The gen2 bin file I have has the following
Top speed limiter removed
More timing at lower rpms.
Secondary throttle plates set to open at their most efficient rate, using 100% of already available fuel, every cell, every gear.
Fuel soft-cut limiter removed, redline up by 600rpm.
Fuel hard-cut remains and is the rev limiter(cuts fuel to all cylinders).
Fans on/off 10 degrees sooner.
Ram-air compemsation turned on for Bking, and Bking needs ram-air mod.
Air/fuel ratio is Not changed!
Gen2 Busa and Bking engines are 100% mechanically the same.
Only the ecu bin file, exhaust, and airbox are different.
Flash your Bking to this with airbox and exhaust mods, and it is a completely different bike, much more agressive throttle response.
Well worth doing.
