v3.6 + LSU4.9 + Wheel speed

[Jim_W]

When upgrading to the LSU4.9 sensor when the original board was built for LSU4.2 one of the wideband wires conflicts with the wheel speed input. Can anyone point to how to connect a wheel speed sensor after upgrading to LSU4.9?

4.2 and 4.9 pins on the ECU does not change at all. The one change is a 27k pull-up is needed on the nernst to 5V. No pinout changes at all. Not sure where you're getting that information.

There's some information here: https://www.vems.hu/wiki/index.php?page=GenBoard%2FManual%2FWBSensor
And a PDF of the sensor pinout and even lists the ec18 connector locations, which match LSU4.2: https://vems.hu/download/sensors/LSU4.9/LSU4.9_pinout.pdf

Thanks for correcting me on that. I see I made an error on my wiring diagram and put pump- on pin 8 instead of pin 7 where it belongs.
