup Note: Always save the original calibration before programming the new calibration. That way, the motorcycle can be restored to stock at any time. Precautions: During the backup and programming, the ECU must be powered correctly. Therefore, we recommend removing the LIGHT fuse and using a charger to be sure that the voltage is correct. With the ignition switch on and the engine stop switch in the RUN position, click Backup Original Map. This will back up the original map from the ECU so that, at a later date, the motorcycle can be restored to stock if needed. 16
Select a location and name for the Backup Map and click on Save Direct Link will now read and save the original bike map. After the status bar has reached 100, check for the green PASS to ensure that all operations have concluded successfully. Note: Do not disconnect the USB Hardware Key. This could damage the key. 17
5.2 Loading a Map Before loading a map, check what map is in the motorcycle ECU by pressing the button ECU Info. The application # will show the correct map model (105, 127, 176, etc.) Open a calibration via File > Open Calibration > Modified or click the Open Calibration icon. This will open a file selection window. Find the map best suited to load and click Load. (The Application # mentioned above is usually in the end of the map file name. The Info button next to the app # can be used as a quick reference for matching). 18
Once loaded, the Calibration Information can be reviewed and compared with that of the ECU. 19
5.3 Important Tables (Check before first flash) The following tables can be found under the Edit-Table drop down, or by using the toolbar buttons shown: 5.3.1 VE Table 20
5.3.2 Spark Table 21
5.3.3 AFR Ratio Table The values in the AFR (Air-Fuel Ratio) table are calculations that the ECU uses to determine the injector pulse width. The AFR does not actually change. This is the main fuel table that the ECU will try to achieve. The tuning process changes the VE (Volumetric Efficiency) tables so that the live AFR data is as close to AFR table. You can, and should, change the VE s on each cylinder separately. They each have different requirements and the fuel injectors may not be matched for flow. There are (2) methods to accomplish this Set the AFR Ratio Table in open loop but close to the final Target values. The other method is to set all of the values to the same constant (13.2-13.5). Once the values are in place, click on the Apply button to apply the changes, then the OK button to conclude the modification. Note: When working on the closed-loop models, changing the AFR value to anything other than 14.6 disables closed-loop operation which makes VE table tuning possible. 22
5.3.4 Cranking Fuel Make sure to check this table. The cold temperature numbers should have more fuel than the hot temperature numbers. Double click on an msec cell and use the up and down arrow to adjust. The values above a temperature of 233F may have to be adjusted up or down to get the bike to start quickly. Click OK. See this example of a typical Cranking Fuel table: 23
5.3.5 Idle Table Make sure to check this table. Double click on an RPM cell and use the up and down arrow to adjust. Remember to let the engine get to working temperature before making any changes. Click OK. See this example of a typical idle table: 24
5.3.6 IAC Table Make sure to check this table. This table may need to be adjusted while tuning to make sure bike is idling up on startup, and when at operating temperature, the idle is stable. Check live data and verify that the actual stepper counts are not lower than the programmed stepper counts. The actual Steps should be the same or slightly lower than the programmed values. Double click on a STEPS cell and use the up and down arrow to adjust. Click OK. See this example of a typical IAC Table: 25
5.3.7 Acceleration Table Make sure to check this table. The accel table needs to be adjusted during tuning so the bike will have crisp response when blipping the throttle and no black smoke comes out of the exhaust. Double click on a STEPS cell and use the up and down arrow to adjust. Click OK. TIP: Create a table that lists the changes in calibrations that have been modified just in case you want to go over your own work before saving. 26
5.3.8 Decel (Deceleration) Table Make sure to check this table during tuning if decel popping is occurring. This table allows the removal of a small amount of fuel during a decrease in throttle position, or during a decrease in manifold pressure. This fuel gets subtracted from the base pulse width calculation. Larger values increase the fuel removed. Smaller values decrease the fuel removed. Double click on a STEPS cell and use the up and down arrow to adjust. Click OK. 27
