The diesel engine died and I swapped it out for a 1.8 8v from an 87 MK2 but didn't have most of the fuel injection parts so I ran it on a carb for a while. After researching Speeduino I'm mostly sure this is a better route than trying to round up all the very old Bosch pieces.
The current goal is to start with just do fuel off MAP/TPS and work towards distributorless ignition with a trigger wheel.
Hopefully this is practical enough. I'm only collecting parts for now. I picked a fuel rail with regulator ( VW digifant stuff ) and fuel pump. I also have a trigger wheel and EDIS coil I got off a car I was scrapping. I see there are lost of options for assembled boards but one thing I need info about is harnesses to the ECU. I know I'd be splicing into my ends for sensors and such, but I'd like to not have to make the board end.
Either way, I'll be asking around and looking for existing info here during this journey.
