1 Speed-Pro EFI Installation Manual Speed-Pro Electronics Installation Manual Page The wiring harness is labeled on each of the connectors to simplify installation. Your application may not require the use of all the connectors in the harness. You may also require additional accessories such as relays, sensors, and other specialized connectors to complete your installation. Care should be taken to route all wires as far away from the distributor and spark plug wires as possible to minimize interference from ignition noise. POINTS Unless specifically noted otherwise, this wire is to be connected only if an inductive pickup ignition system is used. Connect this wire to the points input wire on your aftermarket ignition system. Do not connect this wire if you are using your factory ignition system. FUEL Connect this wire to the negative side of a relay used to power your fuel pump (relay not included). This output switches to ground when active. Do not connect this wire to the positive side of the relay or any positive voltage source! Relays are available in 0 amp (part # 0-700) and 0 amp (part # 0-70) versions. For high-current applications, a 7-amp version (part # 0-709) is available. A relay must be used do not connect this output directly to a fuel pump! FAN Connect this wire to the negative side of a relay used to power your fan (relay not included). This output switches to ground when active. Do not connect this wire to the positive side of the relay or any positive voltage source! Fan control is available on bank-tobank systems only. Relays are available in 0 amp (part # 0-700) and 0 amp (part # 0-70) versions. For high-current applications, a 7-amp version (part # 0-709) is available. A relay must be used do not connect this output directly to a fan! ESC / Cam For most Bank to Bank applications, connect this wire to a GM-type ESC module, typically located on the firewall or inner fender. The knock sensor used should be a GM-type knock sensor. Use of the knock sensor is not recommended for applications where high-octane fuel is used. In some special cases, this input is also used for a hall effect CAM sync signal. C-COM Connect this plug to the supplied RS- communications cable for connection to your computer s serial port. If the supplied cable is not long enough for your needs, a -foot RS- cable (part # 0-80) is available.

2 Page N O If the nitrous oxide control option is used, connect this plug to the supplied nitrous oxide control harness. To connect the control harness to your system: PINK WIRE +V for nitrous enable RED WIRE Connect to +V source ORANGE WIRE Connect to positive side of st stage nitrous solenoid BROWN WIRE -- Connect to positive side of nd stage nitrous solenoid (if used) V+ SWITCHED Connect to a +V source that is active when the key is in the START and RUN position. This is the wire that actually turns the ECU on, so it is critical that it receives volts when the key is in the ON position and in the START position. GROUND This ground connection is used for the relay in the wiring harness and should be connected to a clean chassis ground. Be sure to remove all paint and corrosion from the point to which this ground is attached. BAT+ and BAT- The battery wires should only be connected to the battery terminals, not to an intermediate power source or ground on the chassis or engine. This will ensure maximum noise rejection from ground loops and conducted noise. Connect these only after all other connections are made. WIDE BAND O If the Wide Band Oxygen Sensor option is being used, connect this plug to the supplied oxygen sensor, using the provided extension harness as needed. The Wide Band Oxygen Sensor option is available for bank-to-bank and sequential control units. H 0 Connect this plug to a GM-type coolant temperature sensor, such as Speed-Pro part # AIR Connect this plug to a GM-type air temperature sensor, such as Speed-Pro part # For speed/density applications, this sensor should be mounted in a position where it samples the charge air in the manifold. For Alpha-N applications, mount this sensor to sample ambient air temperature, as in the hood scoop or in the air cleaner.

3 Page MAP Connect this plug to a GM-type Manifold Absolute Pressure sensor, such as Speed-Pro part # for normally aspirated applications. For blown or turbocharged applications, use a bar MAP sensor (part # ) for up to PSI of boost and a bar MAP sensor (part # ) for up to 0 PSI of boost. For speed/density applications, this sensor must be connected to an intake manifold vacuum port. For Alpha-N applications, mount this sensor to sample ambient air pressure, as in the hood scoop or in the air cleaner. TPS Connect this plug to the throttle position sensor located on the throttle body, such as Speed-Pro part # (GM applications) or part # for Ford applications. IAC If the Idle Air Control option is being used, connect this plug to the Idle Air Control motor. Use Speed-Pro part # 0-70 for GM TBI and TPI applications. Use part # 0-70 for GM LT- and LT- applications. For Ford applications, use part # 0-70 with Idle Air Control adapter part # For blown, turbocharged, or other special applications, use Remote Idle Air Control unit, part # CAM Connect this plug to the Camshaft Sensor, and connect the ring terminal to a ground point such as the engine block. A cam sensor input is only needed for sequential systems with inductive pickup ignitions. If your engine does not have a camshaft sensor and one is required, contact your Speed-Pro dealer for assistance. Bank-to-bank configurations do not require a cam sensor, even with IPU ignitions. CRANK Connect this plug to the Crankshaft Sensor, and connect the ring terminal to a ground point such as the engine block. A crank sensor input is only needed for inductive pickup ignitions. O.E. IGNITION NOTE: Inductive pickup ignition systems will not use this connector. This plug is used to connect to your vehicle s factory ignition system. It can easily be adapted to many different ignition types. The four pins on this connector are labeled A, B, C, and D. A connector is provided for you to create your own adapter for your ignition system. The following diagrams outline adapter configurations for the following ignition systems:

