Live Map Switching is an end user feature by M-Engineering. Map Switching allows for the storage of up to 8 separate calibrations on the ecu at one time which can then be chosen on the fly, and with the engine running, by using the cruise control stalk in a matter of moments. No need to remove the ECU to reflash for calibrations optimized for higher octane. No longer will you need to drive around on race gas all the time if you have a calibration designed solely for 100+ Octane. A few simple flicks of the cruise control stalk can have you switching from your 93 octane file you drove to the track on, to your MS109/C16/VP Import file designed for the track!
