This explains why I never found anything when sniffing the traffic. It becomes a needle in a haystack if it only refreshes every 3 mins. Thanks for the info. I’m going to resurrect my RPi and take another stab at this.

Curious if there's anything that operates like the E46 'temp gauge' does!
(The temp gauge has a very large range of values where it will display straight up without moving. The thermostat housing has a heating element in it to artificially open the thermostat at lower temperatures to provide greater cooling to the car in certain conditions. Basically they run the engine hotter/colder depending on whether you're driving for fuel economy or performance and don't want customers constantly going to the dealership because their coolant temp is constantly changing.) |

I tried sending 0x2A2190 to the CAN ID 0x750 and didn't get any responses. I heard TPMS data isn't available immediately after starting the engine, so I drove around a medium-sized block before doing trying those requests, and kept the engine running throughout. I tried both with RaceChrono, and using my own DIY device plugged into the CAN bus. As a sanity check, I tried sending OBD protocol requests with standard PIDs using my DIY device and I did get the correct responses. One possible theory is that I should just drive more after starting the engine before trying to send those requests. Or maybe I the requests I was sending were just a little off the correct ones... ![]() |

Have you guys ever compared TPMS readings with readings from a high-quality traditional gauge? I have a few times and there is often error of two or more PSI. In my experience TPMS is not exactly that useful at the race track.
Hopefully TPMS sensors have become more accurate since I checked them. Or maybe they can be recalibrated somehow. I don't know much about them. But I think it's important to recognize there can be significant inaccuracies in them.

Edit: I see your from denver colorado! see there's your problem lol. your around 5.2k feet above sea level lol your getting around 12psi ambient. while were close to sea level we see 14.6psi so that's where your discrepancy comes from.
