1) The LMAF was calibrated for the 42's (not recommended since it skews load scaling) and the flash was programmed with a stock LMAF curve.
DBMSTNG said:it depends on the size LMAF he has. the 90mm is calibrated from the factory for 42's, the 80mm is calibrated for 30's i think.

RedGTvert said:Not sure what you are reading or if it is for the same thing, but Ford Factory MAF's do not have any calibration. All curves are handles by the computer.
