F/IC OVERVIEW The new Fuel/Ignition Controller from AEM Performance Electronics is a powerful tuning tool, designed to allow the addition of forced induction intake systems on normally aspirated, computer controlled race vehicles. By design, the new F/IC is a “piggyback” style ECU that works in conjunction with the factory ECU. Thus, the key to allowing your engine to run at its full potential is making the F/IC work in harmony with the factory ECU. As technology advances, factory ECU’s are getting smarter.
6) FUEL TUNING Factory ECU’s have two running modes Open Loop (ECU does not trim fuel based on feedback from O2 sensors) and Closed Loop (ECU trims fuel based on feedback from O2 sensors). There is no “switch” or magical button on the F/IC that will force the factory ECU to operate in either mode. Open Loop Fuel Tuning Fuel adjustments for open loop running conditions are made in the fuel map. A change in the fuel map will result in a change in AFR.

9) Notes: The basemap file, along with the values and settings it contains, such as the MAF clamp and O2 values, were developed using a stock vehicle. Be sure to visit the video gallery at www.aempower.com for additional tuning tips and information on the methods used to develop the basemap.
