If you bought your RSTuner from fastchip then you get the stage 1 map free. Just email Henk with a screenshot from the rstuner program main screen as that has the infomation on what version your ECU is etc and he will send you the correct files
Depending on your software version and firmware, that could either go well or horribly wrong. Not all the 1*2's share the same ECU details. That's why buying new and following Henks instructions on getting the activation map is the best thing to do.
