Yea what do you mean electronic wastegate? I am assuming you are getting a new holset (IIRC the VE series) with the smart actuator (not wastegate). Do you have a link to the turbo you bought?
Also it is likely a lot more difficult than you are thinking. Moving bits around is easy. Reverse engineering the protocol, and/or taking over the mechanics of the stock actuator is not so easy.
Again, assuming you are getting a new holset (IIRC the VE series) but it really depends on what route you want to take... But here would be your options:
1) Create a simple controller, research/reverse the CAN interface. Interface your controller to the CAN. Command over motor/actuator position over CAN.2) Do some machining to get your own stepper/servo onto the stock gearing system and then have a simple controller to control your servo/stepper (which would likely need to be remotely mounted due to heat)3) Rip apart the stock PCB attach directly to the existing motor + encoder (I assume). Then you will need a complex BLDC servo controller but can use the stock motor.4) Something completely custom in the mechanics (and electronics) department that controls the actuation. Don't use any of the stock actuator.
