I bought what i thought was a decent running 97' hatch. The PO explain to me that it had a "Mini Me" swap in it. I haven't been around Honda's for a while so I'm not up to date on it. Basically he put a z6 vtec head on the stock block and ran a p28 ecu with a obd2 to obd1 jumper harness to run vtec. It runs decent, just low idle at times plus I don't hear or feel the vtec. I was told that it wouldn't pass smog like that and I would just have to put a dx ecu(p2e) in it. So I got one tonight and the CEL was on and it ran for a long as kept my foot on the pedal. After that it wouldn't start. My code reader said p0450, IACV circuit, and Cylinder Position Sensor. But when I plug the p28 back in it runs as before with no real issue's.

Any help would be deeply appreciated !

It won't run right with the p2e.

No cels with the p28?

Lol off topic but I'm from the h-d to

If it's mini-me swapped, the evap and CPS were probably never installed. The IACV was probably converted from 3 wire to 2 wire. You're going to have one hell of a time getting it running on an OBD-2 ECU, let alone smogging it.

No CEL's with the P28 ! The stock engine is a D16y7, why wouldn't the stock ecu run the engine as is with no vtec ?

Where in the High Desert ? I'm in Victorville near 395hwy and Luna Rd. Maybe you can give me a hand ! All I wanted was a car to go back and forth to work in without having to specail smog it ! I have no plans for mods, rims, etc. Just want o drive it, my project car is a 74' Datsun 260z that I'm dropping a turbo 4.8LS1/6 speed .

The engine is NOT a stock Y7. It's got a Z6 head on it and you will need to run the P28 with it in that configuration. Period. Find a Y7 head.

^ what he said, plus necessary wiring conversion to go back to stock.

Off 395 and Phelan rd in Oak Hills.

Well i decided to fill up this morning and after doing so I swap the ecu to see and the car starts and runs and even idles now. It has a weird idle though like it bounces at a certain rpm.

Still has a code but only 1 for IACV circuit, would that cause the weird idle ? I drove it and its choppy kind of, its either on the gas or off. There's no smooth transition. Don't know if I explained it right !

So you were told you cannot run it correctly with the P2E ECU and you're doing it anyway?

Dc4LsTeG

Yes the iacv could cause your idle problem

Daz-E

Yes, is that not the stock ecu ? P2P doesn't fit !

It is but you don't have a stock motor. Get a y7 head or keep using the p28

What is it that you re not understanding?

Daz-E

Do you have a smog hookup ? I'll just use the p28 for now and get the y7 head later.

No I don't have a smog hookup. My car doesn't have to be smogged

Trying to see if I can locate a head right now, Thanks !
