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.

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
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.
