Good file

[etmotorsports]

I have a 6.7 cummins that has been flashed by something and is not stock, here is the calibration 62351430AZ and the Os is 11620807 if anyone has a good stock file i can use to flash that would be a huge help.

Have you looked on tunefile depot? They have most stock tune available on there web site.

Thanks longcummins the only thing is the calibration number is different, what could be the difference or is that a concern?

[longcummins]

Calibration number isn't important to my understanding its all about the OS # . Its worth a try IMO.

Maybe someone with a little more knowledge will chime in and set us straight.

I know on a GM it typically will change some things like fuel tank size and tire calibrations but since this is just for the engine computer it may not have any affect on the rest of the truck. I wonder what the different calibrations could be for and HO or standard rate engine?

[longcummins]

EFI has no effect on tire size as of yet. I change tire size with my old smarty as in today new set of tires bigger than last set. EFI Live doesn't support that yet.

i believe you thats what it looks like from what i can see just engine controls.

Thanks for the info longcummins and the file.

I have a jtech module to flash ecms i might try to flash the truck and read it but i have never tried to flash a cummins so i am not sure if the mopar site will support it. If it works i will save the stock file and let you know.

[longcummins]

Let me know if that worked for you.
