No luck errors, cannot flash car now, customer is very upset wants their car back i am at a loss this problem to date has cost me about 30 hours in time and 4 tunes that i could have done but didn't cause i didn't want to mess up another car so total about 2k dollars not to mention the frustration of knowing that I updated the unit causing the problem if i would have left it alone and not updated all would be good still and i would have more money in my pocket.
If anyone knows of a fix or has something to try please pm email call something open to all options.

Thanks paul i will keep that and try it if the problem pops up again.
Well for all who have helped me thank you very much, some how it works now, i flashed it with a tune for a manual trans thinking it might help remove some corupt data in the ecm and of course the car wouldn't even crank no surprise there, but i am not sure if that is what fixed it for sure, i then loaded in an older tune with the old calibration and it worked i kept trying tunes that i had for this calibration and they all worked up untill the date of april 27th 2011 which was right around the time i updated the unit and software, i did this a few times last week and the week before but i never loaded in a different calibration 1st so i am not sure all i know is the problem is better cause i can tune the car still have an issue with connecting with the scanner and flashing from 7.5 but i can work with that. Thank you all who have assisted me the last few weeks if you ever need some thing just pm me.

Ross,

After you do a full flash, use the scantool to edit the VIN... go Bidirectional->Change VIN.

What would cause this
Both of the tunes crank up and idle in park. One of these tunes will not idle if you restart the car, same issue i have had before the problem seems to come back after a while not sure why i only changed minimum idle air you can see in the difference of the tunes, i used a new OS that Ross posted up for me, i loaded it and started to make changes only 1 or 2 at a time then trying to see if any one thing would start this issue to resurface take a look at the two i don't think that change would cause the issue but i am not 100% sure. The tune ending is 0016 works just fine on every restart 0017 will not restart...:sly:
