Little update. I won't be able to do anything on this topic for a while. Just picked up a 1980 Fiat Spider 124/2000. Fuel injected, cable driven speedo, and more wiring issues than I would like to admit. I'll start on this again once I can get the turn signals and brake lights working.

I don't have an accurate mpg right now because a day or two ago the fuel line that attaches to the fuel pump popped off. That was a fun and smelly drive home and to the parts store for a new filter and some line. I'll try and top it up and get a baseline mpg reading when I can, then I'll move on to the whole "I don't have a VSS I don't think" bit.
