Hello guys!

I got a DS 2020 2 weeks ago (my first Ducati) and I'm very stoked with the bike. My only concern as many of you is the lack of a more aggressive sound.

I was two clicks away from ordering an Arrow Exhaust until I realized that the Scrambler has a lean mixture and removing the cat would worsen this situation (adding that is an air-cooled bike). Then I noticed that a lot of people were re-mapping the scrambler at the time of changing the exhaust for an aftermarket one.

Even tho there is a lot of content about this topic, most of this content is for "older" bikes and mine is 2020. I wonder whether the lean mixture is still an issue for the newer ones. I guess that is worst because of EURO V but who knows.

If that is the case, I was planning to order the Arrow and a Rexxer EVO in order to do the mapping.

As a note, I'm from Chile and with respect to emissions, we are in EURO III.

Any advice?

Thanks!!!!!

I have the Arrow however it was installed by first owner and he didn't have it flashed.
I think the bike can adjust on the lean setting via computer but I'm not the guy to ask.
I'd have the dealer do the work, I live the look of stock pipes and may actually switch mine back out but will ask dealer in Springtime.
Mine is first year 2017 803cc.

Hello, if its a 2020 I think you can use the Termignoni UpMap device and software, check it out.

UpMap KIT T800 and Ducati cable

Kit UpMap for reprogramming the motorbike engine control unit

UpMap T800 - Ducati Scrambler 800 E4 Icon & Full Throttle - Upmap

It took a long time, but in the end it was worth it … By popular demand, here are the maps for Ducati Scrambler 800 E4 for the Icon version and Full Throttle, also for the 35kw version. Soon we will also extend to other Scrambler models such as Icon DarK, Desert Sled and Caffè

I don't know anyone that has used this but it seems pretty interesting. You could be the first to post about it

Interesting! Do you know if this is going to work on an Arrow Exhaust?

Sadly it is out of stock.

I just ordered the Arrow Exhaust. Yesterday I went to the local Ducati and they offered me to map the bike for 200 bucks. I told this to David from Rexxer and he say that the mapping provided by Ducati is not going to make the mixture richer because it comes from Ducati. I don't know what to think.

Might be too late on this, but you can cut the baffles out of that stock termi exhaust to get a much better sound if you are only looking to improve the sound. I did it on mine and love it for the price of $0.00.

As I understand it grifo, it has got even leaner. I own a 2017 model and got it dyno'd and the graph of existing to remap was chalk and cheese in terms of how lean stock is to modified. Once you pull the CAT off changes everything. The CAT weighs around 5 kilo so ditching it is the way to go then get someone with a dyno to remap it properly. No idea what Oz is for Euro levels, don't really care as the footprint is so tiny for carbon emissions.

But stock exhaust is not termi 🤔

But stock exhaust is not termi 🤔

If I'm not mistaken, your 2020 DS comes with the stock exhaust that has twin baffles with a black heat shield originally found on the earlier FT and Cafe models? That particular style of stock exhaust is known as the "termi" exhaust because it was branded as such back when it was put on the FT and Cafe models. Not to be confused with an actual aftermarket Termignoni exhaust. The stock termi still has the cat and other emissions restrictions of course, it supposedly has a slightly better sound than the normal stock exhaust but no performance advantage.

So, if you want to derestrict your exhaust flow and get the performance gains as well as the better sound you do need to buy a new full exhaust. But, if you just want to make your bike sound like a motorcycle and not a sewing machine, you can simply cut out the guts of the two baffles on your stock setup.

Grifo, maybe you have already sorted your stuff out by now. But in case you are still wondering what to do here is my experience. I put a Unit Garage full decat exhaust in my 2017 model. Added a K&N open filter and the performance improved a lot in medium and high ranges. A guy from Ducati here in Madrid advise me to remap because the engine was going to be damaged in the long term. Called Unit Garage Italy and they said no need at all for remaping. Two years after having installing this exhaust I am nothing but happy. No problem has raised and the bike is faster and more responsive than the stock. Do not recommend the Upmap from Termignoni. It is a map made in the factory at a given temperature and altitude msl that could change a lot in your country. In my opinion an adaptative unit give out better results. I´m using a Rapid Bike Evo unit in other bike and it works very well. It take in account the variables in a given moment and place, and implement that in the injectors and Lambda instantly. Imagine that Rexxer Evo works same way. But as I said, didn´t do anything in the Desert Sled and it performs very, very, well.

I took the CAT off and took it to a Dyno where it showed it was running real lean. He remapped it to preserve the internals long term and it gave it more torque off the line. The rest was virtually unchanged.

