A discussion about the new electronics

I'd like to have a discussion about all of the new electronic wizardry on the Panigale. There's a lot of new features but some of it may not be doing what you think it's doing.

First, the ride by wire throttle is controlled by the ECU and it is intigral to most of the new systems - lets take the riding modes:

Some people assume that riding modes are actually ECU maps that adjust ignition timing and air/fuel ratios for different results or conditions, uh... no:

Riding modes are simple variations in throttle opening as controlled by the ECU:

Race mode is as close to 1 to 1 (hand to throttle body) linear as Ducati can make it but there may be some variations to control engine characteristics as assumed demand by the throttle position and rate of opening. I generally have a problem with that assumption part of the equation.

Sport mode attempts to give a smoother throttle response by creating an exponential throttle body reaction to your actual position and rate of opening - slower (than your hand) at the beginning and faster toward full open.

And rain mode gives both an exponential curve and limits full open position so that at no time can you go to wide open throttle.

Now lets take a look at the new slipper system or EBC: Engine Brake Control is not a new type of slipper clutch but is more electronic algorithms to work the electronic throttle. EBC monitors throttle position, gear selected and crankshaft de-acceleration rate and administers throttle openings to balance the torque forces acting on the tire. EBC has a three level operating system and is integrated into the three Riding Modes. In other words it's a form of RPM matching that can adjust the amount of deceleration by adding throttle wile slowing.

I'm hoping that this system is variable and one can tune it to the desired effect. This is one of the new innovations along with the quick shifter that sounds really good to me and may work really well.
But it is frighteningly odd to have the ECU add throttle when you have the position at fully closed and you're trying to decelerate.

Comments, corrections, and additions are welcome.

I Ride: 1199 ABS
Interesting and well done on the explanation flynbulldog

All sounds the same mode control that the Diavel and Multistrada have. They both work well as do the DTC and ABS functions.

As for the EBC this is a whole new concept for Ducati and we`ll have to see how well it works.
I also think that the slipper/servo clutch as used on the Diavel/MTS is used as well.
So there will be 2 systems controlling way that the bike is controled during braking/deceleration.

As for the quickshifter, if it is the same as the 1198SP std equipment it is a very basic unit. Hopefully there will be a strain guage fully adjustable unit available soon.

Thanks Dave, I haven't read a mention of the Slipper clutch for the 1199. I wonder if EBC is an addition to the slipper system or a replacement?

I guess the slipper function is here in the Panigale along with the EBC, I found this:

New for a top-of-the-range Ducati Superbike is a “wet”, oil-bath clutch. Based very closely on the design of the Multistrada and Diavel components, the clutch assembly features a “slipper” function and a progressive self-servo mechanism that compresses the friction plates when under drive from the engine. While enhancing frictional efficiency, this also results in a rider-friendly light clutch lever “feel” at the handlebar. Conversely, when the drive force is reversed (over-run), the mechanism reduces pressure on the friction plates, enabling a true racing “slipper” action, reducing the destabilizing effect of the rear-end under aggressive down-shifting and provide a much smoother feeling when closing the throttle or down-shifting under normal riding conditions.

I thought the level of EBC was determined from the rate of change of acceleration / deceleration of the crank and was more to prevent highsides etc rather than acting as a slipper clutch.

what do you think a slipper clutch is for?

The slipper clutch is for down changes on corner entry etc & doesn't contribute anything when it comes to preventing high sides. The EBC is more for traction control

No I think you have it backwards. The EBC Electronic braking control is to prevent the wheel from locking on downshift - just like a slipper clutch.
and, one can highside from either deceleration or acceleration.

I had better re read the manual then

Do you have access to a manual? I'd love to see it.
