I glanced over the Wiki entry for Digifant.
The author is not very Vanagon focused ...but more Golf/jetta focused.
he talks of the ECU havinga knock sensor as an input ..
our vanagons of course do not.
I could-should dig out a jetta ecu I have and see if it says 'Digifant
II' on it ..
wouldn't surprise me if it does.

In our vanagons though ..it's plane ole Digifant to me.   Bentley too I
think.
the author also talks about the 'Air Control Valve (IACV)'  as something
the ECM conotols.
As if that valve was controlled by the  ECU in Vanagon in our Digifant
systems.
It's not mainly of course..
but rather by the Control Unit behind the right tail light.
it's just not a vanagon-digifant focused article really.
Better than nothing if one has no idea what digifant is ..
but not very useful to use Vanagonauts.
Not very well  written in my opinion, kinda jumps around.
Also strikes me that the author is more into the digital functioning of
the ECU guts more,  than into the real world of dirty engines that don't
run right due to Digifant System parts, signals, or wires that are not
behaving. Like a bit theoretical and not 'in the trenches of the real
automotive world.'
Whatever ...it's better than nothing let's say.  Just doesn't fit
vanagon digifant that well.
