Series 2 Plug & Play EMS. Manual Trans. SUBARU: 05-06 Impreza WRX STi
AEM's Series 2 EMS is a complete engine control system that plugs into the factory harness and uses the factory sensors. This means you do not need to replace any parts of the harness or sensors, just plug the EMS into the harness and begin tuning! The Series 2 EMS for the Subaru WRX allows you to control every aspect of your EJ25 from cam control to rev limit, timing, bigger injectors, boost control, nitrous injection, and individual cylinder fuel and timing trims. For drag racers there's even anti-lag! Professional tuners will appreciate the ease of use and security features on AEMTuner, the interface software for all Series 2 EMS systems.
