    Default Help with LTFT please

    Hello everyone.

    My LTFT's don't seem right, LTFT1 will be anywhere from 1-4% above LTFT2, and some trims on LTFT1 are + and trims on LTFT2 are -. Any ideas?

    With the stock tune, there is still a 1-4% seperation.

    Thanks.

    Could one O2 sensor be reading slightly different to the other? Maybe try swapping the sensors over to see if the problem reverses.

    I have seen 1 to 4% off from side to side many times. Sometimes you can replace the O2's but I do not think this wold be a problem being different by a few percent.
    Now if you are off by 10% that is another story.
