Bike Stalled And dropped

I have read this entire thread. After having a the same issue. I almost got struck in an intersection due to my bike stalling while shifting from 2nd to 1st gear. Stalling is the not the right words its more like the bike just quit. Very very dangerous. In 30 years of riding I have never experienced anything like this. Sure I have stalled a bike back when I was just learning how to ride but that was always shifting up to early and bogging down the motor and then it stalled due to my error. NEVER down shifting. This is a VERY serious issue that needs to be addressed. Problem is that is comes out of no where. No warning. Does not matter if the bike is hot or cold. This has been my real only issue with the bike. Other than a failing tail light. Bike has been great!

my bike occasionally stalls or shuts off when downshifting to first at slower speeds.

I originally felt it was the bad fueling on the stock bike but now that is cleaned up and it still will do it .

I had my data logging equipment on it yesterday and nothing looked out of the ordinary when it happened im thinking maybe the autoblipper has something to do with it

That is also my guess.

Yeah It is a real shame how many of us have to modify our so called "premium brand" bikes just to try to keep them from stalling on us... Most of the time it to no avail anyway..

Well like I said before ,, it wont "throw any codes" either so the dealer can do nothing as far as replacing anything under warranty... I think Ducati obviously knows of the situation and cannot or (will not fix it) so they just engineer their ECU's programming NOT to throw a code when it stalls... That was they have plausible denial....

How about a Go Pro on a suction cup mount on the tank that shows (wide angle) clutch and throttle input and the dash to show it just randomly stalling. Pictures are worth a thousand words.

In the three years I owned mine, I would say I experienced maybe 10-12 of these stalling events. Not sure if that is a lot or a little in comparison to some of ya'll's experiences.

10 times or 100 times... it only takes 1 time paired with unfortuntate events, like falling off the bike in a turn and getting hit by oncoming traffic. I'm sure only then will they start investigating the problem.

This is a difficult situation. Mechanically, everyone who owns a 1199/1299 with a Mitsubishi ECU could experience this. It is simplistically the ECU not seeing or seeing something that does not jive with other parameters that it is seeing or is supposed to be seeing at a particular time. The only piece of "bike one" that is not modified is the wiring harness, the ECU and the other pieces of engine management (MAP, TPS etc) This does happen to me. Rarely. The time that it happens during shifting, I chalk up to user error. I say this because I do not run a clutch switch. I understand the being a twin at idle to low rpm, there isn't a lot keeping it going. A slight interrupt in spark will kill the motor and that is what happens when I accidentally load pressure on the QS for too long. I accept that. That's on me. That being said, every once in a while when the bike is just idling, it flat dies. Always fires right back up. Has never happened under RPM load. So I can only surmise that in the idle circuit at the time of the stall that the ECU did not see something that it liked and that isn't going to show up on any fault code. Additionally I am convinced that it does not effect all ECU's as not everyone has this issue. Not sure what else to say. Ducati cant fix it is they cant find it. If is a design flaw in the circuit on some ECU rev someone at Mitsubishi Electronics is going to have to look at that. Like I said it happens super rarely and i think all but once (except for the QS issue) it has happened during warmup. I am building bike II with MM electronics and i do not expect to see any of this nonsense.

**Update I got a call from ducati and they're admitting fault because they found something wrong with the motor.. They're going to fix all the damage to the bike ... Once i get the bike back and the paperwork i'll post what i have in hopes that maybe it can help anyone else having the same issues..

Something wrong with the motor? like it broke a rod?, blew a head gasket? spun a main bearing? That's a heck of an ambiguous answer or does this dealership consider anything that has to do with the operation of the motor, "the motor"?. Interested to hear what they had to say.

It's a bad situation to be in, but at least you have one of the best outcomes

My 1299 has consistently stalled since I took delivery...it is headed back to the dealer for the 3rd time and it will stay there indefinitely. I am at the point where I want out...lets see what happens.

