I have been reverse engineering automotive ECUs for a while now - https://github.com/bri3d/VW_Flash https://github.com/bri3d/VW_Flash . It's a nice change from my day job in enterprise engineering management, and I've met some fun people and taught several folks a lot of new concepts, which is always extremely rewarding.
My latest project has been reverse engineering the data-flash encryption in Simos18 ECUs. After some work, it oddly appears the encryption algorithm used is Mifare Hitag2. I'm hoping to be able to re-encrypt NVRAM channels soon, although the overall data flash "filesystem" / channel-system layout needs some more work before I am ready to release my findings.
- ehnto 5y agoThat is wicked. Would you ever be interested in developing an open source ECU platform? I feel like there is a hole in the market for affordable and hackable ECUs. You could monetize it by selling the hardware boards I guess. There are some projects out there already but none of them seemed usable for a full size track car at the time, and the issue was still a lack of suitable hardware to run it on. Idealy you could just buy a board with a generic wiring harness for ~$300, and have an open extensible platform for engine management in the software. Kind of like the ecosystem for flight controllers for drones.
- bri3d 5y agoHave you looked at RusEFI? It's definitely usable for a full sized track car at this point, and their hardware looks pretty smart and reasonable to me. I haven't actually used or contributed to it yet, but I plan to buy a unit and see where I get as I am working to convert my old 280GE from K-Jetronic to EFI.
- ehnto 5y agoThat looks a lot like what I was envisioning now, they have come a long way since I last looked!
