Background Info:
The SAFC is a piggy back computer that modifies the MAP Sensor (Manifold Absolute Pressure) signal to the PCM (a.k.a. ECU) of the car. This is really useful because it can "lie" to the car’s PCM about how much air it is getting. Accordingly the PCM will give more or less fuel to the engine, thus helping you tune. Added use of the SAFC comes from the fact that you can play with the settings throughout the RPM range with different throttle positions.
