Default MSPNPPro-MM0105: Coolant Temperature Output


I'm looking to adjust the coolant temperature output values so I can run an aftermarket gauge. I'm using the stock 2001 temp sensor and harness. Coolant temp gauge is wired through the X-16 connector.

Tuner studio shows 170*F, Autometer gauge shows 255*F

Any thoughts?

Your autometer gauge needs its own sending unit. Disconnect it from the ECU.

What Ben said.

Your autometer gauge, like nearly all temperature gauges, isn't looking for a voltage input, it's looking for a variable resistance to ground. Your ECU cannot emulate this. (I'm not aware of any that can.)

Long story short: install a temperature sensor appropriate to the gauge.

You MIGHT be able to spoof it with a generic PWM output. But this is going to take some trial and error.

Use the ECU to drive a stepper motor on a potentiometer!

Looks like adding the autometer sensor is the way to go. Thanks for the input guys :-)
