That's a good point; something I could learn from on my WBX

Don: if it helps, and I know this sounds obvious, but I think of the
specified gap as the switching point. (I think Bentley refers to it as
such) So, say, at .007 mm this is when the ECU is told what to do. Or
in other words, foot *slightly* on gas, is where the switch point
happens AFAIK.

Hopefully your version of Digifant has a switch that's easier to set
than the WBX 2.1 That thing is kind of a joke (taking into account
worn parts)
