Proform 850 dialing it in closer

I have had this unit for 3 or for years now. Give-up on it........fight with it.....give up........now trying to figure it out again.
When @Mattax showed the bad soldier job on his socket and i found similar problem i was a little excited(fighting it for so long didn't get my hopes up to much.)but was still disappointing.
Mine is the LM2
My last attempt on this thing is going to be a ign switched relay, right off the battery.......If that don't fix it........its not a power problem.......at least not on my side of things.
neg side of THE LM2 is attached directly to the battery. Yes cigarette lighter is grounded at the battery!

I took some recording from the race yesterday, but haven't down loaded them yet.
all i know is that every time i look down at the meter after a run......Frozen!!! My tsp was always reading when i looked at the screen.
I will get into that story later, if i find any valuable data..........................


You’re going to have enough time and effort in that deal (and maybe money because it isn’t cheap to go to the track and then have something fail) that you can buy a real data logger and log anything you want.

You may not think that fuel pressure, MAP and any other things are not important, but you can learn from them.
