I think you guys are confusing switching maps with reflashing your ECU. Check out GOAPR.com or RevoTechnic.com. They both allow you to swap between tuned map and stock map with a switch. Its like like telling Windows & to emulate XP. But you are still running aftermarket flash and if it were sent to Germany they could definitely tell there is a different file on your chip.

Softronic.us actually sell the flash, flashing software and cable that then you use to flash your own car. Flash is locked to your VIN, so you can not give it to your buddy. If you choose, before visiting a dealer, you can flash 100% stock software back to the chip. Basically using previous analogy, you blow away Win7 and install XP. When you get the car back, you once again can re-flash it yourself. Nifty. Porsche only ATM.

I like more clarification for OE, as to what exactly they do.
