No, I havn't messed up my ECM with EFI Live yet! A friend of mine has a LMM with the 100,000 mile warranty and he wants to know if he can get a different ECM to program with a mild tune and if it has to go back to the dealer for service he can put the old ECM back in and not have any warranty problems. I also wouldn't mind finding a spare ECM for my LB7 just in case I have some issue when reflashing. Thank's
