LSU4.9 five vs six wire sensor

EMU PRO
1

I want to clarify before I order a five wire sensor that the EMU PRO is going to be okay with using that on the dedicated sensor input.

I presume that it will be okay. And, of course, I would love to install a six wire but… anyway. Later. I will definitely do it later.

Hi,
There are no variants of LSU 4.9 with a different number of wires.
Not sure where you got that information, but it’s incorrect.

The original Bosch LSU 4.9 has five wires between the sensor and the connector and six wires between the connector and the ECU/controller.

The extra wire after the connector is present because it’s a special connector with a built-in calibration resistor trimmed for that sensor during production.

Okay thanks.

Here is the datasheet from Bosch:
