Bren,
Sounds promising and it will help even the field once the ZX10 guys flash their ecu and add pipes/filters etc. The BMW unless this is done will likely not surpass some of these ZX10's that have a good tune on them. Just the flash alone on them add's 20+hp add pipe, etc and they are the same or maybe slightly higher then the BMW's power output.

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.

Awesome well like eveyrone else....really excited to see the results. I thought I had seen where the throttle won't open 100% in this or another forum that I had read. The retarding in lower gears is pretty typically to help keep folks off their lids with this much power. I had the Busa done and wow what a difference the extra advance made down low in 1-2-3 Have you determined how many degrees is pulled however in 4th....we may not gain any HP with this normalized from 4th and up gears. Unless we "add" or advance it...sadly we may all be stuck at the peak power unless we go race fuel with Oxygenated fuel with the timing to support that.

Ready to see what you come up with once done...

Just to add, theres a lot of talk on here about the different modes, I'd like the ability to leave rain and sport alone completely ( they serve a purpose) and make the changes solely to race and slick.

Although I don't ride in Rain .....it would be nice to keep "sport" stock if possible if I let someone see how the bike handles etc.

There is lots of room in advance on pump 93, We will make 100oct files as well.

We have found the respective degrees retarded per gear as well.

Awesome good to hear. I wondered if they were conservative on the timing since pump gas does vary greatly from time to time and as the season changes and we go into winter blends vs summer etc. With the built in Knock sensors it will also help prevent detno as long as your map does not force the advance even thought the system does see some pinging taking place. Should be a great gig for us when you get it figured out.
