I was trying to work with guys here at work to come up with a computer controlled barrel valve so as to not go 100% efi, but bigger projects first.
Maybe even a Microsquirt could handle the single output for a servo controlled barrel valve? Then just a baro, TPS, etc would be needed and hidden? hmmmm
Seems to me the drive motor for an electronic LS throttle body could be adapted fairly easily for a barrel valve. And the control strategy has already been figured out by lots of aftermarket ecu manufacturers.
