who owns/uses a LM_2?

Yeah i get that there is no accuracy at idle.
But when i "fat foot it", going down the road, gauge reading freeze, quits reading. have to shut it off and sometime when i restart it, it starts working again.
Full throttle is what i want to read and it craps out everytime!
I haven't when and checked the possible power and grounds, so i need to do that first.
It just weird that is does that. and it is instant. Pedal to floor, and it stop right then and there. maybe it the launch that is pulling on a wire or something. Got to get out there and make sure everything is right.

But, this is race track work day. got to add some lights to the christmas tree so spectator can see the action. run wire so we can install our, end of track scoreboard. And work on some glitches in our new timing set up.

Race is next week and i'm not ready but neither is the track.
