monitoring of brake pressure

edited March 2019 in RaceChrono for iOS

Modern cars, for example my BMW F22, can give brake pressure by OBD-II like other sensors (and I can see it in other iOS soft like BimmerLink). It's very important information for improve driving, even more than throttle position. As I understood, now RaceChrono doesn't read this sensor.

May be RaceChrono team can add this sensor?

    There will be custom OBD-II PIDs feature in the next version. You may be able to get brake pressure through that. You'll need to know the PID and formula for this data on your car. Usually best place to search for this stuff is in brand specific forums.
  • Hi when will this custom PID version be available (roughly). Thanks.
  • Soon in beta testing.
  • Coming back to the brakes in F22/F87 BMWs: I am presented with a brake pressure value in some pre-configured apps, like the BMW-specific OBD Maven. Yet I struggle to find the correct PID and parameters on the Internet, so I could record it using RaceChrono.

    Can someone help out with brake pedal position (BPP), brake on/off (BOO) or brake pressure?
