AEM Fuel/Ignition Controller Bypass Harness DISCONTINUED 35-2911

Ignition Controller Bypass Harness by AEM®. With Bypass Harness. AEM’s F/IC-8 is a piggyback engine control unit that works in parallel with the factory ECU. It enables racers to retard ignition timing and deliver accurate amounts of fuel without the need for outdated FMUs or “boost hiding” controllers. This system works on OBD-II-equipped race vehicles with non-factory forced induction systems with or without variable cam timing and prevents tuning limitations due to complex factory timing patterns. The F/IC uses a vehicle’s factory base map to create calibrations via a powered USB connection to a PC, so drivability and cold start are not affected. Since the F/IC modifies the factory timing patterns it is not necessary to know them in advance. The F/IC can also recalibrate sensors so users can add a MAP sensor for boost without affecting the signal to the ECU. Since the F/IC is a trim device it will not cause the factory ECU to throw a “check engine” light because it allows the user to intercept and modify the cam and crank inputs. Additional injector drivers allow users to control up to six additional injectors for high-horsepower vehicles. And it works on variable cam timing engines.
