This thread will discuss tuning the 2014 and up Super Tenere with the Dynojet Power Vision 3 and theDynojet C3 Tuning Software

The following information is provided for educational purposes only. Custom tuning may void your vehicles warranty, violate emissions laws, and cause catastrophic mechanical damage. Any tuning is done at your own risk.

I took a look at the PV3 in this thread
I ended up buying one and tuning my bike.

I developed a custom tune for both the EU and USA versions of the bike. I've run the USA tune now for 5000 miles and another forum member is using the EU tune in the UK. He helped a lot test driving and logging data. So the tunes have two positive evaluations on two bikes (well, two is better than one).

Changes to the stock tune include:
Custom Sports Mode Drive-by-Wire Throttle Tables (fun and not too aggressive, no power limitations in any gear)
Custom Touring Mode Drive-by-Wire Throttle Tables (great for off-road throttle control, no power limitations in any gear)
Modified Sports and Touring Mode Deceleration Engine Braking (smooth engine braking)
Custom Ignition Timing Map (great drivability and fuel economy, not advanced as to require better fuel than recommended by Yamaha)
Disabled Deceleration Fuel Cut (no jerky fuel on-off)
Custom Adaptive Learning Alpha N table (closed-loop economy cruising and great open-loop throttle response when you get on it)
Custom AFR Factor Alpha N Table (smooth transition from stoichiometric cruise to power enrichment)

Seems that a lot of technical detail just bores most people (and takes up my time), so, feel free to ask questions. I can go into any technical details as requested.

The tune files are attached and can be opened and used with the free C3 software linked above. You do not need to own a PV3 to use the software. The PV3 hardware is needed to flash your bike and log data as desired. The tunes are not locked and can be edited any way you like.

Hulkss, You might know the answer to this (or could test). Does the "eco" light on the dash indicate that fueling is in closed loop mode? Or does the eco light simply have a set of pre programmed parameters in the dash based on rpms and throttle position?

Reason I ask is while riding at up to 5k rpms with my ecu under light load the eco light is on, but there seems to be a drastic shift in mpgs around the 4200rpm mark as calculated by the dash.

I doubt that the "eco" indicator has anything to do with closed loop fuel control. It likely just indicates that fuel economy above some set mpg level. What tune file are you using?

Probably, the ECO light, is as it used to be in carburetor car to save fuel, it was indicated with lights on the dashboard that measure vacuum and rpm…..at a certain rpm, you must have a certain vacuum to turn on ECO… if you have more vacuum, ECO will also come on….but if at a certain rpm, you have less vacuum (more open throttle)….the ECO light will go off….At that time the system was called “ECONOSCOPE…and it was reported with lights (red/yellow/green)
Instantaneous consumption could be added to the calculation… but with vacuum and rpm it would be enough

Hola amigos;
Apreté el gatillo hoy; Acabo de actualizar la ecu hoy con PV3. Casi me cago en los pantalones mientras se escribía el programa desde el PV3 a la ECU...:eek:
por suerte todo salio bien y la moto salio del tunel de mas alla jaja...
Probé la moto hace unos minutos por mi pueblo y mi primera impresión es que el tuning Dynojet es mejor que el de serie, está bien, pero por el precio de la PV3 me gustaría probar tunings de otros usuarios. No quiero más potencia máxima o velocidad. Me gustaría conducir mi bicicleta de la manera más suave y con mayor par posible a bajas revoluciones y me gustaría un frenado del motor más suave.
La moto es un modelo europeo DP07 con el escape AKRAPOVIC construido exclusivamente para el Super Tenere con gato original y filtro de aire.
El archivo de stock guardado es el archivo llamado 2216004.stk
El archivo que usé en el flash fue el archivo llamado: Super Tenere 2216004 EU.djt
Hay un tercer archivo de sintonización en mi PV3 2216104.djt que está protegido por contraseña, ¿hay alguna contraseña estándar para esto?
¿Por qué este archivo está protegido con contraseña? ¿Es este un archivo asesino?IMG_20210611_111656.jpg

The tune you are using is very good. Put the bike in tour mode. You will still have full power in all gears with a very smooth throttle.

Good morning Hulkss;
I`m learning and trying to use the Power Core software.
Obviusly I´m working with a copy with the master tune file.

Im looking for the "adaptative learning tables" but I cant find it in the Power Core explorer.
I know im doing something wrong.

All in all im triyng to understand how the ecu works.

Hi again Hulkss, thanks for your time
I have read the entire thread, trying to familiarize myself with the concepts explained on it.
However I also try to familiarize myself with the Power Core software.
I can see the timing tables, the environment menu, and lots of things, but I'm stuck because I can't find the adaptive learning tables or a place where reduce the fuel cut on throttle release for smoother engine braking. I know I'm missing something along the way, or I just haven't loaded or enabled access to certain variables and so I can't find them.