The stock bike is already lean, but after reading you, passing through a Dyno I´m wondering to do the same because my case could be really worse.
Not just I took the cat off but, in addition, installed a K&N open filter.
That means that more fresh air are coming in, per second, and the mix between air and fuel could increase.
I guess that the stock comes about 14,5.
I´m not an expert, but guess this can induce higher temperatures in cylinders and a premature worn out.
I was quiet because of the advise of Unit Garage.
But think will be wiser going to a Dyno, 10 km from home, and see what´s going on.
One question to you Memla, did you need to add any booster plug or other brand unit to remap your bike?
Thanks for your help.

No just took it to the Dyno guy he knew the motor well as it has been around a while now. He just tweaked the computer settings and showed me the read outs. I also put a quicker turn throttle on it so it is much more responsive. Wasn't cheap but he said it was waaay to lean for long term health.

 

[Inakibil]

Thanks Memla. Today I have been in the Dyno shop.
They said that the stock ECU is fully locked in Ducati Scramblers and it is not possible to remap/flash them.
The only option is putting something like Rexxer, Rapid Bike...etc additional units that can "lie" the stock ECU.
That option is the best in our case, but bit expensive, about 700 euros. The cheaper way is using a Booster Plug to tell the "resident" ECU that the temperature is much lower than real, then the injectors will send more fuel, an the mixture will be richer.
I advise you to be really sure that your Dyno really built a new map in your ECU while it is not possible to write anyting in it. Do you have the old and new values?
I have also ordered a 600xx cam fromG2, waiting to arrive.

Mine is a 2016 model so maybe different. Had old and new on the graphs he showed me so will check with him. That throttle cam is great you will love it. I had to put one of those extra units on an MT 09 I had and it worked a treat with the CAT off and new pipe/air filter it wasn't that much and was just a little circuit thingy with some lights. I think $300 OZ dollars so cheap as chips for you guys.

 

[Inakibil]

I don´t know. Here in Europe the Desert Sled was first released in 2017, when I purchased mine.
Anyway, if the Dyno has worked out yours with a new map maybe it exist a back door my coleague don´t know.
If this is the case would be interesting to know if there is a trick to flash that ECU some way.
Do your new graphs show the old and new figure for air-fuel ratio (stoichiometric)? This is the core.

 

[h.grenade]

I got the arrow as well with the Termi upMap. I have not mapped it yet and it does pop on decel like a beast. The dealer said that the upMap will fix that and make it little better off idle.

I can't believe that I am going to say this (i love loud bikes) but I will be putting the baffles into the arrow, it is just too damn loud. I cant even ride without earplugs right now haha

Edit: my DS is the 2020 as well

 

[Bearcrawl]

I just did the Termi upMap last week on my 17' DS with Mivv open pipe no cat and a K&N. I did notice a difference. Still pops a little on decel but noticeably less. Also feels stronger at low revs. Seems like a worthy upgrade. Pipe is still loud AF but I am working on it. Tried 3 different baffles but nothing fit yet....

Do not recommend the Upmap from Termignoni. It is a map made in the factory at a given temperature and altitude msl that could change a lot in your country. In my opinion an adaptative unit give out better results.

** cough**

Any engine ECU is adaptive by itself and makes constant corrections for ambient air pressure (altitude), temperature, and rpm, crankshaft position and a few other parameters. That's how they work. An Upmap changes the fuel injection and ignition timing based on changed parameter tables in the ECU. It's still adaptive to elevation, air pressure, etc.

A Rapid Bike Evo on the other hand is a piggy back unit, which intelligently "fools" the stock ECU.

I'm not suggesting one gives better result than the other, but a changed map in the stock ECU is a more elegant solution and typically offers more options as a tuner. Unfortunately, not all ECU's are easily accessible for tuners and that's when piggy back units come in handy.

Yes , you´re right, any modern ECU has adds-on to mesure several things, including air pressure, oil temperature and so on.
What I wanted to say, from my little knowledge about this subject, is the difference from an Upmap, made in the factory for a given model of engine and exhaust , that has to work with a range of them in the field, at all altitudes and weather conditions in an almost generic way, and a Rapid Bike Evo piggy back.
That module first learn about your way of riding, and your bike, besides other things.
For doing this, the Rapid Bike needs at least 200km "watching" your mods.
Then the module make changes that can vary from winter to summer , altitude, etc, adapted to your specific bike and the to the air/fuel value you set before.
I installed a R.B.Evo in another bike, not the Desert Sled, and every 200Km+/-, I had to go to the shop (also a Dyno shop) to make new adjustments.
They set a new stoichiometric (far from the stock) value of 13.4, and the R.B. was progressively creating a new map every new visit, till the moment they said we got the optimum for my bike.
They also said that in summer time would be interesting to check again, and likely change, some values in the present map due to the high temperatures we experience here in central Spain.
This is what I understood from the explanations ,the guys from the shop gave me.
Maybe I got wrong concepts or I have misunderstood something, but, well, I´m still ready to learn, and thanks any help.
