Anyone have experience using GM's ACDelco TDS (Technical Delivery System) and their Service Programming System (SPS2)? Now that I'm out of warranty I'm thinking about getting all the modules in my 2021 GMC Canyon programmed with the latest and greatest. I've got a couple annoying glitches in the infotainment system and the DIC and I wouldn't mind getting the latest transmission/engine programming.
Option 1 - Take the truck to the dealer and let them do it. They have been awfully vague on how long it will take. Probably at least a couple hours but it could be a whole day, it really depends on which modules are in need of updates and how long it takes.
Option 2 - Get a subscription to ACDelco TDS ($45/year) to get access to the latest files and buy a cheapo J2534 OBDII programming device ($100-150) and do it all myself.
Is doing it myself straightforward enough or do I need a PhD from GM? Anyone have experience with this?
