AEM Engine Management Systems allow for a thorough and optimal tune of your vehicle. For those that only need to modify air/fuel ratios and timing, AEM's fuel / ignition controllers (F/IC) provide PC-programmable tuning for four, six, and eight cylinder vehicles. The F/IC is ODB-II compatible and works in parallel with the factory ECU and is available in Plug-n-Play models for many popular models. Adding much more functionality to the piggyback systems are AEM's programmable engine management systems (EMS). The AEM Universal EMS can be used to tune any race car up to 10 cylinders with AEM's line of precise sensors and connectors. For many popular applications, a Plug-n-Play EMS is available that plugs directly into a vehicle's factory ECU harness and requires no additional wiring or hardware. Regardless if you're vehicle is a mildly modified street car or a full-blow racecar, AEM has a solution for you. Choose AEM for your engine management solution and have full control of your vehicle's tune and make sure your racecar is tuned to run at its maximum capability.
