Speedo calibration after lift
Hi all, new G owner here, 2020 G550. Having a hard time finding answers on how to change tire size/recalibrate speedo after a lift. I had a jeep before and got a 300 dollar handheld that let me edit the settings. What's the process for a G to go to, say 33s and get the right calibration in there?

This thread from @streborx has been the most informative to date:

TL;DR: There still isn’t a confirmed way to successfully do this that I’ve seen online.

Plenty of Google search results available…
I use this device on my LX. It might be worth reaching out to see if they fit a g.

In the past, I've searched Sprinter forums since I figured upsizing tires is common there and the method is probably same/similar. I would see posts about the tire circumference setting there, too, but only @streborx had done analysis measuring the before/after.
I've also reached out to places like mid-city engineering to see if they would be interested in making a dongle for this. Might be worth asking them, too, to help drum up more support.

sent an email to yellow box for you. The good thing about these devices is that they are adjustable and don’t require coding for each time you change sizes. Everything I saw mentioned on YouTube talked about coding which is not the best way, imo. When I get a chance I can pull out my star device and see if I can find any settings that might be pertinent in the coding, though I’ll admit, I’ve not done much coding myself as I’ve not had issues besides recoding new parts. Benz ninja on this site would have that answer, or perhaps calibenz.
