Update -
I use one of the fuel usage options on the center display and this gives you a current mpg, best and average. Before installing Carbyte the current mpg would go to 99 when taking foot off the pedal and always coasting downhill with no throttle. After installing Carbyte it would only hit 45-55 mpg coasting. I didn’t notice any significant changes in fuel consumption with ASS and DFM disabled, but that display never went to 99 coasting after installation of Carbyte. Think this is proof of running full time V8.
Yesterday I was driving over the bridge that is part of my normal drive and when I looked down at instrumentation I saw 99 going down the bridge and off throttle. When I got a chance to pull over and check, the Carbyte was gone. I didn’t pull it out, nobody has been in the vehicle but me and Tahoe spends the night in my garage. Nothing else is missing and no evidence of vehicle being broken into. I haven’t had it in for service since I got Carbyte.
Really weird, I guess I must have hit it with my foot getting out but I think I would have felt that. No signs of it on my garage floor, or around my driveway. The device plugged in nice and snug and it definitely isn’t any fault of fitting. If I can’t find it I will probably get a new one as it worked well and disabled the annoying ASS.
