u7146 opps!... and question

[brettlaw83]

i just bought a mustang and i came with a predator,,
it has the current firmware because i updated it and even on a stock tune the readiness test will not change for the o2 and cat from incomplete..
i understand the older firmware allowed you to cut o2 on and off and current doesn't....
basically i need to have my o2's turned back on for emissions ....


any way to downgrade to older firmware or a way to change a custom tune to simply cut o2 on? i have mil eliminators i just need them on for emissions!!???

well, we cant edit the stock tune, so if they are off there somehow, you have a problem.

If it is not passing stock, its more likely another issue, as opposed to the tune itself...

Is there a way I can upload the original back up and check weather rear o2's are in fact turned on or off?

I had a similar issue with previous Mustang where the o2s were disabled before the tuner was added and got an email tune with them cut on

Thanks alot for checking!
Now when I used Downloader to send you that file, which tune did it pull from tuner? Like was that the backup, current, or custom?