5.3.9 Closed Loop This table can be left alone for tuning, as the AFR Table has been set so the bike will always be in open loop and not be using the factory Oxygen sensors. Only when the AFR table is at 14.6 will this table be active and used. There are (2) types of closed loop systems now. The older bikes use closed loop biasing and the new bikes do not. The new bikes can be set from 14.3-14.6 for closed loop. The old bikes with the bias table have the AFR value or millivolt setting centered at 450volts. Setting this table to 680 will yield something like 14.5-14.6 AFR Value. You cannot set this mv value much higher, as the O2 sensor will not switch properly and will drive the fuel rich. The sensor needs to switch around a center point. 28
5.3.10 Warm-up Fuel table Make sure to check this table. This table needs to be minimized as much as possible so gas is not being wasted on warm-up. Double click on an AFR cell and use the up and down arrow to adjust. Click OK. See this example of a typical Warm-up Fuel Table: 29
5.4 Additional Checks (Check before first flash) The following tables can be found under the Edit-Table menu, or by using the toolbar buttons shown: 5.4.1 Knock Sensor This should be turned on when the timing table is being adjusted and click OK to save. 5.4.2 Engine Parameters The settings for Engine size and injector size should be set to match what the engine really is. These parameters may need to be adjusted to alter the VE tables off of maximum values. Try to leave the cubic inch values matched to the motor and move the injector values to allow the VE tables to be in spec. Click on a parameter and use the arrows to adjust. Click OK to save. 30
5.4.3 Calibration Note It is a good idea to detail what modifications the engine has CAMS, pipes, air box, etc. (It is recommended that First ECU flash is noted when applicable). 31
5.4.4 Throttle grip This table sets the maximum throttle valve opening at a specific throttle grip setting and RPM. This table needs to be set before any tuning is done. All of the tables have been checked and it is time to flash the ECU for the first time. We will be flashing many times once the tuning of the VE tables and the adjustment of the spark tables starts. The first flash has to be done to register all of the changes just made. After this we start the tuning process. Note: A re-flash is always necessary for any changes to take effect. 32
6. Program the Calibration into the ECU For all practical purposes, this describes what to do on a relatively stock or only slightly modified motor (cams, pipes, air breather and/or heads). 6.1 Save Original Calibration After saving the original calibration (see 5.1), start to tune the calibration. Note: Open the Edit-Table menu and click on Engine Setting. The displacement can be set if you ve changed that and the injector size. This is very handy because if the injectors are changed later, the software can input the new size and it will compensate for larger injectors or a big bore kit. 33
6.2 Check ECU Information Check the current motorcycle ECU information first by pressing ECU Info (see 5.2 for more details). 34
6.3 Select Calibration Select a starting calibration or modified calibration that most closely matches the motorcycles current setup (see 5.2 for more details). Click Load. 6.4 Run Turn on the ignition switch and make sure the engine stop switch is in the RUN position. 35
6.5 Program Go to Communication menu and select Program or just click Program button to upload new calibration into the ECU. Note: Do not disconnect the Direct Link key. This could damage the key. This will load a map into the system. The processing status is indicated on the progress status bar: 6.6 Programming Status At the end of the programming mode, a PASS or FAIL message will be displayed. FAIL: If during the programming an error message/fail message appears, disconnect the ECM/ECU for 30 seconds, then reconnect, and begin programming again. Please also double check the wiring and adaptors being used. (Note: If this message persists, remove all the fuses and relays from the fuse box of the bike except the ECM/ECU and ignition fuses. Reprogram the ECM/ECU and put back all the fuses.) PASS: After successfully programming the ECU, turn ignition off, wait 10 seconds and turn ignition on again. Then start and run the bike. 36
7. How to Save the Modified Calibration 7.1 Save as Click the Save as icon or go to File menu and select Save As. Note: Always save the original calibration before programming the new calibration. That way, the motorcycle can be restored to stock at any time. Type a new file name. Click Save. TIP: Name the file a special name so you don t have any problems finding and opening the new modified file. You should always retrieve your stock tune and save it before you make any changes so you can go back to the stock tune in case any errors were made. 37
