A90/A91 Toyota Supra PT-CAN BUS Install

Post by TYRFRYR »

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.

Thanks for the update! Not all vehicles are obvious for their CAN bus location, so this will be helpful.

So after some deep dives, I've mapped out all of the Supra supported OBDII PIDs as well as several CAN BUS IDs.

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

The CAN Presets and the required Script Preset are on Podium as Shared Presets.
