hello all,
long story short is that my truck was tuned 3 or 4 years ago with either efi live or hp tuners, not sure which.
fast forward 4 years and i have efi live, just went to go upload a tune and my ecm is locked by the previous tuner. how in gods green earth do i unlock it so that i can tune my truck? i have no contact to the previous tuner. Is it possible to get it unlocked, or do i pretty much need a new ecm?
if i need a new ecm, will anything in my tune need changing, or simply swap it in and reflash with my tunes settings?
fyi its a 1999 gmc sierra, with a lq9 engine swap
