BMW 1 series as Beam.NG controller

Basically we made our PC the engine control unit for the vehicle, normally the engine ECU tells the car instruments the speed,rpm and everything else. we connected those data wires (CAN-bus have a read and look it up how it works) to BEAM.NG with some virtual and phsycial interfaces in between them so we can translate the games RPM value to something the car will understand
