1993 honda prelude si with a auto trans and h23a1 engine. I want a tunable ecu. I am running the stock p14 ecu and it is untuneable so i want to swap to a p06 civic ecu that is tuneable. All the wiring seems the same. I was thinking of using a manual p06 ecu because my car uses a a transmission controller. Will this work if i was to buy and install a s300 hondata and a manual p06 and plug it into my harness?

 

The p06 does not have pinouts for a egr valve so i will be blocking it off with a plate. I intend on boosting so the egr is rendered useless then anyhow.

 

Has anyone ever installed a s300 hondata on a tunable odb1 auto ecu like a auto p06 ecu? If so let me know how it worked out?

 

I havent used s300 itsellf but it will work on a p06 as it will a p28 ECU
