If tach readings are erratic, there may be electrical static. Try using more or
less sensor wraps and avoid running the sensor wire along other heavily
charged wires. Adding an inline fuse may help.
If tach readings are way off, check your PPR (pulses per revolution) setting.
Temperature Sensors Help
A temperature sensor tells you how hot your vehicle is getting. Installing one
enables engine temp readouts on the gauge screens and the over-temp
indicator lights.
Radiator Fin Sensor
For water-cooled machines. Fin sensors are a very easy install: press the
sensor into the radiator fins. Use a dab of conducting grease to increase the
sensitivity. Do not force a fin sensor that is too large at risk of damage to
the radiator. Available in 3 sizes.
Cylinder Header Sensor
For air-cooled machines. CHT sensors act as a crush washer between a
spark plug and the engine's cylinder head. Available in 3 sizes.
