I found that formula on a page with a lot of calculated PIDs. It’s MAF g/s * 3600 (3600 changes g/s to grams an hour) \ AFR * 820 ( 820 being density of fuel I think). And FC12 is AFR commanded but with more decimal places.
Oh wow, that link has great explanations, thankyou for that

Thanks heaps guys. Glad you agree those PIDs are definitely at least for MAF. If FC43 is for the MAP sensor FC2C must also be cause the graphs look almost identical, but they are inverted compared to the MAF on a graph. What does the E represent in that equation Antus? And would you think it’s possi...

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 i...

Hey, I have a VY Calais and have installed a set of VZ Calais seats, VY’s didn’t come with memory seats but VY2 and VZ did. Since I completely rebuilt the seats I figured I may as well source all the parts to convert my passenger seat to a memory seat also, was simple to do but sourcing the parts to...
