1 Installation Instructions for: EMS P/N Toyota Supra! WARNING: This installation is not for the tuning novice nor the PC illiterate! Use this system with EXTREME caution! The AEM EMS System allows for total flexibility in engine tuning. Misuse of this product can destroy your engine! If you are not well versed in engine dynamics and the tuning of management systems or are not PC literate, please do not attempt the installation. Refer the installation to a AEM trained tuning shop or call for technical assistance. You should also visit the AEM EMS Tech Forum at NOTE: AEM holds no responsibility for any engine damage that results from the misuse of this product! This product is legal in California for racing vehicles only and should never be used on public highways.

2 Congratulations! You have just purchased the finest Engine Management system for your car at any price! The AEM Engine Management System (EMS) is the result of extensive development on a wide variety of cars. Each system is engineered for the particular application. The AEM EMS differs from all others in several ways. The EMS is an all new stand alone system, which completely replaces the factory ECU and features unique Plug and Play Technology, which means that each system is configured especially for your make and model of car. There is no need to modify your factory wiring harness and in most cases your car may be returned to stock in a matter of minutes. The AEMPro software is configured to work with the factory sensors and equipment, so that there is no need for expensive or hard to find sensors, making replacement and repairs as simple as with an unmodified car. For stock and some slightly modified cars, the AEMPro software will be preprogrammed with a set of base parameters, providing a starting point for individual tuning. For more heavily modified cars, the EMS has many spare inputs and outputs allowing the elimination of separate rev-limiters, boost controllers, nitrous controllers, and fuel computers. It will also allow programmable control over all automatic transmission functions, and includes a configurable onboard data logger capable of recording 512kb of information. Every EMS comes with all functions installed and activated, and there are no expensive options or upgrades to be performed. The installation of the AEM ECU on the Toyota Supra uses the stock sensors and actuators. The base map is automatically installed in the base calibrations directory in the AEMPro directory on your computer. It is named 1110_Stock MAF.V1.03.CAL. Full details of the test vehicle used to generate this map can be found in the files notes section. However, while the base map is a good starting point and may save you considerable time and money, it will not replace the need to tune your specific application. It is not intended to be driven aggressively. Ignoring this can and will damage your engine. Please visit the AEM EMS Tech Forum at and register your EMS before you start to use it. Make sure you enter your EMS serial number when you register as doing this grants access to the calibration files. We always post the most current strategy release, PC Software and base calibrations online. On the forum, you will find many helpful hints/tips to make your EMS perform it s best. Also, we may make available EMS maps for engines running speed density, larger turbo, etc Read and understand these instructions BEFORE attempting to install this product. 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. Page 2 of 7

3 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. 3) You are now ready to begin tuning your vehicle. a) Note: This calibration needs to be properly tuned and is not recommended for street use. NEVER TUNE YOUR VEHICLE WHILE DRIVING. 4) Torque Converter Lockup a) To control the automatic transmission torque converter lockup clutch with the AEM EMS, the Toyota factory ECT ECU must be bypassed. b) Remove the TC lockup control signal wire from connector location SL. See diagram. The ECT ECU is located behind the passenger side kick panel. c) Connect this wire to pin 2C or 3C on the AEM EMS. Pins 2C and 3C are Low Side (LS) outputs that are grounded when ON.
