is there an issue with the speed sensor vs. the mechanical speedometer drive when using an obd1 ecu in an obd0 car? i'm putting a d16z6 from a 95 civic ex into my 91 crx dx. everything i've found on this swap says you can use the obd1 ecu if you want to do a lot of wiring. i like wiring. but none of them mention the speedometer. any help would be appreciated. thanks.

damn i havent a clue. is there a reason you want to go to obd1?

first of all, i spun a bearing, so i need a new motor cheap and quick. i got a good deal on the z6, and it's ready now. i have a dx, so i'd have to swap ecu's no matter what. stupid dual point injection. i'd rather run the ecu for the z6 rather than a vtec switch and a crx si ecu, and the way i'm doing the wiring, it will be really easy to swap in any obd1 b-series later on down the road.

update... screw obd1, i'm running an obd0 pr3 ecu. it'll be interesting to see how it works on the single cam. should be done in a few days. lots of wiring.
