EMS P/N 30-1100 1993-1998 Toyota Supra TT 1993-1997 Toyota Supra N/A 93-98 Supra 2JZGTE
Instructions: ! This installation is not for the tuning novice nor for the PC illiterate!
Use this system with EXTREME caution! The AEM EMS System allows for total flexibility in engine tuning. 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.

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 1991-1998 Toyota Supra uses the stock sensors and actuators. The base map is automatically installed in the calibrations directory in the AEMPro directory on your computer. It is named 1100.V1.00.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. The factory Supra traction control is not supported with the AEM EMS. No removal of components or other action is required from the end user. The ignition control is converted to “wasted spark” with 3 drivers controlling the six factory coils. The 30-1100 EMS pin out and connector diagram is at the end of this document .
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 under the passenger firewall carpet and has a black cover that is removed by 4 10 mm nuts. b) 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. c) 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. d) Make sure any aftermarket electronics are COMPLETELY and properly removed before starting the vehicle. 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. 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/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. Notes: Installation notes for 30-1100 ECU on Toyota Supra Twin Turbo. The installation of the AEM ECU on the Toyota Supra TT converts the ignition system to a wasted spark system. This change in ignition strategy requires reducing the spark plug gap to .025”. With standard spark plugs, the reduction in plug gap may cause poor idle quality unless the mixture is run richer than 12.5:1 AFR and the ignition timing is reduced to 11 degrees BTDC. We have found that the use of the Denso Iridium Power spark plugs (IQ24 or IQ26) eliminates the idle quality issue when using reduced plug gaps. Additionally, these spark plugs have proven to perform exceptionally well when used in moderate to high boost applications. The Mass air flow sensor is not used as the load input for calibration from AEM. Due to the substantial increase in power by removing the AFM, AEM recommends using a map sensor in speed density measurement. The factory map sensor is good for up to 230 kpa (18 psi) of boost. Above this pressure, it is recommended to use a 3 bar map sensor or higher (Contact AEM for part numbers). Auto Transmission Operation The Wide open throttle shift RPM is based upon when the ECU sends the command to perform the gear change, this DOES NOT mean it will shift at that exact RPM due to mechanical response times for the hydraulic fluid to affect the change. You will have to determine the response time for your transmission by observing the engine speed vs. shift event in AEMLog and adjusting the shift point to occur before the engine reaches maximum rated engine speed.
Connection Diagram for EMS P/N 30-1100 can be found on your computer after the software has been installed. Instruction location: C:\Program Files (x86)\AEM\AEMPro\Instructions
Description of Plug n Play means the Unit plugs into your existing harness. That's it! You still need to install software on your lap top (AEM Pro-Can be found on AEM website for free) and load a calibration as well as set it up and tune.
Warning! Do not buy this if you have no experience with stand alone engine management systems. A professional should be involved in the install and setup process.
