As I'm reading I see some people swapping sensors such as the MAP for a 5 bar or changing their low pressure fuel pump for a RS3 unit with a different controller. I understand the controllers are PWM devices.

 

Would anyone know if this is done by coding (eg VCDS or OBD11) or programing (eg Cobb etc where they overwrite a table) ?

 

Thanks

The only reasons people would be doing this is - they are fitting a bigger turbo and running more boost so need the extra bar of pressure. And if they are running that much more power then they will need more fuel, hence the RS3 pump.

 

Its not a case of just fitting parts and youre done, especially not the map sensor, this would require a remap at minimum.
