Yes, the device is updated and activated with software you download to your PC. Any file revisions can be emailed and uploaded to the handheld to implement into the motorcycle.

I don't have a Panigale V4... yet, but I cannot be happier with the Bren Tuning flash they made for my 1199. It's not just about the top end power as I ride mostly on the street. The flash made the throttle very smooth all across the power band, and impoved the low to mid-range torque more than I thought was possible. I am in no way affiliated with them, just saying, they are good people. I had a lot of questions and they answered each and every one politely and promptly. Can't say that about too many motorcycle companies. In my opinion this is a no-brainer and will be one of the first things I do for my V4.

***UPDATE 05/11/19***


As promised I got the data for the throttle restrictions and the Termi AFR curve vs stock.



Thottle Restrictions


You can see Ducati does not command 100% throttle in the ECU. This is much like how the V4R is restricted without the race kit. The BrenTuning Flash opens up commanded throttle even more to give you the power delivery it was meant to have without restrictions for emissions, etc.

Throttle unrestricted in race and non-race modes. This is a new option for people that want full power at only a commanded 90-100% throttle. Or if they want the same throttle map without aggressive traction control. This gives the user more pliability because they can adjust the traction on the bike without a loss in throttle or power in the ECU.



This represents the stock throttle mapping




This represents the BrenTuning Flashed throttle mapping





Termi T800 Mapping AFR (Air/Fuel Ratio) Data



This dyno graph below represents power, torque and AFR. This is a comparison between the stock file with slip-on exhaust and Termi's own T800 slip-on UpMap. You can see the Termi DOES make more power up top than stock.. but also loses power down low and seems to match power to about 10,000 RPM. Now most of us aren't riding at 10,000 RPM a lot of the time so just cruising around, there's no difference between the Termi mapping and the stock mapping. The only difference you would actually feel is above 10,000 RPM. So basically track riders.

You can see the AFR isn't that happy. There are 4 AFR (air/fuel ratio) lines at the bottom of the graph. These 4 lines represent front and rear banks. You can see how far off they are from each other when they should be a lot closer. To the left you can see the AFR point value. The AFR jumps to over 16.0 on one bank (extremely lean). As you can see the power curve follows those lean spikes with a massive power dip. This is why when people add slip-on exhaust, they feel they lose power down low. The bike can't make power being this lean.






Akra AFR (Air/Fuel Ratio) Data


Akra is better mapping than the Termi mapping. You can see below that the AFR data on the rear bank is spot on!.. But it doesn't trim for the front bank and you can see that get lean.

With BrenTuning you get AFR corrections for front and rear banks to make more power.





Timing Tables

Like most Ducatis, BrenTuning found the stock timing maps work pretty well on 91 and 93 octane pump gas. They have seen very little gain on advancing it but usually do so on bikes in-house with real-time datalogging and a perfect fuel mixture. Akrapovic maps are heavily timing retarded on full throttle. On MR12 the bike will make 10-12hp in some cases utilizing the factory ignition map so it's not undertimed by any means. Akra mapping is a more complete tune. The Termi mapping appears to use factory ignition and load targets with some very minor changes. I DO NOT RECOMMEND TERMI MAPPING.

With the ARK mapping is the throttle trim increased to 100% like the Bren tune?

Do these bikes command throttle based on torque management like modern cars do? Could Ducati be holding back throttle % for durability reasons?

Like the V4R without the race kit, the V4 is also neutered due to emissions and EU4 regs. It's easier to kill power through the software to adhere to regulations rather than build a new bike to comply.

I hope brentune comes out with a package with a slip on, I'm ready. 1300 is a lot for a tune by itself.

When will you be testing the stock muffler?

No, Akra and Termi both do not touch throttle limitations. This is buried in the ECU and quite hard to define. Termi throws a bunch of timing at it with bad fueling and a higher rev limit. Akra takes away timing with better fueling and higher rev limit. Stock these bikes are timed pretty well.

Talks are in works for several exhaust manufacturers to include the flash with their slip-on.

So is the flash being sold now? What’s the advantage to bringing the bike to you to have it tuned there vs. a ship out tune? I know it would be more dialed in for that specific bike but wouldn’t it be close enough?
