I've done the "TBI" version of fuel injection on my old supercharged 22R. It's an improvement over the carb. With an 02 sensor, you'll pick up some mileage over the carb and inclines won't be an issue. For the naturally aspirated setup, you don't really need spark control - just run your stock distributor setup to keep it simple. The fuel injection is simply add-on.

You could integrate with TWM hardware also. I had considered a big TWM setup as an upgrade from the TBI at one time.
