Cool.

Thanks Dennis. That's also what I was curious of.  I had the ECU open
recently, but don't really know what the various components do. But
Googling now......

This Megasquirt ECU image indicates where the FI driver(s) are. They
look like FET 's to me.

I imagine the controller on the Vanagon Digifant ECU uses a FET to
control FI pulse?

Not that it matters. I doubt my ECU is the issue.

Neil.
