What voltage is the nxd5000 progressive controller looking for from the throttle signal, My 2002 dodge diesel only outputs 3.5 vdc and I know gasser's are 4.5vdc.

Could this be the problem with the progressive controller not learning the throttle?

I have tried everything twice, this progressive controller is from Nitrous Express is a real pain,

Unless someone can tell me something I will go to a fullthrottle switch instead

It sounded great and the support from those people is like asking a question into a black hole.Basically no service at all.
