There is oddly little ECU/BSI/onboard computer hacking (beyond flashing a tune, mostly to change engine specific settings). Or maybe there is, but I never managed to find an active community that goes beyond ecu tunes. I guess it's due to how fragmented the hardware is (even if most auto manufacturers usually source the components and systems from the same vendors).
