Are newer Ford MAF's all 5v Reference

For all other non specifically listed ECU tuning. This would include can-bus ecu's such as powerpc copperhead tricore and siemens ecus. As well as GM, Dodge or any aftermarket controller tuning etc...

Are newer Ford MAF's all 5v Reference

Unread post by cj428mach »

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

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
