Hacking your (electric) car: the importance of Open Data
summary
Argues that car telematics belong to the owner and shows how to extract and decode them: scan ECUs with an OBD2 USB or Bluetooth adapter, dump all PIDs, discard static entries and compare scans (pedal pressed vs released) to reverse‑map signals. Reports finding 35 ECUs, roughly 1,000 PIDs and about 27,000 raw entries, from which 330 variables were identified; demonstrates enabling features (unlock charging power, enable Android Auto, move infotainment gauges), uses Python scripts, DDT4All and CANZE, and pushes a shared open database and free scanner tools.
