PCM Logger 21 - Testing

Post by bubba2533 »

I've been using PCM Logger for testing of my new custom OS and I've found some issues.

I'm going to try and document the issues that I've had so that they can possibly be reproduced and resolved.

Logging Halted Issue:
I've been able to reproduce this error multiple times.
  1. Open PCM Logger
  2. Connect Device to PC (VX Nano in my case)
  3. Select Device
  4. Select Parameters Tab
  5. Error "Logging Halted" in Display Area
  6. Selecting a parameter to log does nothing
Debug Log:

Code: Select all

PID Boolean Profile Issue:
I've been able to reproduce this error multiple times.
  1. Connect Device to PC, Open PCM Logger, Select Device
  2. Select Profiles Tab and Open Basics Profile
  3. Open Parameters Tab and add Boolean Parameters "Cold Startup" & "Loop Status" (Both are from PID 1105)
  4. Open Profiles Tab and Save As new profile
  5. Close PCM Logger and re-open
  6. Select Parameters Tab and now 2 "Cold Startup" Parameters are listed

Thanks for reporting these. I'll look into it.
Please don't PM me with technical questions - start a thread instead, and send me a link to it. That way I can answer in public, and help other people who have the same question. Thanks!

I'm starting to address the computer side of my swap and I get the 'Logging Halted' error quite frequently. OBDX VT.

Can you post in the debug log so we can see a bit more? Hopefully it gives a bit more details why its saying logging halted.

Will do, sorry for not thinking about that first. I'll go out today and get some data.

...and of course I'm unable to replicate the error. I'll post up a debug log when I'm able to get one.

Has anyone found the pid for fuel flow? I’m almost certain it’s FC1C but but I can’t figure out an equation. I know it exists because my Snap-on tool has it and the snap-on doc says the PCM gets the data from the PIM. Looking at a graph of a log of both FCIC and fuel flow from OBDFusion are almost identical too. But they also are extremely close to all the MAF PIDs. Unless I’m completely wrong and this PID is just another MAF PID. And the other possible PID’s that also look similar are FC2C and FC43 but these 2 PIDs are actually the opposite when comparing the data on a graph. Thanks. And also thank you for all the hard work that you guys have done and continue to do, I really appreciate it

fc1c is maf related
fc43 is map related
fc2c is fuel related, but don`t have exact meaning

It should be on SAE J1979 pid 5E from https://en.wikipedia.org/wiki/OBD-II_PIDs
I've also got GM pid 163A, 2 bytes, with N=(E+512)*65535/1024
The J1959 pid would be the better one to use as any vehicle that supports fuel rate should provide it with the same equasion.
