Hi All,

I was wondering if anyone had calibrated their guages in their HCH1?
My speedometer is the most inaccurate on any car I have owned.
It reads 13 to 15% high while the odometer error is less than 0.1%.
I used two different GPSs as my standard.

My tachometer is even worse. It is 15 to 20% high. In this case
I used the OBDII port as the standard. Both seem very high for
a modern car.

Does someone know if the guages are current meters or steppers?
I don't see a calibration at startup so I am guessing they are analog
meters and a reference voltage is off.

Any opinions appreciated.

Cheap tires that were on the car when I bought it. They should be close to the same diameter since the odometer is less than 0.1% off.
