Bootloader Error

[Cougar281]

Anyone with a braindead (in the same way Johnboy's is braindead) LB7 ECM want to send it my way for "tinkering"? When done, I could pull the chip and send it to Ross for analasys if he wanted.

I am trying to get another ECM for that truck.

I would really like to send it out.

I have 2 ECM's doing this same thing to me. One had a dealer reflash done while it was tuned in an 02 LB7. The other is a 01 LB7 that I tuned a long time ago with the 01 LB7 OS...and it has not been touched since I tuned it a year ago. Both act the same as Johnboy's.

To anyone and everyone that can reproduce the problem described in this thread:

Can you please locate the file:
\My Documents\EFILive\V7.5\Bug Reports\Upload_YYYYMMDD_HHMMSS.blx
where:
YYYYMMDD is the year, month and day
and:
HHMMSS is the hour, minute and second
that you attempted to read the controller.

Please send that file to me at paul@efilive.com and
include a link to this thread so that I can correlate
your file with this message.

I may be able to piece together what is happening if I get enough trace files.

Regards
Paul

Bobo, your PCM is sending back a response indicating the PCM is not locked, but it appears to be locked. By locked I mean just with GM's standard key - not a custom/user defined lock. That means EFILive will not send the key to unlock the PCM. Because it really is locked, EFILive will never unlock it and reading/flashing cannot continue. I will see if I can make a change to allow you to force EFILive to unlock the controller even if the controller "claims" that it is not locked.

Edit: Ignore this post John, I mixed up your trace file with someone else's - your trace file shows everything worked ok - is that the case?
Johnboy, your trace file shows that your ECM is possibly brain dead and EFILive is incorrectly identifying the TCM as the ECM. That is a known bug in V7.5.1.

Try upgrading to V7.5.3 here:

or even the V7.5.4 beta software, here:

Note: you can run the V7.5.4 beta software on your existing FlashScan cable without having to upgrade to the FlashScan beta firmware.

After looking at the date again I beleive the file I sent you was for an 02 that I recently did. I flashed it after I had the issue with the bootloader error. The 02 flashed just fine. I will email you what I beleive is the correct .blx file.

Thanks for the help, Paul. I just sent you more mail. We are making progress. I was able to upload the ECM tonight with your help.
