I wonder if the Pikes Peak prepped Street Fighter (this new one) will have something like 2 (or perhaps 3 .. maybe 4) stage ECU setups that the rider will be able to switch to as the altitude increases up the run? It seems like an obvious set up for the Pikes Peak run, doesn't it?

Does the "stock" bike have an ECU system capable of doing real time set up changes on the fly?

Sounds like a good idea. I can tell you that the Tuono 1100 ECU does not do that. It calibrates when the ignition is switched on and then runs the appropriate map from that point on. If you check the forums, a lot of people have complained of starting their bike at the top of a mountain run only to have it start running poorly or stall as the altitude gets lower.

If you've ever looked at a calibration map there's a section (a row of cells) that calculates altitude and you can dial in the amount of fuel adjustment at each interval - every FI bike has this, it is automatic and works without intervention. However most maps only adjust up to about 10,000 feet, PP is 14000 at the top and once the actual altitude goes past the last step/cell in the row it reverts back to sea level, that's bad at 11000 feet! However, if you have the ability to alter the map you can change the value of each cell so that instead of starting off at sea level it will start at say 4000 feet and each cell after that will increase accordingly. That way the ECU will adjust up to 14000 feet.

One thing that most people dont understand is the concept of map settings. For our production bikes different "maps" are nothing more than an adjustment of the throttle butterfly position in relation to the twist grip. Map settings do not give different fuel tables. I'm only talking about the fueling portion of the setting not things like traction control, wheelie control, brakes etc. On factory race bikes it's a different story - different maps may or may not also change fuel tables.

The streetfighter is unique in this aspect - it was designed on the cusp of the ride by wire revolution and thus it has a throttle cable and does not have throttle maps, but it does have the very earliest form of traction control. This traction control on the SF works by cutting fuel and ignition - not by limiting butterfly position.

The Multistrada and all of the later bikes work in a very different way from the SF - The SF and the 07/08 1098R were pioneers in production bike traction control

Good information!

So, do the Pikes Peak rules of homologation prohibit the use of aftermarket systems in the class/division this new Ducati is entered in?

Anyone put down a deposit on a 2020 SFv4 yet? I'm thinking about it.

I'm not keen enough on the bike without first knowing how it rides and handles. It has to be worlds better than my current streetfighter and give me something more than my Tuono before I'll jump. I'm in wait and see mode on this one. I might even wait a year and pick up a used one if I still like it by then. I want to know specs, especially rake, trail and wheelbase. I'm not interested in another "overly stablized" version of the SBK
