Fuel & Ignition universal piggyback ecu.
The AEM Fuel Ignition Controller is an economical solution for controlling fuel and ignition on vehicles that do not require stand-alone engine management, including variable cam timing engines like VTEC, VVTi and MiVEC.
Overview The Fuel Ignition Controller is a PC programmable unit that gives users with OBD-II 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forced induction systems the ability to retard ignition and deliver accurate amounts of fuel without the need for outdated FMUs or ”boost hiding” controllers.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 and will not cause a check engine light (CEL).
Precise Fuel Delivery
The Fuel Ignition Controller intercepts the signal to the stock injectors, allowing the user to modify pulse-width by +/-100%. The F/IC is the only piggy-back system 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.
Timing Retard Control
The Fuel Ignition Controller has the ability to retard timing 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 Fuel Ignition Controller can retard timing from the factory system based on engine RPM and load inputs.
Sensor Calibration and Control
The Fuel Ignition Controller 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 applications. CAN-BUS SYSTEMS NOT AFFECTED
Since the Fuel Ignition Controller 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.
