Automotive lingo abbreviation for Fuel Mean value Adaptation (Kraftstoffmengen-Mittelwertadaptation). It corrects injection errors based on MAF modelling and Lambda output.
Bosch EDC16 series offers short and long-term tables of corrected injection errors.
For example:
Requested IQ is 55mg of fuel and translates into 32° of crankshaft ECU checks FMA tables and finds out that last injection event caused excessive smoking and 32° is too much injection duration is corrected down to 31.7° based on historical injection errors
