The Attached DME Pin Out document was used to locate the BMW PT-CAN Pair (Yellow/White - Yellow/Black). Having identified the PT-CAN bus, the wires were traced back into the cabin. They are readily accessible after removing the passenger footwell outer kick panel. The Picture below shows the PT-CAN bus connected to CAN 2 of a RaceCapture Track MK2 using a standard Cat5e Ethernet Cable.

EDIT——-
As for CAN Mapping, the BMW F87 presets seemed to work well, but after digging and logging more of the CAN packets, I discovered that they quite work out. I’m working on updating the CAN Mappings and should have a preset to publish here in a couple of days.

Re: A90/A91 Toyota Supra PT-CAN BUS Install
So after some deep dives, I've mapped out all of the Supra supported OBDII PIDs as well as several CAN BUS IDs.
Fixed with firmware v.2.19.0
BMW CAN Bus Data
The CAN Presets and the required Script Preset are on Podium as Shared Presets.

OBDII and CAN Bus Mappings:There are a couple of CAN BUS IDs that require LUA Script to process the 12 Bit unscaled integer data.

Re: A90/A91 Toyota Supra PT-CAN BUS Install
Great News!! We've decoded the OBD-II Service 0x22 message structure to access BMW Enhanced PIDs!! This greatly extends the data we can log from the DME. So far, we have the DME PIDs for the B48, B58 and S55. We're actively working on other ECUs and will be updating the ECU PID maps as we decode them.
There is a BMW CAN Bus data write up posted here: The SECRET Ingredient!
We're currently testing a Lua script that will allow you to retrieve BMW Enhanced PID data!! Once the script has been tested, we'll post it to the website as well as upload it to RaceCapture as a scripting preset!!
Enjoy!!!

Hello,
Do you have the DBC file for this? Running some standalone stuff. I also emailed you regarding this. Hope to get a response soon. Good info.
Many thanks,
Rich
