Bluefire parameter question

[Rnagel951]

There are a few parameters that do not show up on my BlueFire screen. I started with the Screen from Rusty Nuts. Everything seems to work on the original screen except "Fuel level". I tried adding it again, still shows empty. I tried enabling J1708 data also, but no luck.


The other parameters I would love to have would be DPF pressure and Fuel pressure. I get "NA" as a value when I select those parameters. I contacted BlueFire, the response, suggested I read the manual.......

I know the ECU has an active DPF pressure measurement data, I have a replacement sensor. I suspect that the ECU also has active fuel pressure measurement data. It would be nice to know those values.

Did you go into the settings and setup all you fuel tank information like how many and size? You also need to have the “calculate” boxes checked in the fuel/def settings. On my 2018.5, the ECU does not output DPF pressure or Fuel Pressure, with the engine running, go through the Drive and Repair pages, anything grayed out or has N/A the ECU does not output for the Bluefire to read.

Thanks, I will check this section of the setup. I am new to this app, so I figured I was missing something.
As for the other parameters. I was looking through the Advanced section of the manual. It looks like if I can figure out what PGN or PID the data I want is located in, I would be able to get it on the display. I do have a copy of all of the parameters and addresses of the J1939 specification. I might be able to figure it out....

Thanks again for the help!!

Thanks Rusty Nuts! I had a fuel tank setting wrong.

Now off to figure out if I can get DPF back pressure and fuel pressure on the display. The setup looks sort of straight forward.....

Yeah it can get tricky finding that missing setting sometimes I was told by Mark at Bluefire that if the items in the Drive and Repair pages are grayed out, it can’t be read with the Bluefire, that was a while back but things may have changed, post back of you figure something out.
