ELM327 to RS232 in Linux
I have been having car problems recently. However, these inspired me to dig a little into the car ECU. ECUs (engine control units) are able to give out a myriad of information, like systems’ fault codes, real-time RPM, air-flow, fuel consumption, voltage, exhaust state, and lots more. Most modern cars tap into this information and display it on the dashboard via on-board computers.
I finally received the long-awaited OBD II (OBD 2) (on-board diagnostics) interpreter based on the ELM327 chip yesterday and all I can say is that it’s been a long night.
