hey guys i thought i would post some info to help anyone with hpt pro that has the isspro pressure/temp sensors. the formulas for the additional inputs can be derived from the info on isspros website about volts/temp or volts/pressure. you simply run the green wire to the hpt pro connector with the appropriate ground and for example my 120psi gauges use the formula (input/0.02285714) + (-21.25). Now this formula only works for sensors 175 psi sensor (gauges from 100 to 180 psi except Trans Pressure). i can do the formulas or show how for other sensors when i have a little time this weekend but i thought i would share this now. and the best part is you dont have to disable your gauges just extend the green wire from gauges!!!!!!!!!!!!!!! i use this to look at boost and drive pressure cause having the manual tranny they are always moving!!!!!!!!!
