I?m new to this and I have a rtd device and probably a locked tune. If I get a mpvi3 will I be able to see what has been done if I download the tune from my car. Im not looking to change or do anything other than see/know what has been enabled/disabled or what set points are for things like o2, misfire, afr etc.
Purely for my own knowledge and maybe piece of mind.
Negative ghost rider, the lock is there on all HPT devicesQuote:

RTD is a scam. Lock whole time
Is there a way to unscramble the OS? Maybe with Hex editor?
I mean if you know what car its from you can narrow down the list of potential OS's significantly, if you have a hex editor, you could take an unscrambled file and see where the OS name is stored. Then it would be a game of chance just trying OS ID's that you've found.Quote:

Cant speak for Fords but on GM and Dodge if you do a new read with the MPVI it will pull the file with no issues.
