Why Don’t Older Cars Work if They Have an OBD2 Port?Updated 3 months ago

There are two reasons why older cars below 2008 are not supported today: 

• More modern cars have greater telemetry available from subsystems, meaning there is more data to collect. The volume of data is a key consideration in the value of the connected data. 
• Every car has data encoded differently. OBD2 ports are not like USB ports where they work the same way on every machine. Since each model of vehicle needs to be decoded separately, complexity expands with every vehicle.
