Don, Volks,
Please clarify, Will a Digifant II ECU run the EFI on my 87GL -AND
record Fault Codes-? What if any alteration (you mentioned -very minor-
changes, please expand/define) to the ECU plug/pinouts may be necessary. 
Volks, this could be revolutionary. Be still my heart! Can this be
true?  Please tell me 'tis so, and specifically which Digifant II ECU
(is there only one Digifant II in the series) that will work on a
Vanagon. 
And yes my heart is still set on a Subagon (or Vanaru), but I now have
thoughts that my Japanese marriage aspirations for my Vanagon may not be
as time conscience as before.
