IN the end, it runs without any timing being pulled as before at part throttle. no clue why.
NOW....im curious, so i went back to one of my recent tunes that had the timing problem. then i compared and copied over stuff little by little. flashed them in a couple changes at a time until it all basically matches again. CANT get rid of the timing being pulled at steady throttle off idle.
I can then flash the other file back in , and its fine again. go back to this one, and the problem is back. theres only a few little things left that are different between them, but they shouldnt have any effect ,like cranking fuel, and idle adders, etc. makes no damn sense.
