Does anyone know if the tune will void warranty from dealer?
I found this from Mat, the OVTune dude.
Just an update, the tune being indetectable is incorrect. The older versions of the tune we're undetectable (1.02, 1.03, 1.04, 1.04r), but the newest release (1.05) will be detectable by the dealership.
To create the newest release of 1.05, Mat had to modfy the shift and engine management tables enormously. He stated in the last few days on the TW thread that due to such an enormous changes in the management that he decided to change the way the ECU and TCU identify themselves when hooked up to a scanner. The flashed ECU and TCU used to identify themselves the same as the factory tune. Now with 1.05 they will not, therefore he is now recommending users flash to stock anytime they go to the dealer for warranty work etc.
The official IDs for 1.05 will be as follows:
"OVT" ---- tune
"1-05" ---- version
"93" ------octane version
Thanks

A user then questioned why the change.
You know that with the previous revisions the calibration ID would stay the same, even OVtune would say that there was no need to flash back when taking the truck to the dealership, now he changed the calibration ID and he's recommending that we flash back before going to the dealership, I just wonder why he's doing it differently now with 1.05
The reason is because we have custom patched the ROM, as a result the code and tables are significantly different, so we want to designate it this way.
And then another user then questions if you were already chaging the code before, what's different now that required a different designation.
This was before we modified hardcode (not just data sections) but actual code / lookup addresses / modified sections of memory, how the processor allocates table size in memory, etc.
