I Hacked My Car Guides: Creating Custom Firmware
On a related note, factory-installed Toyota display systems can sometimes be locked and require an "ERC" code to unlock. The display in my recently imported car was in Japanese and seemed to be stuck, as none of the buttons or rear camera worked. I learned from Google Translate that it was in some kind of anti-theft lock mode, and after going down the rabbit hole I found out that I could access a secret menu by holding radio power and turning the headlights on and off three times, which revealed a screen displaying the display's serial number and asking for an "ERC" code.
It turns out some fine Internet people have written C# (https://github.com/alexeyfadeev/erc-calculator) and Python (https://github.com/Berks/python_erc) packages to generate these codes. Was really cool to figure this out without having to pay some shady site in Bitcoins! The display is still in Japanese, but at least I can use Bluetooth and the rear camera! Hope that helps someone.

How to get fast data to a track app on an E46 M3
As for the packet encoding, there's some open source info here: https://github.com/commaai/opendbc Another place to look is the RaceCapture Pro user community, as they map out CAN broadcasts for various cars and share it.

rusEFI Proteus: two CAN buses and Lua scripting. Also an ECU :)
Luckily for me there is a lot of data to build on top - there is https://mdac.com.au/2021/04/11/dsg-control-with-rabbit-ecu/ article, there is https://github.com/RabbitECUProject/RabbitECUTeensyMCUXpresso/blob/main/source/Client/DIAG.c source code of how RabbitECU solved the same problem, and there is a https://github.com/commaai/opendbc/blob/master/vw_golf_mk4.dbc

My first CAN BUS Project.
What vehicle is that? Did you decode CAN packets or found information on the internet? Do you have any new CAN DBC knowledge to contribute say into https://github.com/commaai/opendbc which seems to be the largest catalog of DBC files?
What are some alternatives?
