The Air/Fuel Ratio Correction function of the Super AFR allows complete fuel curve tuning by offering eleven points between 650 and 8000 RPM of adjustment. These points can be arbitrarily moved in 50 RPM increments. Each point of adjustment offers a tuning range of 50% rich to 50% lean from the factory baseline setting in 1% increments. Also incorporated in the Super AFR is the Idle Correction function, where Idle fuel mixture can be adjusted from 50% rich to 50% lean from the factory baseline setting in 1% increments within the idle range of 650-1500 RPM. This offers the ability to adjust idle Air/Fuel ratios as modifications progress and require further tuning to compensate. The response function allows for management of engine response in milliseconds with six points of air meter signal adjustment between 650 and 5000 RPM that can be randomly moved in 50-RPM increments. This function is extremely valuable on applications such as high-lift camshafts, larger injectors or bigger turbochargers because of fuel requirements these modifications call for. Additionally, an Electronic Idle Stabilizer (EIDS) function buffers dramatic airflow meter signal fluctuations, preventing engine stalling or stumbling related to sudden imbalances in air/fuel ratio of airflow meter-equipped vehicles using atmosphere venting blow-off valves.
