I'm trying to build a "control pack" for my Godzilla take out motor. Unfortunately Godzilla parts are still harder to come by but Coyote parts are not (Ford MAF pigtail for the Godzilla is like $100). I'm looking at the wiring pinouts for both of them and the Coyote shows a pin thats 12v to the MAF at location 3




The Godzilla MAF plug
Lists
Pin 1- MAF
Pin 2- VREF
Pin 3- MAF Return
Pin 4- IAT

There doesn't appear to be a 12v lead going to the Godzilla MAF. Can you use the Coyote MAF on a Godzilla PCM if you're feeding the Coyote MAF a 12V instead of the VREF? What issues would that cause since the Godzilla PCM is supposed to be sending out a VREF for the MAF and IAT?

Thanks

Mike

read the maf write up

its ground reference -5v not positive

the ecu is expecting a period freuquency input not voltage as the maf electronics does the conversion
