It's common for a larger OEM like VW to write large parts of the application software themselves and send it back to the Tier-1 ECU supplier only as object files. (The industry is competitive, worried about IP protection, and anything clever in the powertrain ECU application software could easily provide a competitive advantage). Bosch would have ultimately integrated it and built the final ECU software, but I very much doubt they ever saw any source code from VW. |
