My daily driver spun a bearing so I found a junkyard motor to replace it.
The original was a d16y5 vtec-e 5-spd motor with a p2n ecu. I used the original wiring harness from the car. The d16z6 was out of an auto. I have the p28 auto ecu.

What ecu should I run? Will the p2n work? Would the p28 auto work with a conversion harness? What about a p2p out of a 96+ civic. The 'new' motor is in the car waiting on fluids, and a distributor plug harness from rywire.

 

you need a manual p28 and a conversion harness. you could run the y8 ecu but it will throw some cels for sensors not forund on obd1 motors

 

Any idea what codes the p2p would throw? I want to do this as cheap as possible. I hate putting money in my POS daily driver!!

Looks like I'm going to have a couple ecu's for sale..

 

I received my distributor plug adaptor from rywire this evening, and decided to see how the car would act on the original p2n ecu.

It fired right up! A quick test drive felt solid. No noticible misfires, etc..

So, here's my question:
Would I have long-term issues just sticking with the p2n ecu? I don't care if I have a cel. I ran with a secondary 02 cel for close to 2 years. Remeber this is my daily driver/beater! It just needs to get me back and forth to work.
