I thought I read somewhere that if I have the MPVI3 I can unlock my own L5P ECM, is that true? I can't freggin' find that information again. I already have the 2 and was going to send it in to be upgraded but if I can't unlock my ECM, then Ill send that in also to be unlocked. Just want to get a definite answer.
Yes via the E41 upgrade kit which can be purchased through resellers that stock them https://www.hptuners.com/product/gm-...m-upgrade-kit/
It doesn't have to be perfect, it just needs to be done in two weeks...
A wise man once said "google it"
If you buy the upgrade kit is it able to unlock multiple ecm's?
