V4 Pp Ecu Update

Got a link (assuming there was more detail)?

 

I just called my dealer and asked - he went through improves throttle response on key off, improved reaction on display of RPM and gear selector. Nothing really exciting.

 

That’s not my dealer. That came from the V4 FB page.

 

What does throttle response on key off mean?

 

Wonder if that includes settling my rpm needle down. It does wobble a bit

 

From a forum:
Update to the CR240 software change:
According to my local dealer (Ducati Omaha), it contains:
Following continuous quality checks on the vehicle concerned, we would like to inform you that a new engine control calibration update has been released with purposes related to ensuring better product reliability and improving the user experience, specifically:
Changes some diagnostic strategies
Improves throttle closing strategy after Key OFF
Improves the refresh rate of the engaged gear indication displayed on the dashboard and the rev limiter

 

Ahhh that clears it up

 

Mines been updated today, approx 15min.
No noticeable difference, still as smooth as ever…….. what a bike

 

So if this is the same tune it’s 10% fuel saving

 

That has the cylinder shut off for longer though.

 

On all v4 type bikes we can delete the cylinder deactivation. In 2018 the first bikes didn't have it. A few months after release they were forced to be cleaner and a ecu update was forced into the bikes ecu on service . How much heat build up it reduces is not really talked about but it's deactivated for around 30 seconds per throttle blip depending on current temp. And of course the next pull away is a little fluffy.

 

We turn cylinder deactivation off if the customer wishes.

 

Its not that, the Rally has different cams to allow for extended deactivation, we PP owners have to stick with the 'only when stationary' deactivation

 

PP's don't do stationary, so we're missing nothing!

 

Does it really? Have different cams that is. Isn’t the deactivation purely an electronic intervention? I thought the software in the ecu cut the spark and fuel to the rear bank of cylinders. Originally on the V4 they cut in again as soon as the clutch switch was disengaged ie by releasing the clutch lever but on the Rally they cut in as soon as the engine rpm hits 3750 (or maybe it’s 3250). Surely it’s the exact same engine in the V4/V4S/V4PP/V4 Rally?

 

i raised a service request into Italy asking them if my PP could have extended deactivation enabled, and they called me to explain the PP cant be retro fitted due to the different Cam setup, dont shoot the messenger ......

 

I didn’t mean it to come across as shooting the messenger . However, your response made me check the parts diagrams and sure enough whilst the parts diagrams for the V4S and V4PP are identical (for the cylinder head timing section) there are 2 part numbers listed for each of the intake & exhaust cams regardless of whether one’s looking at the V4S or the PP eg.,
Rear intake camshaft has nos 14826131A and 14816511A although it doesn’t say which is which.

I live and learn, although now I’m curious as to what the difference in the parts is and if it’s just the cam profile why that interfere with the ability to electronically deactivate the spark and fuelling in the rear cylinder.

 

I'm sure its combination of black box/ECU wizardry involved in the mystic art of cylinder deactivation, I wish it could be retrofitted to the PP just for those extra mpg's, and I remember the days when you could rebuild a bike with a 12mm spanner and a screwdriver

 

I made the assumption the V4 was the same in all muti's. Clearly not. If Ducati can increase the rear cylinder cut off for the Panigale you would have thought it possible for the PP.
