Acole1017 Posted April 22, 2022 Report Share Posted April 22, 2022 I have a 350z pNp ecu and im not getting any wheel speeds. No MPH on the computer while plugged in. I have RPM and everything else but not wheel speed. The cars speedometer still works and so does traction control and ABS and the car doesn’t throw any codes. Is there some setting i need to change to make this work? Quote Link to comment Share on other sites More sharing options...

Vaughan Posted April 27, 2022 Report Share Posted April 27, 2022 wheel speed should be coming in over CAN but a quick look at your log show's nothing on CAN Freq 1 input, do the engine fans work properly? as in you can change the temperature values to force them on and off?

Acole1017 Posted April 27, 2022 Author Report Share Posted April 27, 2022 yes the fans work as they should just hooked up to the car and changed fan 1 and 2 temps to 60 degrees fahrenheit and they both turned on Quote Link to comment Share on other sites More sharing options...
Vaughan Posted April 27, 2022 Report Share Posted April 27, 2022 If the fans are working then the CAN bus is working, exactly what vehicle is it and do you have any way to sniff the CAN bus? Quote Link to comment Share on other sites More sharing options...

This is on a 2007 G35 sport coupe with the revup engine. I have a snap on scanner at work that should be able to read CAN Quote Link to comment Share on other sites More sharing options...
Vaughan Posted April 28, 2022 Report Share Posted April 28, 2022 Chuck the sniffer on and see if you have any data on Ids 644 or 645, if those Ids don't exist on your CAN bus then see if you can find what Ids have values that change with wheel speed.