7.3 Calibration Information Calibration ID and Calibration Note can be edited or modified. Click OK when finished. 8. How to Change Units 8.1 Options Go to Options menu and select Units. Select the preferred unit. Click OK. 38

NOTE: Make sure the starter map you want is loaded and programmed before continuing. 48
11.2 Logging Data with a Dyno While in Strip Chart mode, click Connect and wait for the bike to connect. Select the Auto Map icon. Select Dyno and click OK. Click Start Session. 49
When finished logging, click End Session. A prompt will open click OK to automatically load the log. TIP: To open previous Logging Sessions click the Open Log icon ( ), select the run and click Load. Click Create Map. Choose the tables to be modified and the O2 sensors that were used. Make changes to the VE Tables and click OK when finished. To save, click the Save icon ( ). Now go back to the re-flash screen ( ), open the new calibration and program it to the ECU. NOTE: Make sure to BACKUP the original calibration so the motorcycle can be restored back to stock if necessary. 50
11.3 Logging Data with Mobile Dyno NOTE: Be sure the same channels shown in 11.1 are selected. Select the Auto Map icon. Select Mobile Dyno and click OK. Click Start Session. A prompt will ask to configure the VCM. Select Yes. Unplug the VCM from the computer and the motorcycle (the VCM s power source). The next time the box gets power, it will begin recording. When ready to ride, connect the box to the bike again. It will now begin to log data (up to ~15 minutes worth). The green LED on the VCM will blink, signifying that it is recording. When finished logging, turn the bike off for at least 15s. Connect the VCM back up to the computer and turn the bike back on. Select End Session. 51

NOTE: Make sure to BACKUP the original calibration so the motorcycle can be restored back to stock if necessary. 53
Glossary ECM/ECU (Electronic control module/unit): This is the brain of the motorcycle; it makes calculations based on inputs coming from sensors mounted all over the engine. WOT (Wide open throttle): The maximum opening of the throttle valve. AFR (Air fuel ratio): The relationship of parts of fuel to the parts of air. 13.0(air) to 1(fuel) usually makes the best power, and 14.6 is considered perfect air fuel ratio. This would be the AFR to get an ideal burn (theoretically). This would be at perfect atmospheric conditions and temps, with a perfect atomization which is almost impossible. VE (Volumetric efficiency): This is the most important part of tuning. If the computer knows the volumetric efficiency, it can decide how much fuel to add to run best. It is how you tell it to add or subtract fuel and is one of only two variables you can adjust to get the AFR correct. The O2 sensor will aid in your adjustments. MAP (Manifold absolute pressure): These sensors measure barometric absolute pressure in the intake manifold. By calculating the mass of the air going into the engine, air temperature, and the rotations per minute of the engine, the engine s ECU can determine the density of the air flowing into the fuel mixture. The ECU can then adjust air flow or fuel flow. CKP or CP (Crank position sensor): This sensor tells the ECM when to fire and inject fuel depending on how fast the engine is running in revolutions per minute. IAT (Intake air temperature): The ECM calculates how dense the air is from this input. ET (Engine temperature): The ECM uses the signals from this sensor to determine if the engine is at operating temperature, or warming up. Fuel Pressure Regulator: A mechanical device usually operated by vacuum form intake manifold that controls fuel pressure. It returns excess fuel from the fuel pump back to the fuel tank. Fuel Injectors: The fuel injectors are electric valves that open and close to deliver fuel in spray form to the cylinder. They are controlled by the ECM to precisely deliver the correct amount of fuel at every engine speed, or RPM, and any given load. The time of injection is also known as the injector pulse width and is measured in milliseconds. Injectors are rated by their flow rate such as in gm/sec, l/hr or grams per second. 54
