AEM’s FIC  is a PC-programmable piggy back controller that allows users to retard timing and add fuel to virtually any 4 and 6 cylinder engine - even on variable cam timing engines (VTEC, iVTEC, VVTi, MiVEC, etc). The FIC works in parallel with the factory ECU and allows vehicles with CAN-BUS to retain the full functionality of the climate controls, cruise control, dash, and other components of the network.

If you have boosted your factory engine, or plan to in the future, the AEM FIC is an affordable alternative to a stand alone engine management system that still allows for powerful tuning. The FIC can work with either factory or larger aftermarket injectors, and can even clamp a factory MAF so you can run boost with your stock mass air flow sensor. This allows someone with an OBD-II vehicle to easily and safely add a turbo or supercharger to their vehicle yet still maintain every day driveability.
