Can you read a PCM that was programmed with EFI Live?

[yrkz06]

I need a PCM for a LBZ to LB7 swap that I am doing and I found a decent deal on one but it is already tuned with EFI Live.

Can I read this with HP Tuners or is it locked?

Anyone have any experience with this?

[Bill@HPTuners]

Could go either way, if its a custom operating system our software might be able to read it but likely won't be able to open the file.

Thanks Bill!
I'm guessing worst case if I can't read it I can do a write entire with stock software and go from there?

[Bill@HPTuners]

Worst case would be a tunerlocked pcm which cannot be read or written to not even by a gm dealer flash tool.

Huh thats good to know. I always thought any PCM could be over-written with a write-entire as long as it was in working condition.

[Bill@HPTuners]

Tunerlocked means its locked, no read no write.

Thanks Bill

I currently have an EDGE EVO RACE tuner. I have changed the tune in several different levels with HP TUNERS. Can I just set the EDGE on level 1 and use HP tuners to change to different tune levels and still plug the EDGE back in to monitor functions?
Thanks

Yes you can use the Edge as a monitor only and make your tuning changes with HPT.
