Once you unlock your ECM does it ever lock again? As in if you return your truck to stock will it have to be unlocked again to install a different tuner? The reason I ask is I have a BD on my truck now which I removed the unlock cable after install and I have purchased a MM3 from Ray and if it's not necessary to run the unlock cable permanently through the firewall I would like to avoid it.
Let's ask Ray.Quote:
