Haha nothing up my sleeve here. Genuinely curious about data logging systems for the car. I'm installing aftermarket gauges for oil pressure and also adding warning light switches for things like oil pressure and fuel pressure. One thing I am struggling with though is I would like to be able to monitor the ECU's misfire / knock counter. I have not found a good way to do that. I've ordered a few DC volt monitors with high / low alarms set in them and I think that I can use them to start triggering at specific thresholds to let me know when knock is occurring but I have absolutely no idea whether this approach will work.

I've used an m327 device in conjunction with several apps before and they're pretty decent for data logging. As small block said though, the PID reference values are very specific and Porsche and sensor feeds beyond the most basic ones are not readily available for use.

Does anyone have a good reference for PID numbers for different sensor feeds? I've checked out Neff Moto but haven't had any luck yet. I've got to read through the Land Rover manuals because they have a much more detailed explanation of how their system works utilizing the same ME 7.2 system. Otherwise I'm just kind of making this stuff up as I go (as usual)!
