The main challenge will be the return springs on the ITB setup, you may have to remove these or reduce their rates as there will be a limit to the DBW actuators strength.

FWIW, I have manaully actuated the butterfly in my DBW throttle body, and it seemed MUCH harder to do than any cable actuated butterfly. That spring and motor seems pretty stout.
and as such would be pretty hard for a dbw motor to work against.
Add up the effort needed for 4 or 6 throttles and compare to what's needed for one throttle
That and most makers of ITB's don't want to deal with DBW because of the basic liabilities involved.

Fenix Oh I know it can be done by converting to cable but like I said wanna know why it couldn't be done by DBW electronic opening and closing like the single throttle body that comes standard on my car
