Here's Darrell Boehler's site on the digitool:

http://www.loam.org/vw/Vanagon/DigiTool/



And, here is what Mark Ingalls did to modify it for use with a 1.9:



  This is how I modified Darrell's Digitool to work with the Digijet FI
on my 85 GL.

For the LED's:

Pin #13 to:--------à l----------ZZZZZ---------Pin 7 for Power Supply LED

Pin 13 to----------à l---------ZZZZZ----------Pin 20 for Fuel Pump LED

Pin 13 to----------à l---------ZZZZZ----------Pin 11 for Fuel Injector LED

Pin 21 to ---------à l----------ZZZZZ---------Pin 7 for Start enrichment LED

Pin 19 to----------à l----------ZZZZZ----------Pin 4 for Throttle
position switch LED

( -----à means the LED, ZZZZZ means the resistor )

I did not hook up a LED for coil pulse. Darrell suggested I use my
tachometer twitch for the coil pulse indication, he had reports of using
a LED on it had caused the Hall unit to sometimes fail.

For the Digital Multi-meter part of the tool I used:

Temp II     02     Temp 1     AFM     Ground

Pin 2     Pin 5     Pin 14     Pin 15     Pin 7

Other Notes:

I soldered a wire to every ECU pin. In retrospect I only need to solder
a wire to all the above Pins.

I had never soldered before. I used a spare chip I had to practice. I
learned to keep the tip tinned for the proper heat transfer.

Please E-mail with any comments or suggestions,
