WARNING: This installation is not for the tuning novice! Use this system with EXTREME caution! The AEM
Infinity Programmable EMS allows for total flexibility in engine tuning. Misuse or improper tuning of this
product can destroy your engine! If you are not well versed in engine dynamics and the tuning of engine
management systems DO NOT attempt the installation. Refer the installation to an AEM-trained tuning
shop or call 800-423-0046 for technical assistance.
NOTE: All supplied AEM calibrations, Wizards and other tuning information are offered as potential
starting points only. IT IS THE RESPONSIBILITY OF THE ENGINE TUNER TO ULTIMATELY CONFIRM IF THE
CALIBRATION IS SAFE FOR ITS INTENDED USE. AEM holds no responsibility for any engine damage that
results from the misuse or mistuning of this product!

OVERVIEW
The AEM Infinity EMS can be adapted to most fuel injected engines. The base configuration files
available for the Infinity ECU are starting points only and will need to be modified for your specific
application. This manual lists the files available and suggested changes for your engine. It also includes
a pinout with suggestions for adapting the Infinity ECU to your engine harness. It is the responsibility of
the installer to verify this information before starting the engine.

To properly control your engine, the application specific settings listed in this document MUST be
confirmed or changed to the given settings. Failure to do so may result in improper function and possible
ECU damage.
ADAPTER HARNESS OPTIONS
30-3702 Harness, Mini Lead
This harness includes a fused power distribution center with main relay. Pre-terminated connectors are
available for the internal UEGO sensors and AEMNet. A bag of multi-color flying leads is included to
simplify custom harness builds.
30-3701 Connector Kit
This kit includes mating connectors and terminals for the Infinity. It also includes a main relay kit which
is necessary for proper power distribution. This kit is best suited for experienced installers who want to
build their own harness.
