MSPNPPro-MM0105: Coolant Temperature Output
MSPNPPro-MM0105
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.
