Entering the search term I provided into Google, the second search result I
get is for Digifant as used in the '86-'91 Vanagon:

http://www.westfaliat3.info/Vanagon_Protraining_Digifant_I_86-91.pdf

Page 6 of pdf as shown online mentions the Vanagon 2.1 engine. I had found
the same set of images via another link but this appears to be the same
manual.

Since I'm still a newb to Digifant, I can't attest to the veracity of this
pdf, but this looks like the correct Digifant pro training manual.
