The F/IC gives users with OBD-II race vehicles and non-factory forced induction systems the ability to retard ignition and deliver accurate amounts of fuel without the need for outdated FMUs or “boost hiding” controllers. This system works parallel to the factory ECU preventing tuning limitations due to complex factory timing patterns. 21x17 maps with configurable load and RPM breakpoints are easily accessed with the F/IC's Windows-based tuning software. The F/IC draws power from PC USB interface for quick and easy calibration changes. The F/IC intercepts the signal to the stock injectors, allowing the user to modify pulse-width by +/-100%. The F/IC is among the only piggy-back systems that can decrease injector pulse-width, allowing the user to drive larger aftermarket injectors* while still maintaining proper air / fuel ratios. This powerful system can also tap into the factory injector signal and work independently to drive up to six (6) additional injectors. The F/IC can retard timing from the factory system based on engine RPM and load inputs. This is achieved by intercepting and delaying the outputs from the cam and crank position sensors to the engine- with no adverse affect on applications equipped with variable cam timing. The F/IC can also be used to recalibrate / clamp the MAF sensor, eliminating common problems with non-boosted factory MAFs. The on-board MAP sensor allows for proper fueling in boosted conditions. Since the F/IC works in conjunction with the factory ECU, late model-vehicles equipped with a CAN-BUS system retain functionality of climate controls, dash and other components on the network.

The AEM Fuel / Ignition Controller is designed to work with nearly any ECU, except those using frequency-based MAF sensors. The F/IC must be wired correctly for it to function properly.
