RaceChrono OBD PID questions

[javierhe]

Hi all,

I'm trying to display more information in RaceChrono. One thing I'd like to see is the current gear (with manual transmission). Is that possible?

I tried the following PID: 0x2211B3 but I only get "NO DATA"
Searching around looks like in Torque, you need to pass "TCM" as OBD header, but in RaceChrono, header values are only decimal/hexadecimal.

I found this on the racechrono forum, but TCM value is missing:
PCM - Powertrain Control Module - 0x7E0
ABS - Anti Lock Brake System - 0x760
IPC - Insturment Panel Cluster - 0x720
PSCM - Power Steering Control Module - 0x730
RCM - Restraints Control Module - 0x737

Does anybody knows the hex value for the TCM header?Is it 0x7F0, or 0x7E1? Maybe I need a response header as well...

Thanks!

I was looking for the same thing a while ago but struck out. I did find something that plugged into the OBDII but it used speed and rpm to determine what gear you are in so it only worked when the clutch was disengaged. I was looking for something that told me what gear I put it in before I released the clutch as an extra measure of safety to prevent mis-shifts. Unfortunately what I was looking for doesn't exist.

I got it working with raw CAN bus connection (using OBDLink MX+) and this reference for PIDs: https://github.com/v-ivanyshyn/parse_can_logs/blob/master/Ford CAN IDs Summary.md

Here are the screenshots of RaceChrono equations:

But the bandwidth isn't good enough, many frames are dropped on bluetooth route. The next step is to pack different PIDs into one frame and send it to RaceChrono through bluetooth. The bandwidth gets reduced ~5 times. It requires your own hardware though. I did it in this way: https://github.com/v-ivanyshyn/GPS-racing-tracker

i've never had an issue with my bandwidth with racechrono. i've since swapped to racecapture but i posted my racechrono profile over here with most of the pids i currently use already preset
