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 also 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 1993-1997 3000GT/Stealth uses the stock
sensors and actuators. The base maps are automatically installed in the base
calibrations directory in the AEMPro directory on your computer. The 91-93 and 94-97
installations use a different base map due to wiring / model feature changes. The EMS
hardware is the same. We have supplied 2 different base calibrations on the CD, one
for each application. You MUST upload the correct calibration to the EMS before you
attempt to start the engine.
1991-1993: 1311-91-93-MAF.v1.11.cal
1994-1997: 1311-94-97-MAF.v1.11.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 EMS does not support the Active Exhaust found on the 91-93 models. If you still
have this, it must be disconnected from the ECU (pin 102). If not disconnected, a
whirring noise will be heard from the AE drive motor located in the left rear quarter panel
on the car. While this causes no damage, it is quite annoying.
The base maps have knock control enabled and can display or log the stock O2
sensors but lambda closed loop A/F control is not activated.
The check engine light is configured as a shift light at 7000 but this value can be
changed.
The stock “boost” gauge is not used.
