AEM Fuel/Ignition Controller 8 for 8 Cylinder Aftermarket Boosted Vehicles



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 It enables racers to retard ignition timing and deliver accurate amounts of fuel without the need for outdated FMUs or “boost hiding” controllers.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.

  • Ideal for non-factory forced induction vehicles with variable cam timing (VTEC, VVTi, MiVEC, etc)
  • Will not affect climate controls, dash or other components on CAN-bus network
  • USB powered for calibration changes when removed from vehicle
  • On-board 41 PSIA (25 PSI boost) MAP sensor
  • 2Mb Internal data logging





    The F/IC-8 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 eight (8) 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 effect 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.
