I'm discussing open source tuning with a guy that says I will run into problems with tuning my
ecu saying 'has its own set of map definitions which I will have to translate to stock refs which can take a while and leaves room for error with base maps.'
I don't understand what he is saying really but it is my understanding the RS 40 and regular wrx would be exactly the same?
Can anyone here explain to me what he is/could be on about?