Mine kept doing this today, I wish they would fix this problem

Would be interesting to see if there are ECU part/revision #s between problem and non problematic bikes. Again keeping the bike running is a choreographed orchestrated event between ECU and sensors. There really isn't anything else that will cause this besides some sort of rider intervention or materials failure. The ECU is killing the cycle because it is seeing some sort of signal it does not like. If the ECU "faults" the cycle when the other components are sending the correct data then the ECU or that series of ECUs may have a bad logic section or maybe a bad series of sensors. There just are not that many pieces. You would literally have to take an ECU and all the associated sensors from an infected bike (preferably one that stalls often) and build a calibration cell at Mitsubishi and connect a datalogger. It is obvious by the repair remedies that Ducati has employed thus far that their solution is to replace sensors/triggers so they are guessing. Hopefully it will not take a fatality at an intersection to get someone who can move the needle interested in this.

There are two types of stalling of the bike experienced by riders (me included).

Type A) Engine just immediately stops. Bike is still switched on and can be restarted by pushing the RUN button

Type B) Bike completely shuts off. Sometimes it recovers after approx 1s, sometimes it's required to cycle the ingition key and press the RUN button. This behaviour points more to problems with the E-Lock than the ECU (or a combination of subsystems).

im developing my retail flashes with mine and have flashed my ecu probably 50 times and mine still does it. it is possible im not writing to a part of the ecu effected but I don't think its ecu related.

mine has never done it if I use the autoblipper to down shift to first, it only has done it when I pull in the clutch and downshift.

Well that was kind of my point. That clutch switch sends a signal to the ECU to do several things so regardless of which type of stalling is happening to anyone's
Particular bike, the ECU is involved. I know it's a bit ambiguous kind of like stubbing your toe and saying the pain is a brain problem. The fact of the matter in every case is no matter what, the brain is shutting down the bike because of a situation it interprets. There are bugs and or design anomalies in the engine management system.

Well i was going to post up the results from the fix which i thought fixed the bike.. But i thought about giving it a little bit before i posted anything to make sure it fixed the bike but sure enough, it didn't.. Today it stalled about 5 or 6 times.. The last straw was when i was leaning into a hard right turn in 2nd gear when it shut off..
In the RO they said the "reed valve" was stuck open... they repaired it and didn't fix anything. so i'm calling the shop in the morning to take it back

^^ Im not sure if id be pissed or fearful at this point. Shutting off on a 2nd gear corner is beyond scary. Mine shut off mid turn too but i was doing at most 20 kms turning into my driveway and it still threw me off a little because i had no idea what happened.

so my friends were giving me .... about it saying i was stalling the bike myself coming to stops and it shutting off in 1st gear and watching me almost fall off the bike several times. So i started revving the motor to 6-7k so it wouldn't shut off.. But it still shut off as the clutch was fully released and i couldn't save it this time. i can launch my kawasaki this high with no issues and the ducati almost demands you rev it this high to get it going anyways, only my kawasaki doesn't shut off or stall. Luckily i didn't get hit by a car. The guy behind me was paying attention. I dropped it pretty much at 0 mph. I just got a call from the dealership and they said it's 3k in damage for the 0 mph fall. They told me i have to call ducati of america but of course i got an answering machine. Anyone have a good number to call them and ..... them out? I want to get this resolved but i have a feeling this is going to come out of my wallet to fix. Dealership said there's no codes to be pulled and there should be if the bike just shut off.. I call ........ because i was a certified technician at toyota for many years and if a car shut off for no apparent reason there were no "codes" for me to see. I had to wing it and try to replicate the issue. But with threads like this i can really make a point that it's not just a problem with my bike but with almost everyones bike.

Clutch switch not operating, look underneath the lever and see the micro switch is not operated by the lever pin, as soon as this is set properly the problem goes away....... I checked at my dealers and many of the new bikes are affected.
