DIGITAL ECU TUNER 3 – User Manual
Optical/ Hall’s sensors
Optical/ Hall’s sensor should be connected to the Ignition In. input. In most cases, this type of sensors have the
“open collector” output, which requires connecting the pullup resistor to +12V (or using device’s pullup pin).
For the Hall’s/optical sensors, in the menu Setup/Ignition Configuration chose the Ignition Input Type: Hall Effect
or optical sensor.