5 Page INJECTOR This plug will be connected to the supplied fuel injector harness. If specified at the time of order, the harness can be configured for your specific firing order. Otherwise, injector harnesses are shipped for a standard GM V8 firing order (87). If you need to reconfigure your injector harness, refer to the following chart. The 0-pin connector on the end of the injector harness can easily be reconfigured to work with many different engine types. Terminals A through H on the connector are designated for each of the eight injector connectors on the harness and can be reconfigured as per the following chart. Terminals J and K should not be changed under any circumstances. The configurations in this chart are set up with the injector harness plug on the opposite side of the motor as the distributor to minimize interference from ignition noise. The harness is also configured to operate the injectors in a fashion that minimizes fuel pressure loss. Injector Harness A B C D E F G H Most GM V8 (87) S.B. Chrysler (87) 7 8 GM LT- V8 (87) B.B.

Crank Sensor Wire Colors Red (Mag+) Terminal A (Mag-) Terminal B MSD Distributor Violet/ / MSD Crank Trigger Violet ACCEL 000 Series White ACCEL Crank Trigger White. Install the crank pickup so that the # cylinder trigger occurs at 0 BTDC of the compression stroke on the crank. Set the Crank Ref. Angle box in the ECU configuration in C-Com to indicate 0. If the engine is a high-revving one that uses a lot of advance, use 0 as the position.. Set the rotor position to line up with the # spark plug terminal in distributor cap. If you are using a sequential system, verify that the cam trigger occurs at least 0 sooner than the crank trigger, but not more than sooner. Bank-to-bank systems do not require a cam trigger.. Confirm that rotor phase will not be a problem over the expected range of advance timing and adjust rotor phase accordingly.. If the Individual Cylinder Control option is being used, verification of timing and individual cylinder correction can be performed by checking the timing with a timing light and making sure that the timing indicated on the crank is the same as in the Spark Table for the given operating conditions. Small changes to the Crank Ref. Angle box in the Configuration Menu in C-Com can be made to correct the timing if a small change is necessary to calibrate crank timing with the Spark Table timing. Correct cylinder synchronization can be tested by retarding the timing in cylinder # by 0 from the C-Com Individual Cylinder Correction Menu and verifying that the timing, indicated by a timing light, changes by 0. This test should only be performed while the engine is above 000 RPM, as synchronization is not enforced below this RPM.

7 Page 7 Getting your car started To verify proper connection of the wiring harness, connect your computer to the ECU with the provided communications cable. Start the C-Com software from the C:\ prompt by typing: CD\C-COM [enter] CC [enter] If the computer is communicating properly with the ECU, a small black box with two red dots in the upper left-hand corner of the screen should appear. If a tan box with the word FILE appears, press the F key to attempt communication. If you are unable to communicate with the ECU from your computer, refer to section 7.0 in the C-Com reference manual. Once the computer is connected and on-line, press the F9 key to display the dashboard. You should be able to read the following dashboard parameters with the engine not running and the key in the ON position: The TPS should be at approximately % at idle and over 80% at wide open throttle (WOT). The MAP sensor should read approximately 00 kpa. The air and coolant temperature sensors should read the approximate outside temperature. An RPM signal should be present when cranking the vehicle. If you do not see an RPM change when cranking the vehicle, refer to the paragraphs below on setting the ignition and crankshaft reference angle. Battery voltage should be - VDC. The ECU comes with a calibration file that should be sufficient to get most engines started. However, before attempting to start your car, there are a few parameters that must be set. These include engine firing order, injector flow rate, crankshaft reference angle, and engine displacement. These parameters can be accessed in the configuration section from the C-Com main menu screen. If you are using your factory ignition system, the ignition timing should be set according to the manufacturer s specifications, which are typically: GM HEI Six degrees GM Optispark Six degrees Buick DIS Ten degrees Ford TFI Ten degrees The crankshaft reference angle in the ECU configuration screen should be set to the same value as the ignition timing. With these parameters correctly set, most users should be able to start the vehicle at this point. Please note that this is not a race ready configuration; you will need to tune your ECU for your specific application once you start the vehicle. Consult your dealer/installer for specific tuning guidelines. The manufacturer typically specifies injector flow rate at psi.
