Stealth MAF's are Karman vortex types. They have a vortex generator and a pressure transducer and an A/D converter. The vortex generator makes little whirlwinds in numbers proportional to mass air flow. The more vortexes, the greater the frequency of the pressure pulses on the transducer, which outputs a sine wave a/c output to the A/D, which turns it into a square wave digital output with the same freq. and sends it to the ecu as a digital freq. Don't know how the ecu processes it for lookup. (I just found the Stealth Technical Manual ftm .pdf)

MS2 has the ability to control spark, and will run a Ford EDIS just fine, and you can forget the maf matching.

KISS and speed density are my systems....
