Starting Problem Ducati V2

My Ducati Panigale 2 cylinder has MAP-based synchronization.
The engine's starting performance, especially when warm, is very poor.
In the diagnostics, I always get error messages such as:
Bad Sensor
Missed Trigger
Small Pulse
Rejected Pulse
Perhaps someone from Motec could take a look at my settings.
Thank you in advance.

Hi,

Try moving the Engine Sync Pin Threshold down to 3.1V, you have a double dip on the signal, with the secondary at times meeting the threshold value, thus giving the errors.

Hello Stephen,
Thank you very much for your help. I have now seen in the M1Firmware help section that the value for a magnetic sensor should be set to zero. Is that correct?
I currently have the original Ducati sensor installed. Or would it generally lead to a better result if I converted to a
Hall sensor?
Best regards, Ralf

Hi Ralf,

The Engine Speed Pin Threshold should be left at 0.0V as the signal is crossing at 0.0V.

As long as the sensor is configured correctly, I see not reason to change from the existing tested Mag sensor, to an aftermarket Hall sensor.

The Sync is set as a Mag sensor in this specific usage, but as you are not reading a Mag sensor, but a MAP sensor for the signal, then the Threshold is configured based on how the signal moves on the induction pulse. With a MAP based sync setup, there are no fixed settings that we can supply, as each installation is different. Even the same sensor on the same engine will often require different settings.

Another thing to be aware of using a MAP sensor for sync -- you will likely need different settings at high altitude. I setup a V-twin KTM SuperDuke on an M130. All was good until they went to a hill climb where the base was 8000 ft (2400 m) elevation. I had to help them tune the dip value remotely.

Also you always need to start cranking with the throttle as closed as possible to generate the best MAP-derived pulse.
