Icon3 99 Civic Ex Turbo - idle goes up and down

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!

Emanage. Since you didn't upgrade the fuel system. Hunting idle should prompt you to check the IACV and FITV.

the emanage is tuned for the kit and tuned for the OE fuel system. changing the ecu and tuning isnt going to do much for the 500 needed to change it out.


add a new fuel pump and injectors chip and tune and hes looking at 700-800 bucks
