going standalone so there’s no need for this guy. It’s an S13 blacktop SR20DET chipped E5 ECU. no, i’m not sure what the chip does. i’ve tried to figure it out, but with no solid result. my car pulled noticeably harder then any other pretty much stock sr i drove though. members on this forum can vouch. i don’t know of many basically stock sr’s running 9psi that could spin 245 rt615’s on heavy 18’s in a 3rd gear brakestand. haha.
i don’t really know what ecu’s go for, price wise. so i’ll just say $150. if that’s a good deal, then it’s my loss and your gain. PM me if you’re interested. located in waterdown.
