Hi,
Is it possible to use the SPARCEADC input instead of the CLT input for coolant temp?
Lurking around in tunerstudio and the docs it doesn't seem like that.
Reason is that MS and a temp gauge will share the sensor, when using the CLT input R10 will most likely add current to the sensor and cause inaccurate readings.
SPAREADC doesn't have a VREF pull up, so that would work. (There might be a slight current added by R16 but it's probably insignificant)
This is for Microsqurt.

If you can find out what the bias resistor in the gauge is, you can use the 'Calibrate Thermistor' function in TS and changing the 'bias resistor' value according to a quick parallel resistor calculation (gauge Rb || uS R10).

I would need a very good reason to not install a second temp sensor for the MS.
