For the people that have swapped an H22 into their 96 or newer Accords, were you able to run the factory ECU and have the engine work without and CEL light? I'm thinking of doing the swap on my 97 but I live in VA where there is a plug in emissions test where they plug it into the OBDII port, if you don't have a CEL light on it passes.

Any help or info you guys have on this would be appreciated, thanks.

 

We have a plug in emissions test? You must be Northern VA... I think they do.

You need the OBDII P13 ecu - only one that's OBDII without an immobilizer. If you run an OBDI ECU you won't have a CEL (if everything is fine) but the OBDII port will report no communication - that was enough for the buyer of my car to register in Arizona (similar testing).

I'd imagine running the stock ecu would run you in limp mode but I"m unsure on having a CEL.

 

1996 honda prelude vtec ecu is what you need. it is the ONLY obd2 p13 and the immobilizer was on the 97+ ecu. its a very rare ecu.

 

ya,what they said...i actually got lucky and found one on craigslist for $200 from this chick...

 

would it pass with a 96 p14 ecu, granted it wont have vtec but just curious b/c i found one on craigslist for $50.
