Sorry to hear about the bad luck Bob.

That works out PERFECT!


I have no patience, and I don't lock tunes.

I get the same bug, but I can usually force it via the turning the highspeed off, and reconnecting everything.

Hi i read this thread and i am new to the forum. I have been in the diesel place forum for over a year now. I am having the exact same problem with my 2002 LB7. I am stumped. Please help!

Is this the same vehicle we have been dealing with on Diesel Place?

Cheers,

Yes i thought maybe someone might see it here that isnt part of diesel place. Well i checked the EFI LIVE forum last night and someone else had the same problem as me. On of the replies said to enter F$$$$ in the keys spot above alt keys. That would let me upload the current settings but not let me flash. I tried the alt keys and no high speed but it did nothing. ive reflashed the truck maybe 20 times over the last year and im really good at remembering numbers. I was sure i saw the seed # was $2333. I tried it and, IT WORKED!!! I cant believe i remembered the seed number! I havent reflashed in 3 months! There have been a few people with the same problem. Some of them bought new ECM s. I wish they would have written down the seed number. It seems like the ECM forgot or lost the seed number. But when put in manually it works. I would urge any LB7 owners to record the seed number from their truck... one day it might save your a**! Thanks for all your help from everyone on here. This was the first time i posted a problem. This was very helpful. Now i have to go try and help a couple people that are stuck like i was.

PS. I did upgrade to the latest version of EFI LIVE last night, dont know if that helped any.

The 2001/2002 Duramax ECM has a habit of losing data, not all the time, but it happens, it's even worse when you let TechII near it, I am impressed you remembered the key!

I have had this issue the last week. Paul from efilive sorted me out quick smart.
Because the pcm had failed to flash completely it did a recovery flash and locked the PCM automatically.
All i had to do was put the seed number in as the key and it unlocked the computer.

Cheers to EFILIVE support for their help.
