Unable To Upgrade E40 OS

[LFSADRG]

2005 Pontiac GTO M6
HPTuners 3.0.96

Attempted to upgrade to the 2bar OS but keep receiving a prompt when trying to write, "write calibration selected for E40 but operating system ID's are different".

Followed the instructions but same situation:
https://www.hptuners.com/help/vcm_ed...ters_gm_os.htm

What I have found is that I think that I need to flash back to the original stock tune but I do not have it. Found an original stock tune from the repository. From what I understand if I were to flash a downloaded stock tune from another car it may brick the PCM. Also, that I would need to purchase two more credits.

The car has been tuned throughout the years by Diablosport and then using HPTuners from other folks who do tuning so getting THE factory stock tune for my particular car is nonexistent. I am now taking the reigns and learning for myself using The Tuning School and forums.

So my questions are how do I restore the car back to the factory tune by not using a TechII and then upgrade to the 2bar OS? Is installing the stock tune necessary? Once I upgrade the OS can I flash my original modified tune?

Thanks in advance.

Will do, thanks.

Any update to this issue? I'm having the same problem.

[LFSADRG]

Had to use ver 2.4 to upgrade the OS.

[Bill@HPTuners]

Thats odd, there is no 2.4 version never has been.

Additionally its odd support would tell you to go backwards in versions, I'd be curious to take a look at your ticket. What is your ticket number you submitted to support so I can review your correspondence?

[LFSADRG]

My bad typo, 2.24. My previous ticket was Ticket ID: 35827.

[Bill@HPTuners]

Sounds like you need to update your software LFSADRG that ticket sounds like its from 2016 and no longer applies to this thread.
