in case of a VR sensor connected to the ECU as single ended, signals should be connected to the ignition input

Ignition In (9), and the signal’s output to Bipolar Ignition Out (4).

In the case of the balanced signal (differential), VR sensor should be connected to the DET3 device as single ended,

and connected to the car’s ECU as balanced, using both bipolar outputs.

Polarity of the sensor is crucial in case of the balanced signal. Reversed connecting will cause an inability to start

the engine or errors in controlling the ignition.

For the VR sensors, in the menu Setup/Ignition Configuration choose the Ignition Input Type: VR Sensor

Adaptive Threshold. (Applies to the single ended sensors as well as balanced).

Caution!

Signals from the VR sensors should be lead by shielded wires, especially when they are

longer than 15 cm.
