I installed a greddy turbo kit for a 92-95 civic on my 99 ex and i was just wondering if i should run the p2p ecu with the e-manage or should it be the obd1? Cause whenever i start it, idle goes up and down.. That's with the obd1 to e-manage.. I also checked for boost leaks but there was none.. E-manage is set on 5psi on stock internals.. I'm still on my stock injectors btw if that matters.. Much help would be appreciated. Thanks in advance!

 

get a chipped obd-1 ecu and crome/ectune/nepune tuned by a pro on the dyno.

On a seperate note, your idling funny because you have a vacuum leak.
