That is thanks to Switchleg's work building the patch 'SwitchPatch', which enables a much better traction control system, launch control, map switching, and some other stuff I don't fully understand. But for what you're after, yes on-the-fly map switching is easily available, meaning you can drive down the road on a more economical tune and then see something fun, hop over to your aggressive map, and then go dominate the skreetz. All without ever having to stop driving.
SimosTools allows you to flash from an Android device, SwitchPatch is a patch for the stock BIN file applied using BINToolz.
