Question. I have a 3 Bar speed density tune loaded into my PCM and have had my car tuned with a separate PCM using EFI Live and a 'roadrunner'. After the tuning was done we tried to load the tune into my PCM which already has a HP Tuners 3 bar speed density tune in it and the files wouldn't go. There appears to be a confilct that will not allow EFI Live to load the tune.

I have tried to re-flash my PCM loaded with the HP Tuners 3 bar speed density tune back to a stock calibration with my GM Tech II and Service Programming System from TIS but half way through the process the GM software identifies an unknown 'operating system' and stops the process generating an error message, E2906 saying to contact customer support.

I believe it can't overwrite the HP Tuners 3 bar operating system.

Has anyone experienced this conflict? Any ideas?

Have you tried rewriting your ecm with the stock os using HP Tuners instead of a Tech II?

You would need to have someone with hptuners flash you back to a stock operating system then write over it with efi's 3 bar.

If all else fails, give Jess @ wait4me a call.

Stupid ?

I have HP Tuners and the calibration I ran with my H/C set-up using a stock MAF before I went with boost and a 3 bar SD tune. Can I re-flash my PCM with this to cure my problem so that I can then load the EFI 3 bar?

Thanks!

You would need flash in a stock operating system using hptuners then write over it with efi's 3 bar.

Where can I get the stock operating system files?

You could probably grab one from our repository if you don't have the original file from your vehicle.

Thank you, I understand now. So I should be able to load my last tune from my h/c LS1 to accomplish what I need to do which was done on the stock operating system.

I don't need to run the car with this, only format the PCM to accept the EFI Live tune, or perhaps write over with the Tech II/TIS software to get a total OEM stock program for starters, then load the EFI Live 3 bar. Correct?

Correct, you just need to flash in a stock OS since most of our custom operating systems are OSmod locked.

Once you have a stock OS installed you should be able to read it out with any other software package without issue.

Thanks, worked great!

I am such a rookie when it comes to this stuff, but I am learning
