Temp gauge accuracy

mine reads 250* on the gauge @ 190* engine temp with a 175* thermostat. Stock gauges are about as accurate as waving your hand over it and guessing

That's funny, I've had great luck with my stock temperature gauges. The stock fuel gauges not so much :violent1:. The stock temp gauge in my Duster gives a better representation of the actual temperature than the autometer I added to have a readout in degrees. My autometer gets progressively further off as the temp goes up. By the time the actual temperature hits 200*F the autometer reads 210-212. Meanwhile, the stock temp gauge is pointing just above center of range, which tells me I'm where I need to be, as it should.

The autometer gauge doesn't even follow its own sending unit, the Dakota digital controller than runs my fans is hooked to the same sender, it gives me a nice digital readout with the push of a button that tells me my autometer temp gauge reads high. All confirmed with an infrared thermometer. Kind of annoying, since what the autometer tells me doesn't match what my fans are doing.
