1g ecu in a 2g
« on: March 09, 2012, 07:15:04 PM »
OK since i started my 2g project, Im having issues finding any means of tuning even close to being affordable(link) or easy(evo8,h8)) or even available(evo8,h8) but I have found people who have made harnesses for 1g ecu's in 2g's  like this


I have tried to contact them but they seem tight lipped.. So i started doing research and have just about every pin swap figured out. I do have a few that maybe someone here can help me.. since when this subject is asked in any other forum they just say "get link"

pins 63 and 66 on the 1gecu are mpi control relay...can I feed them with pin 38 (mpi relay poer supply) from the 2g harness.

Yes 63 and 38 are ground outputs to kick the mfi.
Pin 66 is a +12v input for mfi verification.



You guys know these go right into miata's too, right?
