2022 Panigale V4 Rev Limit…?

Ducati Forum

Help Support Ducati Forum:

I remember @DeussenEngines saying there were restrictions on the SF which weren't present on the Panigale. Which makes sense given it's gearing change and different use case scenario. I'm curious to hear his input as I'm sure he's worked with both.
 
Maybe but the restrictions are gone on my bike. These bikes have multiple levels of restrictions. They mostly exist in the ETV maps. Apparently, there's a max torque nanny but since I'm at 5000 ft (and up) I can't invoke it. I am curious how the ecu calculates this.
 
Nope apparently it's a calculation since there's no way to measure directly on the bike? You could do it directly but it would take some engineering (like measuring twist of the output shaft). Has to be a combination of air pressure, air temperature, rpm, fueling, ignition? At some point I'll start messing with it to figure it out. But as of yet it has not had any impact on my tuning.

There’s an air pressure sensor on the 2ndary air system that could calculate altitude

Thats the part number for a support bracket to hold the secondary air valve and manifold pressure sensors of the rear cylinder bank. :rolleyes:

Ambient pressure (absolut pressure used for altitude correction) is measured at stopped engine with the manifold pressure sensors and updated while running at load by a calibrated difference between manifold pressure and ambient pressure.

It was #12 in that schematic whatever that is haha 🤷‍♂️
 
OK. But the torque nanny must be the sum of various sensor inputs. If I get on the gas in death valley (below sea level) I suspect i can provoke it. If this were to be accurate won't it need the tire/gear calibration. I have a question for Mr. Duessen, if the horns (velocity stacks) are motorized is there a map (I can't see one) for horn length relative to rpm? I liked the microtech ecu because you could correct the sensor curves (slopes). And I see your software also has this capability.
 
Bummer on the stacks. I'm a little bit slow, are they simply measuring the pressure differential to activate the torque nanny? Man did I overthink that. They do consider torque multipication too right? As in gear selection?

Torque safety is a beast. It basically doubles many ECU maps in reduced size and complexity. If you are at sea level or at altitude the sensitivity is still the same. It does not care about the vehicle but only about the torque generated by the engine and basically checks if the driver request is within an accepted tolerance of the calculated torque delivered.

Yes of course there are maps in the ECU to control the variable intake. In the Streetfighter they are unused as it has fixed stacks. But in the Panigale they are used. With your Woolich software you see probably less than a percent of the calibration parameters available in the ECU. My most extensive mappack features currently about 450 maps and parameters. And that's still less than 10% of all the maps and parameters existing in the memory.

Ok. But if the sensitivity is the same it's still based on available intake pressure which decreases with altitude? Is this wrong? Air pressure at 5000 ft is reduced by .97 to the 5th. 14%. My assumption is I can't provoke it. I ride between 5 and 13k feet. Again as you say it's calculated torque.

You can provoke it at any altitude depending on how aggressive you make changes in certain maps in the ECU.

Then it's not a torque map. At 10,000 ft the torque would be around 75%. Make no sense you could trigger this at any altitude. Sea level tq would be over 120 ft/lbs to provoke it at 10k ft.

It is indeed not a simple torque map. Like I wrote before it is a whole structure.
