It’s right there, version 2.0 and up which is you. I remember reading up on his product when I was looking at buying the Autosync and opted to flash the BCM with my Autocal instead so I’m familiar with the instructions. His seemed less confusing than Autocal’s instructions which make my head spin. When you go the instructions page it lists the version numbers. It says the new version is significantly different from the old ones.

BCM flash is likely still in my future.

Supposedly with the AutoSync flashing is pretty easy. You purchase the BCM flash online with the options you want changed and they make the AutoSync download it over the internet the next time it connects and once downloaded you just use the menu options to flash the BCM.

Yep, Ben Tyler, the guy who created the AutoSync and figured out how to flash the GM BCM’s, is a friggin genius imo. He also was a co-creator of the EFI Live Autocal but branched out on his own and created BT Dieselworks and his own line of products. The Autocal is complicated as far as doing a BCM flash, I don’t think it was meant to do that but he made it work. It seems like the AutoSync was created with this in mind, it deals with things other than tuning the ECM’s and TCM’s , it just does BCM functions so it doesn’t have all that other crap to wade through. It took a minor miracle I felt like in order to use the Autocal to do a BCM flash. He figured a way to make it work so he could sell the BCM flash to guys who already had money invested in an Autocal but it is definitely not a walk in the park, and I had flashed several tunes with the Autocal fairly easily. I felt like the Autocal was designed for tunes and the AutoSync was designed for BCM’s.

OK, after long awaited rebuild with trans and fuel lines finally completed. I picked up my Hoe, while down in Florida, over the Holidays. Upon driving back, I blew both the front and rear main seals...and guess how F'ing PISSED I WAS!?!
Anyway, now that these are fixed, we have finally figured out why and what needs to be corrected!! I recently had foot surgery, so she's sitting out in the driveway, collecting nasty yellow pollen...but i wanted to include a pic of the engine bay, so yall could finally see the finished product with the Maggy supercharger.
I left her in Florida, when I moved up to NC, and she got a new 3" exhaust, all new trans and fuel lines, new fuel pump and dyno tested. I had the engine completed, just needed to the flex lines run, pcm reprogrammed, and exhaust. With the dyno testing completed, my guy failed ot tell me, we needed to add a crankcase breather. That's why the seals blew!

Anyway, here she is, and I have some more exterior work, I have to get done, i.e. new drivers side mirror, and Install escalade rack, etc.View attachment 394016View attachment 394017View attachment 394018View attachment 394020View attachment 394021

I was starting to think this build was made up. :bleh: Congrats on finally repossessing it!

Why was the A/C compressor relocated?

AUTOSYNC!

did it to KILL the auto doorlocks! (set them to lock at 300km/h)

A huge *THANK YOU* to -TYF- and whoever else posted about the Autosync. This forum is how I found it.

Auto rear windows worked for me. When you tap the window button.. it goes - stops - then auto goes again.

I'm new and my first 3 posts have all been about autosync. Not affiliated in any way other than being a satisfied customer.
It should be stickied considering the lack of other BCM programming options (?) and the number of threads on here asking for it..

3rd row seat color change.

Recovered the seats in black a few months back, but that left all of the beige plastic and belts. Tore it down to the shell and replaced everything that was beige.

The first seat took a while, mostly due to those pesky bolts holding the interior/inner trim pieces. They are hard to get to. Everything else is pretty easy. 2nd seat went a lot faster - I just took off all of the outside trims, then the seat covers then removed those interior/inner trim pieces. Lots more room to work with and much easier.
