Alfred and the List,

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,

Mark Ingalls

Hi Mark,

I read sometime ago that you built yourself a Digitool for your 85 Digijet ECU. I am trying to build one too for my 85 Vanagon as well. I have looked at Darrel's site for the instructions, however his plans are for the Digifant ECUs. If you have built the digitool for the Digijet, could you please e-mail how you have done it. I have the Bentley manual, Darrel's plans for the Digifant Digitool, but need some guidance as to which wire connects where for the Digijet. Your help will be appreciated

Thanks

Alfred 85 Westy
