can anyone tell me why my car idles like a wrx when i have obd2-obd1 conversion hooked up with an obd1 PO6 ecu?? if it ran like a wrx, i wouldn't mind, but it runs like complete butt... so if anyone can help me out with this situation, i'd be highly appreciative.

my setup: 98 ek hatch, b18 ls engine, gsr tranny, obd2 ls dizzy, obd2 civic injectors, stock wiring harness. i have done the 3-wire to 2-wire iacv, and ckf sensor tricks.

will run good on my obd2 civic ecu, but i know it's not getting the power it should with it.
