This is with respect to non synchromesh, sequential transmission. Ducati along with several after market systems, implement clutchless downshifts by automatically applying a slight throttle to unload the gear.
I understand how clutchless upshifts work.
For clutchless downshifts - while I understand the concept behind blipping the throttle while coasting, engine braking and hard braking helps unload the gear, I do not understand how how this could be achieved perfectly.
I want to understand how this process is automated - timing, logical order of events etc. (Main question)
I believe a sensor on the gear shifter (strain guage) gives input to the controller of the riders intention to downshift.
The controller slighty blips the throttle to unload the gear and engage the lower gear. The blip also helps in revving the newly engaged gear and possibly helps reduce RPM mismatch resulting in smoother engine braking.
Am i correct in the above two statements? How is the amount of blip calculated (is it rev dependent or is it not so sensitive)? Is there any tendency to upset the bike (by working in opposition to braking)?
