The best person to speak to is Alan Gibbs you runs the www.kalmaker.com.au
site and is the sole distributor. Do you know how the cam timing is manipulated? I assume it would be either a stepper motor or PWM, I would be more inclined to think the 2nd.
You might be able to use one of the 2bar outputs to do this function but it would be a lot of work to set it up. Wastegate control IMO is just as good when controlled manually provided the turbo is sized right.
