What the heck is up with all the complaints on the factory fueling/mapping? Why is a re-flash needed?

[ballisticexchris]

This fueling thing that lots of forum members are talking about puzzles the heck out of me? The OEM factory mapping is spot on and I can adjust the performance and throttling with proper gear selection and clutch use. I'm at the point that I can get the bike to run perfectly smooth with no lurching just below walking pace (in a straight line). I'm still struggling with lock to lock turning at slow speeds. But I'm of the opinion that is 100% rider issues.

Does anyone practice clutch use anymore? I know when I take my dirt bike in the mountains I never bother to re-jet. I just ride the thing. Sure it burbles a little bit, and can stall if I chop the throttle. With good throttle and clutch control I can have a pleasant trail ride.

The Super Tenere adjusts for elevation and is one of the most perfect fuel injected bikes I have ever ridden. I have also heard that the first three gears are limited. I have not experienced this. In sport mode the front wheel will loft up and motor will scream in 1st - 3rd. It idles at around 1000-1100 RPM and there is zero surge at any throttle setting. Did I happen to get one of the good bikes? Or is the CA model tuned better than the rest of the countries bikes?

It's twitchy as f**k.

 

[RCinNC]

I thought it was twitchy too in sport mode when I first got the bike, but that was more a question of training my throttle hand than a need to adjust the bike itself. I don't even notice it anymore; feels perfectly smooth to me.

 

[jeckyll]

Agreed, it's something that takes getting used to. When I switch between bikes a lot I notice it, when on a road trip I'm used to it quickly.

We must all be stupid

Sorry? How so?

Not necessarily but maybe "more money than sense" describes the symptoms better

 

[OldRider]

Seriously ballisticexchris, ride an S10 that has been flashed and report back. It's like night and day difference in how it runs in Sport mode.

There are three things in this discussion, with the first two being the stock bike.

1. The stock fueling for some bikes were so overly lean that the throttles could be twitchy and a number of people (me included) had the engine quit at low rpm. And this is after Yamaha improved it from the Gen1 bikes. A throttle body sync can help and for me it made the difference I needed when I moved to the Gen2.

2. Some bikes are not so cold-blooded and/or their owners just adapted to them and never felt they had an issue. There are examples in this thread.

3. Flashing, which installs a new electronic throttle map in the engine control unit, can make a big difference, even for bikes which seem fine. This is less in the Gen2 than in the Gen1, but there is improvement to be found and it will take care of the first point about stock fueling.


Note from management - You can attack the argument and bitch all you want, but do not attack other members.

Compared to what?

If you compare it to a nicely set-up carbureted bike, then yes, I agree, but it is much better than many other fuel infected bikes, although my Versys 1000 was the best I have ever ridden.

Emission laws call for reductions in gases, particulates, etc. One of the ways manufacturers approach this is to turn off fuel supply when the throttle is closed. With a carbed bike, fuel continues to flow and, this is important, fuel particles keep the inlet tract moist so that when you open the throttle, there is always a supply of fuel to mix with air and the throttle rolls on smoothly. With a fuel injected bike, there is no fuel supply on a closed throttle, the inlet tracts dry quickly so when you open the throttle, there is a moment when the engine is literally starved of fuel and that, combined with a lean mixture gives you that moment of snatchiness. Some people who re-write the fuel maps program the injectors to maintain a fuel supply on a closed throttle to eliminate that issue.

Hope this helps.

The issue is not anywhere near as noticeable when riding off road, at least not for me.
My previous 13 had the twitchy throttle issue but it seems even more noticeable on my new 18.
Is it a deal breaker no but it is annoying sometimes.
Slow speeds in town is where I notice it the most.
I read about lots of folks claiming having the ECM flashed was the best thing they ever did, I would love to take one of these supposedly greatly improved Tenere’s for a test ride and decide for myself if I’d like to have mine flashed.
But either way I’m pretty well satisfied with my Tenere.

You got lucky apparently

 

[Nikolajsen]

Use mine stock, no problems in either modes.
But I find "T" mode better of road, due to the "slower" reaction. In "S" mode small bumps, can make you turn trottle when you don't want it.

I think that most people who remap the S10 injection do so to reduce the engine brake, which curiously with 600 lbs + rider + passenger + luggage, the factories offer as a virtue the engine brake on an adv bike. As they also offer as a virtue, the management of the injection depending on the position of the throttle and the angle of inclination, in order to "reduce the engine brake" and avoid blocking the rear wheel "but" .... in the superbikes. that is, I think they know what they are doing in each case

 

[Sierra1]

.... Did I happen to get one of the good bikes? Or is the CA model tuned better than the rest of the countries bikes?

It would have to be WE got a good one....because YOURS sounds to be the same as MINE....and I'm in Texas, so.... To be fair, and objective, I don't believe it is fuel injected (FI) thing versus carbs. I've never had any other FI bike with a similar throttle response; Yamaha has definitely made it this way on purpose, not by accident. And, that being said, I wouldn't change a thing about the fuel delivery. I've assumed that "T" would be useful off road, like Mr Nikolajsen advised, and on surfaces with less than ideal traction like wet roads; for the "slower" response.

Compared to what else I current own.

Serious, my tuono feels quite a bit smoother.

Its alot easier to ride after the flash also less engine braking. Personally its worth the money. Especially as i find the stock suspension perfect for me so no need to spend anything on that. Horses for courses.

This. I had 10K miles on stock mapping before I had Anthony flash it....7K miles later and I can say it is a completely different animal. The non-linear mapping of throttle twist to throttle plate opening is not apparent until you flash the ecu with a 1:1 map for the first 3 gears. Only then do realize how limited/lagging the throttle response really was. If you think throttle-up wheelies are fun with the stock mapping, you'd be loving them with the remap.

As always, opinions are like assholes.......and this is mine.

 

[Sierra1]

I don't like wheelies; I know, I'm in the minority. In my opinion, it only lags in "T". And, I LOVE the heavy engine braking.

You and me both. I just happened to try a few spirited "drag race style" launches for fun on an empty section of highway and was impressed. With traction control off and in sport mode this baby has some impressive power that can get away from me. And the engine braking when wheeling through the canyons in sport mode helps me with holding a line.

It's also easier to accelerate from a stop without stalling (from poor clutch use) in sport mode. I think I remember you mentioning this a few threads back.
