    You need to strengthen your idle and give the timing some range to save you from a stall. One way to do this is to drop your base timing at idle to around 15 degrees and increase the idle airflow....

    The actual tune file does not get modified while the engine is running. There is just a few learned values that get stored elsewhere in the PCM's memory. So the...

    All good.
    The tune itself cannot change, but there are a few learned values that can mess with you. Disconnecting the battery should reset these, as will reflashing the tune.

    My thoughts are that if it started fine at first without a hiccup, and now has a miss, then there is the possibility that a mechanical failure has occurred.

    Burst knock retard can be used to help with this, as long as there are no other large changes in airflow during the run.

    Check that you are filtering the data correctly before copy/pasting to the tune file.
    Also ensure you are driving the car correctly to maximize the amount of usable data.

    Those tables are for the fuelling portion of the pulsewidth. So if you are showing a minimum pulsewidth in the scanner of 1.5ms with B4003 & B4004 set to 0.85ms you have 0.65ms of offsets added.This...
