HI, Problem: I need a ECU to run a B20B in my 86 CRX. The engine has all OBD1 sensors so I bought a 94 Integra LS B18 Harness and plan on running the engine on this harness. (Dual-Loom Setup) Question: Hondata says I can run a P74,P75,P06,PR4,P28,P30,P72,P61 ECU. Does it matter if the ECU is out of a Automatic or Manual? I plan on running a manual trans. Any Help is appreciated. -bh
if you get an auto ECU you will need to convert it to manual. You can do it with a pair of pliers in a pinch - not hard. P75 ECUs will run a B20 a lil bit too lean. Get the ECU chipped or get an adjustable FPR and crank it to about 48psi.
