Being able to run ITB's on OEM management would be super tasty modification.
FWIW I've gone out of my way to retain Digi 3.2 on my car as it'll be vastly better than K-jet. K-jet was an ingenious solution to a problem at that time but imo it has been surpassed and it's fairly well documented that it'll lean out at the top end with the ABF and potentially kill then engine.
I do hate though that the MAP sensor is integral to to the ECU, that is a pita if it fails.
