12. INSTALLATION OF THE FAST MAPPING SWITCH
The FAST kit also includes the FAST mapping switch, which utilizes a three-position switch complete with wiring, which
makes it is possible to select one of the three different maps stored in the control unit’s memory. There are three positions,
the top position of the switch for full power (map 1), the middle/central position of the switch is the original map (map
2) and the final lower position of the switch is the wet map (map 3).
The control unit has three map formats stored in its memory:
• Map 1, full power, developed to optimise maximum power at all speeds;
• Map 2, original, which is the same as the original control unit’s map format of the bike;
• Map 3, wet, adjusts any functional irregularities, making for a smoother response, ideal for wet conditions.
The rpm limit(redline) has been increased on all three map formats by 200-300 rpm.
The control unit can be used in conjunction with a PC software interface so that in the event of special preparations, it is
possible to download various types of map formats, which can also be customized as required.
The software can be used to alter the engine parameters and is therefore potentially dangerous, unless used by skilled
personnel capable of assessing the most appropriate kind of use according to the type of bike and the engine charac-
teristics involved.
