I'm looking for any feedback on EFI Live or any other reliable Gen 3 GM tuning software on the market.
I have a 2003 Cadilliac Escalade 11:1 LQ9 Ported Heads, Cams, Injectors, Headers blah blah blah dead in my driveway for the third time this year. I keep getting a "controller unlocker timed out" error. It appears to be a problem since atleast 2016 although it has only been a thorn in my side since fall of 2019.
MPVI2 Latest software, freshly synced, tried two USB Cables.
Disconnected Battery. Yup until I was afraid of wearing out the threads.
Pulled fuses. Yes all of the recommended ones to the point I barely need to read the fuse box cover for location.(And the one in the side of the dash).
High Speed/Low speed. pssshh doesn't matter Controller Unlocker Timed Out is the end result.
Help Desk Tickets. Yes quantity of two. I'd rather off this thing then do a third and get good tuning software that won't leave me stranded.
The only thing that seems to work is letting the battery die until the point I have to reprogram my key fobs.Then it will finally write.
I'm not concerned with the cost of new reliable software that flat out works. I'm looking for anyone that has a better experience with other software.
My original thought process was, getting HP Tuners was cheaper then hitting a tuner repeatedly through the phases of the build would be cheaper then the professional tuner costs. I didn't expect to be dead in the water 3 times on my daily driver due to software issues. Although It has probably taken about ~20-30 tunes thus far.
Does EFI Live or any other Tuning Software have these issues?
