what do you need to flash wireless? I see roadrunner offers it.

The Roadrunner emulator is a small emulator that fits right inside the PCM and communicates with the OBDII RT Tuner program via a high-speed USB interface or by an optional wireless (blue tooth) interface.
Drag a point on a graph or enter a new value into a table and the new values are immediately sent to the Roadrunner automatically so the PCM begins using the new values instantly.