Electric Fuel Pump or Fuel Pump: A 12-volt high-pressure fuel pump, usually located in the fuel tank, but it can be located outside as well. It supplies pressurized fuel to the fuel injectors. IAC (Idle air control): An electric valve that s threaded to open and close as needed. This lets air into the engine for start-up, and idle operation when throttle valve is closed. Closed Loop injection system: This circuit has 2 Oxygen sensors. The information on the difference of how much is coming out of the cylinder is relayed to the ECM and then adjusts the amount of fuel injected by shortening or lengthening the time the injectors are open. O2 Oxygen sensor (sniffer): Tells the ECM how much oxygen is in the exhaust mixture so as to adjust to have the correct mixture. RPM (Revolutions per minute): Used to measure engine speed. TPS (Throttle position sensor): You will be dealing with percentages (0 to 100). 55

Important Information The following information should be noted before beginning diagnostics on Delphi and Marelli ECUs. Feedback vs No/Limited Feedback Limited/No Feedback: the software will ask the ECU to do something and the ECU will confirm that the request was received, but it will not confirm that the request was actualized. Feedback: the software will ask the ECU to do something and the ECU will confirm that the request was received AND that the request was actualized. The Delphi is a No/Limited Feedback ECU The Marelli is a Feedback ECU Practical Application of This Knowledge When working on a motorcycle powered by a Delphi ECU with Centurion Super Pro, a "Passed" activation on a Fuel Indicator active test means that the ECU has accepted and understands the request to turn on the Fuel Indicator. It is necessary for the technician to confirm that the ECU was able activate that indicator. 3

1. Key Features For more in depth information on installing and opening the software, see manual pages 4-13. 1.1 Creating a Backup NOTE: Always save the original calibration before programming the new calibration. That way, you can restore your motorcycle back to stock. Precautions: During the backup and programming, the ECU must be powered correctly. Therefore, we recommend removing the LIGHT fuse and using a charger to be sure that the voltage is correct. Click Backup Original Map. This will back up the original map from the ECU so that, at a later date, you can restore the motorcycle back to stock if needed. Turn on the ignition switch and make sure the engine stop switch is in the RUN position. Click OK. 2

Select a location and name for your Backup Map and click on Save Direct Link will now read and save your original bike map. 4
After the status bar has reached 100, check for the green PASS to ensure that all operations have concluded successfully. Note: Do not disconnect the USB Hardware Key. This could damage the key. 5
1.2 Loading a Map Before loading a map, check what map is in the motorcycle ECU by pressing the button ECU Info. The application # will tell you the correct map model (105, 127, 176, etc.). Open a calibration via File > Open Calibration > Modified or click the Open Calibration icon. This will open a file selection window. Find the map you wish to load and click Load. (The Application # mentioned above is usually in the end of the map file name. The Info button next to the app # can be used as a quick reference for matching). For a more in depth overview of the toolbar buttons, see manual pages 14-15. 6
Once loaded, you can quickly review your Calibration Information and compare with that of the ECU. 7
2. Open Loop, Closed Loop, and How They Affect Tuning All Harley-Davidsons models up to 2006 are always in Open Loop. Harley s started using O2 sensors with the 2006 EFI Dyna models. From 2007 an onward, Closed Loop was possible because of the motorcycles factory installed O2 sensors. Closed Loop is the state of the ECU in which it DOES make its own VE changes based on O2 sensor information. Open Loop is the state of the ECU in which it does NOT make its own VE changes based on O2 sensor information. Open Loop is an important status to use when making your own changes so that the VE tables remain constant throughout your data acquisitions. If the ECU is making adjustments while Direct Link is trying to determine what value the ECU needs to change by, the results will be inconsistent. Imagine trying to adjust a scope for distance using an object that is randomly moving closer and further away without any indication, warning, or consistency. This is what tuning in Closed Loop is. Closed Loop - usually activated by setting AFR desired values to 14.6 AFR, the range can be 14.1-14.6. Direct Link will make the values bold to indicate that they are in Closed Loop, giving the ECU permission to change them. Open Loop - usually activated by setting AFR desired values to anything BUT 14.6 AFR, the range can be 14.1-14.6. (Any cell without a bold value will be in Open Loop.) 8
3. Auto-mapping 3.1 Select Strip Chart and Channels Go to the Strip Chart screen. Select the following channels by selecting the Channels/Mode button.

