2021+ programmer

tigerboy81983 · May 9, 2023

I've been looking for a programmer for my '22 Tahoe in order to turn off the AFM and start/stop function, but it seems like no one makes one. Superchips and Range both make products for the Silverado/Sierra but not the SUVs. What gives?

Global-B Architecture.

It's on the 21+ T1 SUVs and 22.5 refresh pickups and newer. It's a locked down system and not at all easy to crack. AFM delete might come eventually, but I wouldn't hold your breath.

As far as start/stop function there are a handful of places making harnesses that you install in-line with the existing button. It stores the setting of the button when you turn off the ignition and sends that value back to the BCM the next time you start it. I installed one on my '22 Yukon XL Duramax the day I brought it home and it's worked flawlessly.

Does that also mean there's no options for adjusting tire size either?
