So ive fitted a b16b from a prefacelift ek9 into my facelift em1, the engine came.with a loom and p30 ecu mapped on chrome, i didnt use the.preface loom and purchased an obd2b to obd1 conversion harness, evrything fitted and it doest start, starter motor turns, injectors prime and fuel pump works but it doesnt fire up, but if i remove the p30 and fit the p2t from my b16a2 it starts and runs great, any help??
 
sounds like a immobiliser issue, or there was something on the b16b engine loom that the ECU was mapped for? but im pretty sure its to do with the loom
