Anybody have experience with Rexxer? What would be the difference from Tuneboy, Rapidbike, etc?

My bike is the euro version with shotgun side exhaust. Had an oil change at my dealer last week and the lead Ducati tech saw my bike and suggested we remove the catalytic converter, exhaust valve servo motor and get some custom mid-pipes made since I already installed a free flowing slip-on muffler. ECU was tuned using Rexxer. Not sure though what map was used, I wasn't there when they flashed the ecu.

Bike was totally transformed into a different bike! Exhaust sound is louder, but not obnoxiously loud, and significantly deeper than stock die to the removal of the cat. Engine is so much smoother now through the whole rev range. Low rpm shuddering/jerkiness is pretty much gone! Previously I needed to feather the clutch everytime I reach low speeds <30km/h. Now I can almost reach full stop before needing to pull on the clutch to avoid stalling. Extremely happy with the outcome! Unfortunately we don't have a dyno facility available locally to see the power gains or to further fine tune the bike. Very excited to do some track days to see the weight saving benefits too!

The difference among these solutions is that the RapidBike module piggybacks the ECU and intercepts the signal controlling the fueling so that the stock mapping is not changed and the device makes adjustments based on engine and atmospheric feedback.

However, Rexxer and Tuneboy flash the ECU and make permanent changes to the fuel mapping stored in the ECU itself, so you no longer have the Ducati stock or RACE configuration. Rexxer flashes are typically performed by a vendor by sending them your ECU or in your case, hands on with the bike. Tuneboy will provide a basic map based on your engine, filter, and exhaust then with the hardware provided, you upload changes using a PC and the Tuneboy software. Additionally, Tuneboy has various options to allow one to add cruise control, blipping, etc.

With the RapidBike module, to go back to stock, you simply remove the device. With Rexxer and Tuneboy, the stock maps must be flash, or reapplied, to your ECU to take affect.

@sinjin,

The RapidBike - being autotune, it will constantly retune itself to work optimally based on feedback from the engine, correct?
And only a module is required, no ECU flash? So basically it would not void warranty, as you can simply remove it, should you experience any problems? Or would Ducati be able to see that it has been installed?

Indeed. The RapidBike EVO Rapidbike Evo | DIMSPORT - ENGINE CALIBRATION SPECIALISTS is auto-adaptive and will constantly adjust while riding. I understand that it takes roughly 100 miles after installation to get close to being dialed in.

Jarelj, the GM / owner of Ducati Omaha, confirmed that by removing the module, the bike immediately goes back to the tune in the ECU, whether that is stock, having the RACE map enabled, or a flash, and is undetectable as being installed in the first place.

Many folks tout the benefits of a tune and flash, however the warranty on these bikes is far more valuable to me than squeezing an additional 3 or 4 HP for street and track usage. If this were a race bike and the warranty was completely voided, I would be less reluctant to manage the fueling myself.

This being said, I am not sure how much visibility the DDS has in determining whether the ECU has been flashed and flashed back to stock mapping and whether or not applying changes to the ECU will leave behind a footprint or time stamp of revisions or changes.

Thanks a lot for the wealth of information you shared! It's nice to know the differences of the tuning options we have.

In my case the dealer offered and did the tune so they'll pretty much cover any warranty issues. I paid them after all for the tuning service.

I guess for DIY jobs Rapidbike is a great option for it's ease of use and it's constant recalibration while riding.

Next question on my mind then is which is the best route to take? Do performance benefits greatly differ from one company to another or are they very minimal because compared to stock, all of them pretty much improves the bike's performance. Is there an option better for street riding and another for race setups? Or is it just a matter of which is readily available to us?

Full disclosure... I am not an authority, however I have been around the block on my Ducati a few times.

So, the RapidBike is a great option for your typical owner because if you change or modify the exhaust, upgrade the filter, or decide to remove the device altogether, it is not terribly intrusive and fairly straight forward to install and remove. It is extremely effective at removing the hesitation and limitations introduced to the bike for the purpose of meeting environmental regulations.

The Tuneboy, Rexxer, or a flash as a result of tuning on a dyno, will allow you to fine tune the mapping to ensure an optimized, custom, high performing AFR to match your exhaust, filter, and unique engine. Though, any changes to the configuration will require further tweaking and a review of the settings resulting in a reflash of the ECU.

In your case, by having the dealer perform the changes to the bike, they are accepting the responsibility for any potential engine issues that are no longer covered by Ducati as a result. It becomes very sketchy and a gray area when you have your dealer install the parts or you perform the work yourself and a 3rd party performs the tune or you configure it on your PC, as then you can have finger pointing if something goes wrong.

I suppose it is synonymous to buying a track suit off the shelf vs having one tailored for you.

Hi Moyski,

What exhaust do you have and what you replace the original cat with? I have also the Euro4 exhaust.

@sinjin,

Thanks a lot.
I recognize that you're not necessarily an authority, but I've seen enough of your posts on the forum to trust your advice, LOL.

I would do it even if the HP difference was zero. The bike runs too lean stock. With proper fuel mapping the bike runs amazing.

I Flash my bike with Tuneboy at 2800kms. Im now 21000km. The DDS doesnt know if the ECU has a Flash. Even with Ducatis Updates I havnt had a problem.
Warranty is a funny subject. Ive had warranty jobs done on my bike with a number of mods in which forum experts say would void warranty eg: I installed my own Mag clutch cover and 1299 slipper, yet I had water pump replaced under warranty.
I all depends on the dealership......
There is risk in any mod you do. Thats half the fun.

Hi Moyski,



What exhaust do you have and what you replace the original cat with? I have also the Euro4 exhaust.

I got the muffler from Delkevic UK. They have several options for style, length and material of muffler. The midpipe was done by a local fabricator, cost me about $300.

Total cost is less than 1/3 the price of the full Akrapovic system. Well worth it in my opinion!

After feeling the difference of a stock bike vs a tuned bike, I would not hesitate doing it again even if there is no horsepower gains! The bike is so much more enjoyable to ride now even at slow speeds!

 

[sinjin]

My point, was that with the RapidBike or by unlocking the Ducati provided RACE map, you can realize similar improvements to the fueling rather than flashing the ECU and by doing so, it carries far less risk.

I can't speak for everyone's experience or relationship with their dealer, but I was informed that Ducati can perform a deep dive past the typical diagnostics and see a lot more than one realizes.

If you are willing to risk a warranty denial if your dealer doesn't support you, then please do as you wish to your bike.

Done.

Thanks Moyski!

Do you have a picture of the midpipe so I can check with my local dealer?

Rexxer expierience

Hi there my Rexxer expierience is quite a sad one. 7 times of use in 2 1/2 years and display did not work any more. They wanted 300€ for replacement even so they offered whole new thing on Ebay for less. So what i can say about Rexxer is a good driving performance with a very poor service and quality moral.



Hope i could help

@ducati996
Nice intro.

I have both a Rexxer flash and a Rapidbike with big improvements on both counts. No issues.
I also have nothing but praise from both David @RX and Yaman @RB.
Their service and communication are second to none. Sorry to read about your misadventure.
