Ah I think I see what happened; I forgot to add one of the configuration commands required to enable flow control mode 1. I've updated the command sequences below:

Tire speeds?

Code: Select all

ATCEA29
ATSH6F1
ATCRA629
ATFCSH6F1
ATFCSD29300000
ATFCSM1
22DBE4

This might get us tire speed, which we might eventually be able to use to pull tire pressure.

Time in gears

Code: Select all

ATCEA18
ATSH6F1
ATCRA618
ATFCSH6F1
ATFCSD18300000
ATFCSM1
22DA37

Please try running the above again; we should get valid responses this time

Tire speeds looks like it might be working! Adding some potential parameters in https://github.com/OBDb/BMW-X3/pull/11. Please refresh your parameters and confirm SHA: b527851. To test the tire speed parameters you'll need to have the tire speeds parameters page open while your car is moving — please don't use the app while driving though! You can open the tire speed screen while parked and then move without having to use Sidecar; it will logs the values at a quarter second interval as long as the screen is open.

I've also added some pids from the i3 for ODO and speed in case maybe they work on the X3 too.

Sent, please check if tire speed is logged

Confirmed that the tire speeds appear to be working ok! I'm noticing that X3_VSS is also working and seems to be consistently reporting as slightly higher than the standard VSS parameter, but it's also more accurate. You'll be able to pick between the two parameters in terms of which one you'd like to use as your vehicle's Connectable for speed.

Looks like the odometer values are reading as well! Based on the values, does an odometer reading of ₂₃,484 km sound right @chihengyang?

I don't see many other obvious parameters we can try to onboard, so going to promote the 2023 to onboarded!

Yes, odo value is correct and same as instrument panel.
