If so, seems like a tuning pot in the circuit and you could tune the response to the gauge to whatever you want, long as the response curve of the sensor is reasonably close.

The problem is there is no response. You can't tune it if it's not there.

First post says:
"The gauge spikes during crank"

That sounds like the dash is wired for warning lights instead of gauges.

Cars with warning lights ground out the temp sender wire while cranking for bulb test.

That solid ground can jar the needle loose (cause it to slip) on a gauge.

This old thread has some good info about sending unit ohm values and resetting needles on a gauge.
