Quickshifter sensor replacement

The Domino and a few others are Hall-effect sensors, not mechanical micro switches like the oem Ducati. The Aprilia is Hall effect as well. The Domino looks like a viable candidate much better than Ducati oem. I may need to get one!

All a hall effect sensor does is have a magnet pass over a sensor to detect its magnetic field. I don't think this is a superior technology in this application. They are generally more durable as there's no moving parts, but they are prone to heat. There's a lot of products in the market that use different technologies to get to an end. Less important is the specific technology, more important is how the manufacturer implemented it.

Take the Cordona. Strain gauge at first glance is the superior technology, but with no ability to adjust its sensitivity, it falls short. For some people its great, and if you're that person I'll sell you one at a steal. Its sitting in a drawer.

really? did you looked at it? may i get a picture from the inside?
i think about changing the mechanical with hall or reed switches, a picture would help.
not sure yet, i mean myriads of micro switches do a good job in this world.

It may be a Domino source, but it is micro switches, not Hall effect. I’ve had it apart to try and get it working. There is a tiny circuit in it to manage the voltage from the two switches.

The Hall effect sensors seem to be 1.8mm total travel to activate. The Ducati micro switches must travel further. I didn’t measure it, but it sure looks more like 4-5mm.

Update on my failed QS at first ride. I replaced the oem QS sensor with the Cordona and no joy. Hmmm? I finally dug out the still new in box OBDStar iScan and after clearing the QS codes I ran the active QS test found the clutch switch shorted like the lever was in/pulled. If clutch lever is in, it kills the QS function.

Unplugged clutch switch at first connector and QS works! The Cordona is/was terrible in that the voltage wasn’t a sharp change that remained as long as load remained on the shift lever as the Ducati ECU expects. The voltage varies with the amount of pressure on the shifter and starts falling off immediately as the pressure stabilizes, even though you’re still pressing or pulling on the lever. The ECU is/was all confused and cut times were very long and clunky.

I put the original QS back on after setting the tension of the sensor itself and now the QS works perfectly, both up and down. So, I ordered a new clutch switch. They’re different in 2021/2 due to the new style “self-bleeding” pump.

I’m doing all work myself and paying out of pocket rather than take my bike to a dealer goon to .... it up.

The Aprilia sensor looks identical to the Ducati sensor, but I didn’t take it apart. It is likely the same.

There's only so many ways to make a QS that functions on a +5V circuit.

I decided to give the Cordona another go. I installed the Ducati/Rizoma rearsets and switched to GP shift. Just a short ride but it seems to be working great. Of note, you don't need to change the Cordona to GP shift, its all done on the rearsets.

I think the problem I was having with the Cordona is that it changes the output voltage depending on the force and direction its used. On upshift when moving my foot up (regular shift) I was applying too much force and the voltage wasn't consistent with what the ECU was expecting for an upshift. With the Cordona you have to think light but firm and fast.

Cordona has been rock solid for 3 years now. Using the Lightech RS (no funky BS linkage to mess with, GP shift only) and the other mods. Shifts like butter and for me, absolutely predictable.

I had issues with the Córdoba but they were user induced, meaning it seems to be sensitive to force and linger times on the shifts….meaning if you just naturally hit it right and blip it right it works great, but if you are varying how hard you sift or lingering a fraction of a second too long on the shift it can act up, at least for me.

Solution one, spend time learning to shift it right if you instinctive motion is off a bit.

option two: I switched to the H&M blip shifter that lets me program the force required to actuate the shift and adjusted it to me instead of me adjusting to it.

we also originally made a CF bracket and attached it to the engine while keeping it off the engine so it wouldn’t over heat, then later attached it to the air channel that directs air from the fairing cutout to the gear position sensor so it wouldn’t be absorbing engine vibration over time.

If I didn't already have the Cordona, that would be the one to get for sure.

Previously I just had it double sided taped to the air duct, but I added a zip tie to be sure. Copied your sprocket cover too.

Looks really good man
