I'll probably regret this, but here goes..........

I work on a daily basis with the microcontroller circuits, designing
mainly, and it just so happens that that is all these ECU's are.
Surely, some vanagon driver in the big USA must be involved with similar
work? If I could get a circuit for this DIGIFANT , DIGIJET it may be that
the types of problems people are experiencing are common and could be fixed
for VERY little cost.

As far as your injectors are concerned, I'd bet there is some kind of
buffer/driver chip that feeds current to these little critters.
I'd also bet that this is what has failed, and it's worth about $10.

When my DIGIFANT fails  I'll certainly be taking a long peek inside!
