Yeah I recently installed a dohc zc into my EF and I made the wire harness myself, and I got all the pin-outs right (checked and re-checked with test-light, very pain-staking!).
For a while I was running on a PR4, I had a few check engine codes, and fixed them all. I have a PM6 beating around the house and when I plugged it in, I got some codes, so I just thought maybe that computer cant run a ZC. So I ordered myself a PG7 (stamped 1988 my motor is a 1991), so all should be fine. I took an injector resistor box from a 1990 integra, and yes everything is hooked up right.
I am running a code 4, and a code 20 on my ECU and the car is crapping out a 3200 RPM But as I said, with the PR4 it didnt, but with the PR4 the car was bogging out violently under 3500 rpm when the temp. got to its normal place....

Can anybody help me?!?!?! If so please leave a message, or a link, or just something! I want to slap a turbo on that little F***ER but I have to take care of that stuff first......PS I got a new cap-rotor, plugs and wiring. And yes the right ones lol.

Thanks- a very desperate ZC lover.
