It didn't work on my 2016 Silverado, the check engine light came on and the truck won't start with the device connected.

2012 gmc sierra. So far it's what it should be. My display shows v8 only and I do notice less stumbling. It's more a seat of the pant thing as still to early to tell mileage changes. Only a handful of uses so far. I noticed the lights do go out fully when I turn off ignition. Not sure if there's battery drain yet. I'd like to leave plugged in if there's no drain. If anyone knows more about this unit please add a comment. Hope it's going to last and price doesn't reflect quality.
