I wont go into details on the story but the laptop shutdown during the first reading of the PCM on my 04.5 LLY.

Now the truck will not start and EFIlive cannot read anything off of the PCM and says it is locked.

I have no idea what to do now. If anyone can help please post or give my cell phone a call (780)499-9985.

Also, is the tranny operating system the same number as the ecm OS? If so, is it possible to upload a stock tune from the library with the same OS and have everything work exactly like it should?

Thanks for any help!

Sean.

try unplugging the batteries for 10 minutes +/-, then try to re-flash

Listen to Larry, this is your best bet.

I think we got something figured out here. We used the relink feature in EFI and it ended up downloading something and I dunno. Fired up after and all works well. Thanks for the responses though!
