   @penelope @bob The SAE J1979 that defined standard explicitly states that the only valid thing you can put through the OBD2 system are parameter identification numbers (PIDs) to request diagnostic information.  
   
   It wouldn't terribly surprise me to learn of non-compliant vehicles though.

      @maiyannah @bob I mean you can very easily upload an entire new fuel map through the OBD2 port you can use it to control rpm and all sorts of things with a simple OBD2 interface or dealer scantool
