Which ECU for a b16a2 in a '93 si?
Hi guys, do any of you know which ECU to use for a b16a2 in a '93 si? To make things short, I acquired the car from a friend who wasn't able to complete the car due to ISF. The car was sitting around for a year doing nothing so I just took it off his hands. The wiring is all screwed up and it looks like the stock ECU is in there. I'm told only a 94-95 GSR ecu will work. Will any others work and does anyone know where to acquire one?

The correct ECU would be a obd-1 p30 or obd-1 pr3 ECU, It's what i'm using with my b16. You can also use a chipped p28. I have a jdm b16 obd-1 pr3 for sale if your interested

OBDI PR3 JDM
OBDI P30 JDM or USDM
OBDI P72 USDM or JDM (not really recommended)
OBDI P61 USDM (from 1.7 GSR, pretty good ECU very simliar in mapping to P30)
or
chipped P28, P08
