on the scanmaster at idle its .82 and at wot its 4.49. is this right? and if not could it have an effect on wide open throttle shifting?

 

I don't think it should matter. When you start the car, whatever value (eg - 0.82v) is taken as 0% and then should linearly increase to the max of between 4.30-4.60v. Make sure it increases linearly when you slowly press on the pedal.
