Hey there, for some reason im having issues trying to tune in 59. its probably something stupid but anyways, im running a 2.0 turbo in a sunbird, 7749 ecm, 3 bar msd map sensor, and code 59.

I upload one of the four base bins. Start it up, and it idles fine....very rich but fine, and on 4 cylinders... They say to adjust the F28 table to get proper idle air fuel... well any adjustment I make it will start misfiring, also, if I leave that alone and try to adjust the idle in the F29X and exact same thing....

I took a quick video to show what I mean...

On stock 58 bin, I can adjust the fuel tables and it changes the a/f ratio just as it should. I don't have a clue what the heck is going on in this 59 setup. I cant do anything.. I already have the timing tables set the same as my stock 58 tune.
