Off the line stall

[Mikel]

I now feel there is definitely a problem ! I have had this problem to many times . The latest was starting to pull out of a gas station when all of the sudden complete shut down ! Needless to say this could have been a very serious situation as on coming traffic expects you to accelerate . Lucky for me the oncoming car was actually watching the road and not talking or texting. It looked like the entire electrical shut down for a split second when I pulled clutch to restart nothing ! I could swear instrument cluster was blank on the first attempt to restart do to panic I can't say for sure second attempt to start fired right up. Today I had the problem two more times and no I did not blip the throttle prior to releasing the clutch. I know there are probably threads on here somewhere but all I would like to know is has this exact problem happened to you ? If the number of occurrences is fairly high I think this might be a recall problem if enough of complain.

if it were an electrical shutdown, i would look to battery cables first, and then possibly the reg/rec or stator.

If it is anything like the ETC engined vehicles that I have driven, then I believe it is related to the ETC. I have had cars that, while slipping the clutch at low rpms and gaining speed, will just shut off. It appears as if there is missing mapping, or that there is a jump in the map that causes a crap value that just causes this. When I say "map", realize I am talking about a group of nearly a dozen maps covering a dozen and a half sensors that come together for only 3 outputs: injection, ignition, and throttle position. It almost always appears at low throttle settings and increasing load (clutch position) and is remedied by using more throttle. I know this won't help with it happening, but if this is the cause the solution seems to be more throttle.

Kickstand switch, tip over sensor?

How old is your bike, and how many miles?
I have never experienced this problem, but have read about others that have. The common denominator for them was they all seemed to be in their break-in period.

Ditto on checking battery cables. Somethings not right to just have the lights go out w/o any warning.

FWIW, my cables were loose on both battery and starter relay.

The following link is to a thread in the BMW Sportstouring Forum on throttle body sync. Even though it is from '09 I have used this method to eliminate the stalling issue on my Tenere. i have just over 49K klms on my Tenere and like most people here, I have experienced the stalling issue at takeoff. I tried the various fixes on here and the issue was improved but not totally eliminated. Being a former BMW owner since '95 I knew this method was used then and deffinately worked. At approx 36k i tried this method and all I can say is that since then I have not had a stall at take off. The first time that I tried the method on the Tenere, I disconnected the battery as in the third post in the link but since then I have used the method 2 or 3 times without disconnecting the battery. The reason I have used it is not because of the stall but because it is so easy to do. The first 3 post are the posts most relevant. Remember guys "DO NOT SHOOT THE MESSENGER" ::015::

that makes sense, you know at the dealership they just threw the battery in and fired it up.

First off thanks to all who have replied . I just completed checking all electrical connections and everything is tight and clean. After looking at the suggestions from you guys I'm inclined to believe there is a dead spot in the map. The bike did this in the first 300 miles a few times and then seemed fine and now at 6000 miles it seems to have started again. I know my bike and release and throtle are consistent. I just can't seem to pinpoint the circumstances that this occurs. I'm going to remap and see how it responds afterwords. I also checked stand switch and tip over switch all good. I will just be extra careful about pulling out in traffic from now on.Thanks again all. ::021::

Have you had the TB sync checked / air screws adjusted and / or the CO volume bumped up yet?

Doing this to my 2012 Cali bike pretty much eliminated the problem. The few times it has happened since then I can attribute to me messing up my timing.

Intake vacuum at idle is supposed to be 35 to 39 KPA. Mine was not (it was low) until I got the air screw adjustment right.

 

[Mikel]

Tube bender- no I have not adjusted air screws or throttle body sinc yet. Unfortunately the dealer in my area is not very helpful . I plan on doing it myself eventually . Your in my area maybe we can plan for lunch at the cafe in San Clemente sometime. I have not had a chance to talk to or ride with another tenere owner .

 

[tubebender]

I wasn't sure where you were located, but yeah, we could meet up. I'd be happy to help you out.
I have a Harmonizer. Used it on at least a 1/2 dozen Teneres here in So. Cal.

PM me with some dates and lets see what we can do.

The off idle stumble is a dead spot. It is caused by the throttle dampening. With the clutch lever in the ECU has no dampening and as you release the clutch and give it throttle, once the clutch switch opened the ECU burps a little and there is a big pause in the throttle.

The Clutch Jumper with a fuse will remove all of it and give you total control of your throttle.

An ECU reflash can change most of it also, see AVC8130 on this site

damping vs dampening. What is "absorbing" while the other is making things wet. good stuff.

Ok, time for a stupid question. WTF is an ETC? Mine has puked and sputtered when I gun it from day one. It coughs and knocks no matter what kind of gas I run through it. 2011 8,000 miles on it. garaged every night, milk and cookies.highway touring pavement queen.

 

[Scoobynut]

ETC = Etcetera. Also means Electronic Traction Control.

 

[autoteach]

Was going with Electronic Throttle Control. There really isn't any non-electronic traction control systems.

 

[yz454]

Yes there it.s called the right hand.

 

[autoteach]

No automated non electronic. I knew some dick would say something about what he does with his right hand...
