Got my chipped P06 but i converted to Vtec and now it throws code 68 or 69 on 2 different cars one with B16 and other with LSV, and vtec doesnīt engage. I searched for that code but didnīt find anything.

 

It's a ghost code.

Check your wiring, If you are using an OBD1 conversion harness - bingo.

 

Nope, any jumper harness. Could be a bad vtec conversion work?, as a note, the ecu works all around (2 step, limit 9k), but vtec doesnt engage because of that CEL

 

I'd see it every so often, never could make heads or tails of it.

Speed Phreak got it for a while, along with intermittant VTEC troubles IIRC. He had a flaky OBD conversion harness, he replaced it and code + CEL went away. Ask him his $0.02, you could be onto something.

 

when my chips are seated perfect i get that cel and i got it once when the ecu was dirty since i keep my cover off. Try electronic cleaner then dry it off with compressed air from the can not a compresser.

 

hacks

 

lol

 

I've had it before too. I fixed some wiring problems and it went away.(iacv and iat were mixed up)
