I have a similar problem, except that mine will on occasion drop back to
something that looks correct after running for a while.  Whacking the dash will

I also discovered the pulse.  :)

My flexprint seems to maybe be defective right there at the tach, but I haven't
messed with it for fear of wrecking other things.
