    Digital coolant Temp guage using factory temp sender

    Can anyone tell me if its possible to use an after market coolant temp guage using the factory temp sender on the 4tech engine?

    If so, anyone point me towards one?

    Everything I've looked at seems to require its own temp sender

    The only thing the sensor does is vary the resistance with temperature change. Each guage interprets the resistance and displays a corresponding value. It's possible you could use the factory sensor - but the ECU needs the info also for proper operation. Just add a new sensor - plenty of places for one.

    thanks tchies, I'm aware how the sensor works, my questions is more with regards to, do different sensors provide different readings and there for the guage needs to be calibrated to the sensor its using...

    My setup I need to measure the temp in the head at the same point as the factory sensor which is why Im asking.

    The Autometer website indicates they need their own sensor... but is this just them marketing so they get a sale of a sensor when they sell a guage as well... or do they actually need a sensor that is calibrated to the guagte
