A P28 runs a D16, not a B16. That would be your problem. It's possible that your engine is a worn out dud, since JDM motors never come with a guarantee. Someone who gave you a wrong ECU might be foolis enough to buy a worn out engine.

from what i've found it's an OBD0 PR3 ECU for 88-91 or you can chip a P28 OBD1 ECU

thanks.. i did use the obd0 pr3 and worked. of course i did have to adjust the timing 1st, cuz until i did that it was still running slow. now i just have to check and see why my vtec isnt hitting.. could it be becuz my cluster is messed up?
