I have a Innovate MTX-L wide band sensor. My set up in megasquirt is set to Innovate LC1 Default.
The problem is that i have a difference between the reading of my gauge and the one in tuner studio. My gauge is 1 point richer than the one in tuner studio. What is the problem and witch one is right???

Thanks!!!!

John

The MTX-L's own reading is the one to trust; get the MS to match up with it. Where is the MS grounded, and where is the MTX-L grounded?

Matt,
I suppose they have to be ground together and they are not.

Matt,

You're always right
Ground at the same place, same reading...
