I wired my 92mm Pro-M Maf the same as before, with the IAT sensor lead to the stock Orange MAF wire and one to ground.

My IAT is reading -40 if it is hooked up or if it is not. This sensor worked before when wired in the same way.

I think a big clue here is that the IAT is reading -40 both if the sensor is hooked up or not. So I've ordered a new sensor, and will re wire it to check for good connections. I'll also use a meter on the sensor and see what I get.

My question is do these things spontaneously die occasionally?

 

OK,

Stand down from red alert, recall all ballistic missiles.

It was just a bad wire connection.

 

which is, by the way, the big risk you are taking tying all these gizmos into your control system without a clear need for them.

 

What about the need for speed?

 

Lol, I felt it water dragon!

 

These "gizmos" are a necessity on builds of this level lol.
