:tractor: Collect of CAN IDs and its payloads for various car brands/models in one place. Might be useful for Cyber Security Researchers, Reverse Engineers, and Automotive Electronics Enthusiasts.
A community-maintained index of CAN bus message databases for ~40 car brands and several motorcycle manufacturers. It's a link aggregator, not a structured database — every entry points to a spreadsheet, GitHub repo, or blog post maintained elsewhere. Useful as a starting point for automotive reverse engineers who need to find what's already been documented for a specific vehicle.
Coverage is genuinely broad — BMW, VAG, GM, Tesla, Volvo, Nissan Leaf, and a handful of EV-specific entries are all represented with multiple sources per brand. The EV section is particularly useful given how hard battery management CAN data is to find. Actively maintained (last push July 2026 on a repo that's years old). The motorcycle section is a nice differentiator — most automotive CAN resources ignore two-wheelers entirely.
It's a list of links, not a database — formats are all over the place (Google Sheets, .dbc files, .h headers, blog posts, Russian-language forums). Several sections like Acura, Lotus, SAAB, and DS are completely empty. Link rot is a real problem here; some entries already point to web.archive.org, and the Google Sheets links will break without warning. There's no way to query it programmatically — if you want to know 'what CAN IDs control the HVAC on a 2018 Tiguan', you're manually clicking through links hoping someone documented it.
