Its possible. If Ross and Paul do decide to have low-speed GMLAN support on the V3, I would definitely like to start working on custom programming for the nav units and all that.
Some of the earlier V2's actually did have the low-speed GMLAN chips on the boards. Then they were removed from later revisions....even the early V2's the chips were never "activated" in the firmware though.
thats true. 2014 seems like last year....... then i remember its 2017 already
BCM tuning is $299
The BCM uses a "TCM" license spot on your V2/Autocal. So as long as you have a free TCM license (most people do), you're good to go. Otherwise, you'll need to buy another VIN license from EFILive.
Is flashing it like anything else, one is advised to first read/extract/whatever the stock file and save it in multiple places so they have it if they ever need to flash it back to stock? Or can it not pull that file off the BCM?
I already thought of that....but no dice.
I tried flashing my 2012 nav unit with Canadian, Mexico, and Middle-eastern calibrations....all of them seem to have video in motion blocked out. I know the parameter IS in there.....I just have to find it the really hard way...ie throwing darts blind-folded.
Maybe other nav units are different and it is as easy as changing the region calibration.....I dont know. Ive only worked with the 2012-2014 style nav unit.
Got a few questions
1. My BCM has been reflash to support OEM heated seats installed after purchase, will that need to be addressed?
2. How is the ECM calibration work when adding high idle if it needs an ECM update? Same for unlimited remote start time. Will I get a new base file that I flash in, copy out and script over with my tunes?
3. Are all the options listed on fleeces site standard or by request?
4. I have an 08 WT 2500 6.0 that didn't have cruise. I added all the necessary buttons and column harness to support it, but GM won't flash the BCM to turn it on, can you enable it?
5. Can you enable the 4wd light to come on in the IC like the manual Tcase trucks get? Hate that it's only the light on the knob.

Hmmmm...good question....can you send me your VIN?
EFILive added the tables into the software, so you can just tweak the settings right in your tune yourself.
Those are the standard options
Yes, can you send me the VIN for that too?
No, unfortunately that is part of the instrument cluster calibration, not the BCM calibration.
Ben
Is it possible to turn the back lighting on for the instrument cluster all the time on an 07 tahoe? The 08 up clusters are on all the time and much easier to see.
it should already have the lighting on constantly.....are you sure the cluster isnt broken???
Ben, sounds like you need to crack the instrument cluster too
Yeah but problem is tune distribution............that was the whole thing with BCM tuning, until EFILive saved the day.
I can already hack the instrument clusters.....but I have to flash them on the bench. No one is going to want to send their cluster out to me, wait for me to flash it, wait for it to be shipped back etc.
