AEM's Evo Plug and Play Engine Management System (EMS) is a user-programmable full standalone ECU. Replacing your Evo's stock ECU with an AEM EMS is simple, it literally plugs directly into the stock wiring harness. The AEM EMS's Windows-based software makes tuning, injector scaling, and sensor calibration a simple process. User-Defined templates make tuning the AEM EMS even simpler, as you can establish quick keys to speed up the tuning process. While professional tuning is required, the Evo 8 EMS also comes with stock base maps, to get the car running, and speed along the tuning process.

The AEM EMS standalone ECU for the Evo is infinitely adjustable, and with the large variety of available sensors (i.e. MAP, EGT, IAT, etc.) advanced tuners can set vehicles up for advanced, more complex features. When used with the optional AEM or an external wideband UEGO wideband (sold separately), the AEM EMS has the capability to auto-tune fuel curves. In addition, the datalogging capabilites of this system are second to none.

SPEED DENSITY CAPABILITY: The AEM Evo EMS system can eliminate the factory mass airflow sensor, using the included speed density basemap and optional 3.5 BAR MAP sensor (30-2130-50) and Inlet Air Temp Sensor (30-2010). AEM reccomends purchasing and using these sensors as the Speed Density configuration has been shown to yield more power.
