Can you just buy a FI setup? Or do you have to resurrect your 50 system that has been in a box for forty years and you know something is wrong with it?

Any modern aftermarket ECU will be leaps and bounds better than the laptop sized ecu in our cars. A megasquirt or whatever will run great using the stock D Jet hardware with the addition of modern sensors. I haven't done this yet but I think a simple setup with just throttle position, manifold vacuum, engine temp, and ignition map would make for a D-Jet looking engine that would run really well. Not exactly sure how to get a crank trigger wheel on there though.

That's a great setup! I'm sure there are significant power and economy gains to be had from just being able to tune accurately. Plus less smog. Win win win!

On another note, it's annoying how expensive throttle bodies are for our cars once they wear out so after a bit of poking around I found that the TB from a 04 Chevy Aveo is the same diameter and has a TPS already. Might work with an adaptor plate. It also has an internal idle port and valve.
