Good 'ol vagcom. Did a lot of tweaks to my old Audi A3: No more seatbelt chime when in park, enabled running lights, tweaked steering weight and added remote window up/down.
I'd *really* like to shut up the non-stop engine on chimes on my 2017 volt. Even the quietest volume level is super loud.
Anyways, rant aside: There's an android app called MyGreenVolt which connects to a cheap bluetooth ODBII adapter. Gives you a ton of info and is all-around stat nerd candy. No way to change settings though.
The only thing I know of, was from my old chevy days (8 year ago), before I got my VW, before we got our new volt.
TunerCat ( http://www.tunercat.com/ ) was used by those interested in messing around with their engines performance. No idea if it would understand the 2016+ volts, or if it has insight into anything other than engine/trans stuff.
Other than that, just never seen something like Ross Tech in the GM world. I've been out of the loop for almost a decade playing around in the VW programing space, but quick searches aren't showing much has changed. At least nothing has general consumer friendly as Ross Tech.
Personally, I was hoping for something approximating vagdashcom.de's dongle and software. I reprogrammed so many instrument clusters I lost count. Would be great to be able to at least tweak the CUE software, or customize the cluster.
