1) Removing the Stock Engine Control Unit a) Access the stock Engine Control Unit (ECU). The location of the ECU on the Toyota Supra is behind the Glove box. b) Remove the Phillips head screw on the bottom of the glove box hinge. Remove the glove box by tilting the box at an angle from side to side and slide it toward you. c) Carefully disconnect the wiring harness from the ECU. Avoid excessive stress or pulling on the wires, as this may damage the wiring harness. Some factory ECU’s use a bolt to retain the factory connectors, and it must be removed before the harness can be disconnected. There may be more than one connector, and they must all be removed without damage to work properly with the AEM ECU. Do not cut any of the wires in the factory wiring harness to remove them. d) Remove the fasteners securing the ECU to the car body, and set it aside. Do not destroy or discard the factory ECU, as it can be reinstalled easily for street use and troubleshooting. 2) Install the AEM Engine Management System. a) Plug the factory wiring harness into the AEM ECU, and position it so that the wires are not pulled tight or stressed. Secure it with the provided Velcro fasteners. NOTE: The fourth 6 position factory connector is not used with the AEM EMS. b) Plug the comms cable into the EMS and into your PC. c) Turn your ignition on but do not attempt to start the engine. d) Upload the base calibration file (.cal) that most closely matches your vehicle’s configuration. (These files can be found in the AEMPro/Startup Calibrations/Toyota folder on your computer’s hard drive) e) Set the throttle range: Select the Configure drop down menu, then ECU Setup | Set Throttle Range and then follow the direction given on the screen. f) Verify the ignition timing by selecting the Configure drop down menu, then ECU Setup | Set Ignition. Use a timing light and compare the physical timing numbers to the Parameter Ignition Timing displayed. Use the Advance/Retard buttons to make the timing number match
