CANbus data

[ccnncc99]

I spent a bit of time playing with RaceChrono and an OBDLink getting some CANbus data logged on my 2019 GT A10. I'm sharing my profile in case it's useful to anyone else - https://drive.google.com/file/d/1o0nFcKDj93ihn9y4ZPx9YZ8IT72R5jUq/view

Here's a list of parameters I was able to pull:

OBD2:
Gear
Trans temp
Tire pressure

CAN:
Brake position
Coolant temp
Engine RPM
Gear
Trans temp
Speed
Steering angle
Throttle position
Individual wheel speed

This is good info. Thanks.

Do you know for sure whether the Coolant Temp really is coolant temp or if it might be Cylinder Head Temp instead. Just asking because so many of the gauges reflect values derived from CHT. And, I’ve been told CHT is heavily weighted in determining when and how much to pull timing.

The coolant temp looks to be the ECU's calculated value. I haven't found the PIDs for CHT yet but that's on my todo list.

Please let me know if you do get CHT. It’s somewhat frustrating that so many traditional engine health indicators are calculated. But at least once we get CHT we’ll have some raw data to draw on.
