    Fuel trims are all 0's and the O2's are stuck at 450. ECT reads 192.

    Fift5, we would love to help but need a bit more information.


    • What vehicle
    • What modifications
    • Have you made any mechanical changes
    • When did this problem start (i.e. after a cam / intake / etc. swap)
    • Have you checked for vacuum leaks (a tune shouldn't be used to mask mechanical problems)
    • Upload your file and a log so we can see what you see


    This information will get people interested and thinking which may lead to answers.

    the motor is from a 06 chevy truck, the computer is from a 01 camero i believe , i was told that there is bigger injectors , it is a stock motor , no headers , running manifolds, when it was first tuned i was told that the front o2 didnt work for some reason ,so i traced the wires down and checked with ohms, they checked out that way and when i got the HPtuner i turned them on and they seem to be working , all this is in my 55 chevy ,, here is the file hope i done this right
