scott said:No dont think you cant alter them yourself.
The product key is just so you can use the RSTuner Pro on other RS cars.
You have to take your car for a good run, collect the data, save it then send it to henk.
He will create a custom map based on the info you sent him.
Once you recieve it back you just upload it to your ECU.

So let me get this straight:
You plug the RSTuner into your cars ECU,
Take the car for a few test spins taking it up to the limit,
Send the data to Hank at Fastchips and he will send you the data back but modified to suite,
Then you upload it to the RSTuner, plug it back into your car and upload the files to the ECU !