You will get a prompt from the system letting you know that you MUST select these channels in order to Automap. NOTE: Make sure the starter map you want is loaded and programmed before continuing. 10
3.2 Logging Data with a Dyno While in Strip Chart mode, click Connect and wait for the bike to connect. Select the Auto Map icon. Select Dyno and click OK. Click Start Session. 11
When you are finished logging, click End Session. A prompt will open click OK to automatically load the log. TIP: To open previous Logging Sessions click the Open Log icon ( ), select your run and click Load. Click Create Map. Choose the tables to be modified and the O2 sensors that were used. Make changes to the VE Tables and click OK when finished. To save, click the Save icon ( ). You can now go back to the re-flash screen ( ), open your new calibration and program it to the ECU. NOTE: Make sure to BACKUP the original calibration so the motorcycle can be restored back to stock if necessary. 12
3.3 Logging Data with Mobile Dyno NOTE: Be sure the same channels shown in 3.1 are selected. Select the Auto Map icon. Select Mobile Dyno and click OK. Click Start Session. A prompt will ask you to configure the VCM. Select Yes. Unplug the VCM from the computer and the motorcycle (the VCM s power source). The next time the box gets power, it will begin recording. When ready to ride, connect the box to the bike again. It will now begin to log data (up to ~15 minutes worth). The green LED on the VCM will blink, signifying that it is recording. When you are finished logging, turn the bike off for at least 15s. Connect the VCM back up to the computer and turn the bike back on. Select End Session. 13
The log file will automatically download and then load. Click Create Map. 14
Choose your tables to be modified and the O2 sensors that were used. Make changes to the VE Tables and click OK when finished. To save, click the Save icon ( ). Now go back to the re-flash screen ( ), open the new calibration and program it to the ECU. NOTE: Make sure to BACKUP the original calibration so the motorcycle can be restored back to stock if necessary. 15
4. Tables 4.1 Fuel Map The Fuel Maps (VE Tables) are a table of values that dictate the calculated volume of fuel/air mixture (the charge) that will fit in the cylinders, this is called Volumetric Efficiency and can be thought of as "cylinder fill". The VE tables are a chart of the VE values, or possible cylinder fill, at differing throttle positions and engine RPMs. (Sometimes MAP is used in place of the throttle position.) A larger VE means there can be more "charge" (air and fuel mixture) in the cylinder (Richer) at that point of TPS and RPM. A smaller VE means there can be less "charge" (air and fuel mixture) in the cylinder (Leaner) at that point of TPS and RPM. 16
4.2 Spark Map Measured in degrees before Top Dead Center (btdc). 0 is TDC. The idea is to ignite the charge at the right time during the pistons upward stroke so that the explosion is timed with the downward stroke. Because there are so many factors influencing how a charge will ignite and behave, here are some generic tips: Low Throttle or MAP = increased spark advance Higher Throttle or MAP = decreased spark advance Lower RPM = decreased spark advance Higher RPM = increased spark advance Colder Engine = increased spark advance Warmer Engine = decreased spark advance 17
4.3 AFR Air to Fuel Ratio. This tells the ECU how much fuel to mix with the intake air, creating the "charge". TIP: Why is more actually less when it comes to AFR and richness? The relationship is Air (i.e. 14.6)/Fuel (i.e. 1) = AFR. Raising the AFR value increases the amount of AIR in the "charge" by decreasing the amount of Fuel in the mixture. The AFR memory trick: When trying to remember why the AFR values change the engine as they do, it is easier to imagine that you are only changing the air (the A comes first in AFR). Bigger numbers = More air in the charge = less fuel in the charge = Leaner Smaller numbers = Less air in the charge = more fuel in the charge = Richer 18
