1. Hold down "ECON", and press the "up-vent" button (next to recirculation). Both temperature displays will read 00 or 00'0, and you can release the buttons once they do.
2. Twist the LEFT temperature knob until the display above reads 19’0.
3. Twist the FAN knob until the left temperature display reads 19’1 (like 19.1).
4. The right temperature display is now a digital speedometer! HOW COOL IS THAT!!!
--- For tach (in x100), twist the FAN knob until the left temperature display reads 19’3 (like 19.3)
--- To reset and go back to normal operation, hit the ECON button once.
