MM3 with Lite Tuner

[Minnesota_farmer]

Was just cleaning off my MM3 (with truck keyed off) and it turned on (from touching the screen i suppose). Now it doesn't follow when the truck is keyed on or keyed off. I have to turn on and off manually. Also no longer have my real time tunes in the top corner. If I get on the throttle it feel like it's in my 90 hp default tune.... but I need to tow a 15,000 lbs trailer tomorrow and I need to get it back into the 30hp mode. HALP ME haha.

Ok. I shut the truck off. Unplugged OBD. Key'd truck to run. Plugged OBD back in. And everything seem less fine. If I should do something different, let me know.

You got it brother. Sometimes you have to reset the tuner by doing what you did. Sometimes in other cases the ecm has to be reset by unhooking both batteries for a few minutes and reconnecting. Such occurrences are usually a result of drop in voltage below threshold. Most often a weak battery or a poor OBD connection is the blame.
