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.
