With that being said.... you talked about restrictions I assume it's not a typical Jap top speed restrictor due to seeing other BMW's already surpassing the 186mark. What other restrictions are you referencing?
Lastly by adding timming to various sections and it sounds like up to +3 degree's and still sustaining 93 octane usage...I'd be curious to see the gains. Is the power restrictions in timming more so then RPM limit?
There are multiple levels of restrictions we've found:
-Torque limiters intervening ignition with increased horsepower
-Ignition timing limiters by gear (upwards of 5deg in lower gears!)
-Ignition timing limiters by mode (anything lower then race)
-Ignition timing intervention at shift or traction
-Throttle limiters not letting the bike go full throttle on 100% WOT.
-Kat overtemp fuel intervention - based off EGTs the bike will add fuel to perserve the factory converter in race scenarios - which will limit a kat-less bike.
Nothing done with a piggyback or PCV will do anything to the above. This is important when mapping the bike.
