I was thinking along similar lines as you, but I wanted to try and control the duty cycle of a solenoid with the solenoid controller output of a UTEC, and set it up to only operate under 100% throttle to avoid having to "tune" it for any other condition.
It was just idle thought, though.
My friend is an electrical engineer/"black box" extraordinaire. He's gotten bored and made everything from auto-learning EBC's to contraptions that operate the clutch for you as you bang gears (worked well with Ikeya Formula sequential shifter). I'm trying to learn more about how the AVCS works so he can make a controller for it.
