Using one Coolant Sensor for Gauge and uSquirt

Post by 1979-mini »

Does anyone know how to wire up the same sensor so that it feeds the Temp gauge on the dash and the uSquirt at the same time?

The Temp gauge uses a 10V reference, while the uSquirt only uses 5V.

It's probably not possible if the voltage goes over 5 volts or is on a mechanical regulator. At least, not without designing an op amp circuit specifically for the purpose.
