Really?
When you power up you PCV initially (with a laptop or computer) the TPS function pops up first, if it doesn't its easy to find in the menue at the top of the screen. You can see what the voltage is on the screen without the sled running if you power up through the 12volt pulg in the wiring harness just above your clutch gaurd above your primary clutch. You can also see what the W.O. voltage is when you put the gas to the bar. You have to enter these values into the PCV so it knows what the min and max values are and adjusts the curve accordingly. If your TPS is out of calibration or you enter some bogus values bad things will happen. You can use the PCV to help you acheive the correct TPS setting but it will not do it for you. The minimum voltage is just as important and the 100% (wide open) voltage.
