You're Ms won't controle the vvt properly either. You can use the Ms to switch it on/off on a vtec fashion but it doesn't work great on the st. You could delete the vvt and you could buy a stand alone controller.
You could run it on the oem st ecu. All depends on expectations, ability and budget.
okay so I will need an st170 manifold for throttle bodies.
Does it take much to delete the vvt and use my Ms ecu? I have been told by several people that if im running it on fireblade 42mm throttle bodies in my light car the vvt may not be worth messing about with, tempted to just use the engine without?
