MS and WB gauge different readings
 

So, this morning I went for a drive and my Innovate gauge shows about 11:1 while MS is showing 12.5:1... I can't see why MS would be reading that much leaner than the gauge. The settings in MS are set to LC-1 0-5 10-20 AFR and the Exhaust settings under basic settings are set to wide band.

Where else should I look to reconcile the difference?

is your lc-1 outputting 10-20:1 ? that's not the default.
