Ok,The two methods of the trans mod is: Sonnex has a 15 ohm resistor inline with the pressure sensor. This makes sense to me as whatever value the switch is sensing will have a fixed amount added to it. But the Transgo has a 220k resistor parallel to the pressure switch. Now if I remember things right, don't you add the two parallel resistor together and divide by two giving the value? So I guess if we knew the range of the pressure switch and did the math we could compare the two methods side by side. How about a hybrid with one resistor inline and a parallel pot to fine tune? Will have to determine the range of the pressure switch. Any inputs welcomed.
