I'm having trouble getting my ECU to take a tune! Its a chipped PO6 out of a dx i used to own. and it was running with working vtech before with a stock P28 tune. NO CEL CODES

Symptoms with now installed turbo setup are very rich when in vacuum, like 9:1 ....10:1 AFR's and we can't get the o2 sensor turned off.

So it is giving us codes 41 (oxygen sensor heater) and 3 (map sensor)

what can i check? Do? Is there something we could have missed in chrome?, my bud dvst8r was helping me but we only had a couple hours cause i had to drive home.

You really haven't asked much, so I'm not sure what kind of answer you want.

Not to mention you have a "shocker" sticker on your car.

Other than the newly installed turbosetup, its a completely stock 92 civic SI.

I was on the couch in between puking my guts out because of the flu and without taking time off work. blablababla

Found stock o2 and managed to clean up th threads enough to get it to stay in. runs much better all warmed up now! cold loop is still crazy rich but not a big deal. Gives solid CEL when going into boost....(((code 3 map sensor)))) going to try an bolt on another map sensor tonight and see if it goes away.

While I'm getting the car to run with the tune we put on my spare chip, "beerbongskickass", still doesn't explain why the car wouldn't take the first dozain tunes we tried. (we tried turning off the o2 in all tries).

Thanks guys will post pics when i get around to it, or maybe when i'm doing the clutch.

I put in a new map sensor last night and I still get a bad hesitation (feels like rev limit/ spark being shut off) on tip into boost. If i floor it as this happens it feels like the motor is shut off (similar to a top speed governor) and the CEL comes on when it goes into boost too.

Any suggestions please feel free to shout em out,

My car does the same ---- on occasion, I believe it's TPS.

rev lim/speed gov is fuel cut.