On the other hand, I want to comment that I have flashed the ecu of the motorcycle with the tuning that is protected by password and that came in the memory of my brand new PV3.
Now the bike works how I want it to work but I don't know what is written in the tuning. I know that's playing Russian roulette but I wanted to know what was in that black box and I'm glad it works but Now I want to get to the same bike behavior but doing it myself, knowing what has changed and doing it safely by reverse engineering. So I want to start with small innocuous changes like motor braking or adaptive learning.


Sorry about the Google translation, I didn't have much time today and I wrote directly in Spanish using the Google translator.

The password is dynojet2018
Thank you!
The password is right!
However when comparing the stock .stk file with the dynojet .djt
It only shows two differences, the fan operating temperature and the engine rpm limit.
There has to be something else that makes the difference and I'm sure it's adaptive learning and motor braking but that table is nowhere to be found.

It appears that Dynojet may have updated their software to be emissions compliant, limiting what can be modified.

Use the tune from the first post in this thread. It is much improved over what Dynojet provides.

My Windows computer is down at the moment. When I get it fixed, I'll see if I still have the older Dynojet Software downloads.

If you open a tune file such as your .stk file you should see a list of folders on the left starting with Adaptive Learning, Airflow, Drive by Wire, Environment, Fuel, Rev and Speed Limits, Spark etc. If you click on each they expand showing the tables you can edit. Fuel cut and engine braking are in “Fuel” as I recall (I’m away at the moment, so I don’t have my old Windows laptop with me).

Thanks for your time again
As you can see in the picture, the list of folders begins with the airflow folder, as Hulkss says, it is possible that due to some European environmental restriction, they have made adaptive learning disappear from the list. You can even see the entries modified from stock because they appear in bold but nothing about adaptive learning and engine braking...
I'm curious if anyone else in Europe or even the UK suffers from this anomaly.
It doesn't matter what type of file I open, .stk or .djt, I can't even see it complete by loading a USA file.
My last hope is to download a US or UK version of the Power Core software, assuming the restriction is in the software and not the file.
I have used two versions of the software with the same result

I suggest you uninstall Power Core and reinstall the old v2 you have, then disregard the update request when it pops up and continue to ignore it each time you open the software. Hopefully you will still see Adaptive Learning in Explorer. I have not updated my software from v2 and Adaptive Learning was still available to edit a couple of weeks ago. Dynojet have introduced a “Professional” version of the Power Core software for licenced Dynojet dyno tuners that includes all of the tables and functionality in v2, and a more restricted v3 version for the public. It’s disgraceful of them to reduce the functionality of the product we have bought.

Congratulations dear colleagues!

I just fixed it by uninstalling and reinstalling V2 of the software.
You were right Pooh and you weren't going wrong at all Hulkss!
Now I can start using the application with dignity.
I reiterate my gratitude, I owe you a few beers

Hi folks;
I ve been playing with the PV3 last weekend and now I have a couple of questions.

Sorry for asking the same thing again Hulkss!
I have a little doubt left:
Can the official YAMAHA workshop read and write an ECU flashed with PV3?
Can the official YAMAHA workshop return the bike to stock if I order it?
I ask this again because I must know the consequences of losing or damaging the PV3 in the future.

Another question: What about the throttle enrichment low, transition and high gear tables? (not the acceleration enrichment)
What is the aim of this? Is this linked to the deceleration or engine braking? If not; Could be used to compensate the lean AFR at closed loop
overlapping adaptive learning tables?

And the last question: monitoring the ecu with the pv3 I have observed that the TPS does not read zero with the motorcycle off and the twist grip at zero, is that correct? Or do I have to recalibrate the TPS?


Cheers!

I'm not familiar with what their capability is. I also do not know how a flashed ECU may affect a warranty.

overlapping adaptive learning tables?

I have not worked much with those tables. The AFR during closed loop or adaptive learning operation is not too lean. It is where it should be to work with the narrow band O2 sensors. The fuel mixture is only near stoichiometric during steady state cruise. As soon as you twist the throttle, the mixture is immediately enriched.

And the last question: monitoring the ecu with the pv3 I have observed that the TPS does not read zero with the motorcycle off and the twist grip at zero, is that correct? Or do I have to recalibrate the TPS?

If your idle rpm is ok and there is not an excessive dead-band near closed throttle, I would not change it.

In the service manual, I do not remember having read that the service manual recommends (in the event of a problem) to the official Yamaha mechanic "delete the software and reload a software again"…..if it reads repeatedly that if there is a problem….change the ECU…so I don't think they have the ability or the means to upload the original software again
