i searched in the ecu section found nothing. then asked a question over there nothing. so now ill ask in here. does anyone know how well the safc2 is over the safc1 besides what they advertise. second how well does it work with the stock twins. last i have msd street ported motor intake catback(soon dp and mp) a 255 lph fuel pump and a fuel pressure regulator. the question is will the safc2 be good enough to run my car at 12-13 psi? thanks for any info.

 

Piggy back units aren't worth the money. Either get a remapped Pettit or M2 ECU or get an Apexi Power FC. Save yourself the headache and money in the long run.

 

do u know how much is to remap a m3 ecu

 

UHHHH its not an M3 ecu its a rx-7 ecu that is remaped by a company called M2.... Pettit ecu is better anyways. you can get one of those for about $400-450 used.
