Hi everyone, I own a Nissan X-Trail T31 2008 2.0 DCI. I managed to set up my Realdash using an obdlink mx+ in CAN mode with an.xml file. I’m only missing 3 parameters (RPM, AI, boost in bar).
Unit: 0.25 RPM / LSB (service manual page MWI-27 says 8191.875 is displayed in case of malfunction, implying that the whole 16-bit value of A.8-B.1 – hypothetically 0xffff in that case – is simply divided by 8 to get the RPMs)

I am extremely grateful for your valuable help.
Yes, this is a question to perform the calculation of the formula.
Here is the test you asked me to perform.
Bytes do not seem to match the description on the github page you linked.
Lets try one more thing:
With engine running, go to CAN Monitor
Let engine idle
Press ‘Record’ button on bottom of the CAN monitor screen.
Raise RPM to 1000 for a couple of seconds and then let it fall back to idle.
Do the above couple of times and then press record button again to stop recording.
Exit the CAN Monitor to the dashboard and go to ‘Settings->Application->Datalogging’
Use the ‘Export Files’ button to export the latest rdcan_DATE.csv file
Send that file to me for analysis.
We have a CAN simulator that is able to play back the datalog recorded from the CAN Monitor. That we we have a better chance to find the missing RPM for you.
OK thanks I ran a test today with version 2.4.6. The RPM works perfectly with the same.xml file, but the engine temperature does not work. With older versions of Realdash 1.9.x, the RPM does not work, but the engine temperature is operational. I don’t understand why
The offset=“8” is not correct, that would indicate 9th byte of the CAN frame and frame has only 8 bytes. I don’t believe those issues are because of the update.
If your highlighted byte is the right one, that is on offset=“0”
In general, everything is going well now. All that remains is to find:
Throttle Position
Intake Air Temperature
Boost (Bar/Psi)
Average Fuel Consumption
Fuel Level
I will try to identify with can monitor I would be delighted if you could help me make the task easier
