2006 GMC Sierra Duramax. Had to get a new ECM put into the truck because my dad had the dang thing running while he was trying to install and fried the computer so now it has a new original backup. Problem is, my tool still contains the old original backup. Anyway to clear it so that I can get this thing back onto my truck? Tool won't receive any updates until original backup can be installed onto the truck or cleared. I do not want to try to install the old original backup over the new code in the truck with the new ECM; afraid that will cause even more problems.

Anyone have an idea? I need help! Where's the moderator?

fax proof of replacement to 561-908-0048 then call within an hour with the tool powered up so we can unlock it.

What is the proof of replacement? And I have tried calling several times. Nobody ever answers.

hold times can get up there during the middle of the day...

proof of replacement is a copy of the work order from the dealer.
