VW Digifant ECU

[Peter Orban]

Merry Christmas and a Happy New Year to everyone!

Has anyone dug into the Digifant FI, and its potential for modification,
of VWs, 88-92 Golfs and Jettas? Currently there are no aftermarket chips
available for this ECU.
The architecture is a dual processor one: An intel 8039 for the fuel
control, that chip has its code in a 2764 EPROM, and has a TI ADC 0809
attached to it. The other processor is a Motorola 6805 variant for the
ignition control. The processor itself is marked SC 80984, and is EPROM
programmable. Has anyone heard about this particular chip?
Any information and discussion on the above would be much appreciated!

Thanks, Peter
