Hey, what ecu do i have to use for a JDM ZC dohc Motor OBD1? will a p06 ecu work perfectly without any cel and idling correctly?

also, what timing belt kit do i buy that can fix the dohc zc motor?

Don't know, so ill give you a Bump. Why did you decide to go for a OBD1 DOHC ZC? not hating, just wondering. BUMP

obd1 ls ecu from 94...i have one for sale if you are interested in it

That was going to be my guess, but are you sure the LS ECU is the right ECU for the DOHC ZC or your just saying it cause it will work?

Do not use an OBD1 LS ecu. I tried this with my ZC in my del sol and it ran rich and was sluggish. The timing and fuel maps are for a totally different head design, block displacement, intake manifold and spark plug. Get a P06 ECU, and put in a P29 program. That's a stock OBD-1 ZC program.

When I did my ZC swap into my del sol, I used a P06, then chipped it and put in a stock P29 program. it ran great, and like stock.

edit: My car idled like stock on a P06 and ran OK, although I could tell it wasn't at its optimum performance, and that's when I went ahead and chipped it and put in a ZC program.

Katman says to use a 14400-PK2-004 for the timing belt - 88 Prelude 2.0.

i heard that the pr4 ls ecu will work, but its going to be running rich, trying to find the correct ecu for it where it runs perfectl, i know that there are p29 for it, but its not easy to get ahold of

Ace0246

Correct, however a chipped P06 running a P29 program is alot easier to come by. The LS ecu will never be able to adjust short or long term fuel trims enough to compensate for the difference in displacement, much less the entire difference in the design of the engine - b series vs. d series. Ultimately, you would really be fouling plugs and wasting gas if you went the LS ecu route.

Out of Curiousity, its been 5 years since i had my ZC. But why not a 89 RS integra ECU?

d16singlecammer

An 89 Integra ECU will be OBD0, he has an OBD1 DOHC ZC so that is not going to work.

yea....the pr4 ran a little rich but this was awhile back when ecu chipping wasn't that popular...

i tried both the p06 and pr4...seemed to like the pr4 more
