    2011 Camaro LTFT problems

    Hello guys,

    I have tried to tune my friends 2011 camaro but I have faced a problem with the LTFT which is:
    It wont start learning by it self I have to force it to work, and then when I do so it only goes up to 4.7 and stops while the STFT is like 5% or more.

    what could cause this and how to fix it ?

    Your Dynamic Airflow Map/RPM Boundaries are all hosed up. Believe you didn't uncheck the Auto Zone Boundaries box in the BlueCat software main page. To correct will have to go back and start over.

    Is the car stock? Why are you disabling the P0101, 106, 121 and 0068 tests and maxing out Tip In Torque? Why cut Over/Under speed spark adjustments in half? and so on......

    Power Enrichment EQ Ratio is set to 1.07.....gonna hurt something for sure. If you are going to baseline it set to 1.13/1.15.

    Put LTFT Min ECT back to 95, don't want them updating at such a low temp.

    Several others but this is a start.

    Are the O2 sensors operating? Do you have any logs? Post log and associated .cfg file

    What tune file is related to the above logs? Have you straightened out the MAP/RPM zone boundaries yet? Also, you can't possibly have 150+F IAT's, what's up with that?

    When you say force it to learn, what do you mean?

    well my friend told me that some of those ecms after you upload a tune to it the ltft stops all you have to do is take the car for a drive and then turn it off then the ltft will work with you again

    thanks for the help
