panigale v2 does not detect gear when changing the transmission kit

Full4crack said:

I have changed the transmission kit of the Ducati panigale v2 2020 from 15/43 to 14/44 and when I am driving the motorcycle suddenly the gear I am in disappears and the neutral N appears activated on the neutral led and it flashes traction control. After a random time passes, the gear I'm wearing reappears on the screen. In addition, the downhill quickshift often fails.

Has anyone come across this? How did you fix it?

thank you so much

greetings

All Euro 5 Ducati OEM calibrations have a diagnostic active to detect a gearing change. You can fix it only by ECU reflash.

I took it to Ducati and after reconfiguring the gears again, the problem continues to appear, as well as the gear change sensor failure. Ducati has requested the sensor for warranty to change it for me.

When you say ECU Flash I assume it is what was explained above.

Thank You

Ducati cannot fix your issue. In Europe a motorcycle manufacturer has to ensure that the bike meets the emissions standards. When the final drive ratio is changed the emissions can be higher than allowed and therefore a diagnostic is monitoring the gear ratio. I can disable this diagnostic by changing the calibration inside the ECU.

Shouldn't Ducati know this and not try to replace parts that won't fix the issue?

Or this dealership is shady and is defrauding Ducati through unnecessary warranty work.

That escalated quickly. I'm reminded of Hanlon's razor...never attribute to malice that which is adequately explained by stupidity. I don't mean that as a slam on the mechanic either. I don't presume that he's factory trained on the Panigale V4 or any other Ducati merely because he or she works at a Ducati dealership.

What about changing the quickshifter? I've been told locally that switching to a better QS will fix the missing shifts when running shorter gearing. How true is this?

Now with the 14/44 the downhill Quickshift is failing. Sometimes it works, sometimes it doesn't, it has all the logic in the world if the bike detects that something doesn't fit. The display shows an error and that error is the gear sensor.
I will try to make a video in progress so you can see the problem but it is very similar to what you see now. a black stripe in the place of the marches and the N of neutral blinking like the traction control of the m

Would the gear learning procedure help?

Correctly executing the Tyre calibration function that you can select in the dash board will fix the downshift blip issue but it will not remove the diagnostics issue.
