    AIR/SMOG eliminate $6E edit?

    ok Mark i tried using the AIR pump enable temp in the V1.2 XDF file you made up and gave to me, first off it only allows to go up to 151.25*f and even if i set it at that when i go to burn a chip it either just says it didnt program or it programs but doesnt verify so somethings off there(tested chip with other bins and n/p even tried diff chip).
    p.s. i have read that some bins actually do change the O2 sensor by like 100mv when pumps active to manifold but not really sure if thats in the deverted state or non diverted, not even possitive if the $6e is included or not but would be better to be safe and cover that base if possible.

    here is the code info i have found on air pump diversion for $6E.. doesnt mean a thing to me as i dont know anything about the code/deffs/or anything hidden in them and not defined in simple form right on my tunerpro screen lol..but thought maybe you could make something of it.

    The 151.25 is correct in Celsius, it's just an XDF error when I made it. Now we have found issues with some of these temps before do to it being through a 1k pickup which uses an inverted table... which means slide the slider all the way to coldest temp and see if that turns it off!

    Not sure on the rest...

    ok update time..
    i havent tried setting to coldest yet but instead decided to try and edit the HEX directly... now from my reading i have read that it is located at address 0324 so i look there and it has a 49 there instructions say to make it FF which i did but when i burnt the chip all went fine and as before it said chip programmed but didnt verify just as before. hmm

    Sounds like a programmer/chip issue, not hex change?

    OK, that's weird... are you using TunerPro? Make change and save bin so checksum is corrected? Not even sure the programmer cares?

    Try to change it to FD.

    FD is almost maxed out temp. We found some issues with using max in some instances. I don't go max on anything since then. 00 is low end and FF is high end. These are also used as filler...
