STAGE 2 IS HERE

Following the release of our wildly popular Stage 1 Flash we needed to sit down and really start to look at what the 2020 truly has to offer.  Anyone with our Stage 1 Flash will tell you how much it improved acceleration, got rid of the now infamous “dead spot”, fixed the OEM idle issues, and made the motorcycle feel better and more smooth overall.  Stage 2 has months of research and development behind it as well as datalogging and dyno testing.  The new 2020 S1000RR is familiar to us but also completely changed.  To that end we were able define new ECU strategies that we can help make this already impressive bike even more impressive.   Stage 2 is a feature map making the bike more consistent, more reliable, and smoother and combined with our IAT Relocation and flap delete kit results in a much improved motorcycle!  (All Stage 1 Flash features are included in our Stage 2 Flash)

 

BENEFITS OVER STAGE 1
(CLICK HERE TO SEE STAGE 1 DETAILS)

Octane adjustments for auto adaptation on pump gas for US and international fuels 91-94 octane 95-100 RON.  Utilizing the multiple ignition maps and factory widebands, we are able to increase performance based on knock detection.  This also means if you have some bad fuel, the motorcycle will still compensate and put the bike into safety mapping just like the OEM ECU would.  This ensures your bike stays consistent and reliable.

Corrected cold/warm start idle to 2015 RR levels, finer tuning beyond Stage 1.  Stage 1 did a lot to correct the startup issues the 2020 S1000RR was having.  Stage 2 goes a step further.  There is no longer a high idle that transitions into a lower idle.  The idle remains static without any lean popping, idle hunting or stalling (see comparison video below).

Re-calibrated timing for higher octanes to make use of race fuels on same tune.  The 2020 S1000RR has multiple ignition maps and based on knock feedback, the bike will start to adjust to different timing maps.  This means if you have a high octane fuel in the bike or race fuel and knock isn’t present, the bike will transition to a more aggressive timing map automatically.  A more aggressive timing map will safely allow the bike to make more power. No more flashing every time you want to use race gas although we can still provide specific race fuel mapping designed to be used on ONLY race gas.  This feature is most beneficial when you are on the track or street and don’t have your handheld available to swap maps.

Lower max lambda, leaner high RPM Target for a few more horsepower.  AFR (air/fuel ratio) adjustments have been made to Stage 2 to be more aggressive to get a little more power out of the bike while remaining safe.

Higher RPM limit without throttle cut for roll racers *optional* (invisible – without storing event, for diagnostic purposes).  With Stage 2 we are able to raise the RPM limiter to 15,000 RPM while also making sure the raised RPM event is not stored in the ECU (for diagnostic purposes).  We have also adjusted the spark and fuel cuts so when the rev limit is hit, the bike doesn’t feel like you slammed on the brakes, it’s more gentle now.

30% faster up and downshifts over Stage 1 and now allows the use of fast shift sensor products on the market if desired.

BRENTUNING MOTO IAT RELOCATION AND FLAPPER KIT

As many of our customers know, our IAT (Intake Air Temperature) Kit for the 10-19 BMW S1000RR has been extremely popular and shows noticeable gains on the street and even dyno.  This IAT strategy was first used by Dinan (BMW) in the 1990’s.  However, the 2020 S1000RR included some serious changes and required a new strategy for this project.

New for 2020 is our Intake Flapper Removal Kit.  The 2020 S1000RR now has flappers in the intake tract, these flappers only allow a small amount of air to pass through to the engine until 6000 RPM when the flappers finally open.  When the flaps aren’t open it allows for stagnant, hot air to raise IAT readings and block air flow to the engine.  Hot air and low airflow equals less power.  This is why we developed our IAT kit years ago.  The flapper delete is just an add-on progression to the new model.  From scratch we developed block off plates and a whole new IAT relocation kit as the harness has changed from the 10-19 models.  All parts fit very snug and are made from billet aluminum for weight consideration and longevity.

The new airbox “flapper” design was made to reduce engine noise at low RPM’s.  Instead of the previous foam restrictor that we saw in the 17-19 models, the 2020 S1000RR almost completely closes off the airbox in certain scenarios.  This lack of airflow leads to very high intake temperatures.  The ECU’s strategy is designed around this “heat soak”.  Timing retard is based on a “per gear” and “per RPM” strategy and will not taper off until higher gears due to the airflow and RPM needed to open the flappers.  This is vastly different than previous years and more similar to the BMW GS1200’s (which also benefited greatly from this kind of relocation).  The first half of the throttle angles (0-50% throttle, commanded) and first three gears are heavily timing retarded on the stock calibration.  This is due to hot and stagnant air that sits in the airbox while the flappers stay closed.  The design of the OEM flapper servo creates an unnecessary bottleneck of airflow inside the airbox at higher speeds.  This distributes air to the inner most cylinders, negating performance and the maximum “ram air” effect the factory airbox can provide.

Our first kits have been installed and successfully tested with positive reviews on the street and track!  The bike doesn’t feel as lazy from a dead stop anymore.  The induction noise is superb after the installation/removal and compliments the essence of what a S1000RR should sound like; a true race bike.  The IAT Kit allows for consistent power at all RPMs and gears instead of waiting for higher gears to get additional, rated power.  During our testing on the dyno and per gear / per RPM datalogging, we found many delays in the factory ignition to combat the heat soak the factory airbox flappers create.  With our flapper delete and relocated IAT sensor, the bike reacted sharp from a dead stop and in lower gears / speeds (pre-6000 RPM cruising) without knock detection.

Getting a true ambient temperature from the front of the bike is much better than getting temperature readings from its original location on top of the engine with the flapper doors shut.  Idling at the starting line, pits or at a street light on a 100 degree day will put the bike into a temperature protect mode and pull power out to “save itself” until the IAT sensor reads accurate ambient air temp once the bike starts moving.  True ambient temps help the bike deliver more power and stay consistent in racing conditions.  We are not tricking the sensor but simply allowing it to read proper temperatures of the outside air.

WHY IS THIS MORE EXPENSIVE THAN PREVIOUS YEARS?

Unlike previous S1000RR models, the 2020 S1000RR requires more parts and a software update to ensure maximum performance.  Without one of these components you will have issues with your motorcycle.

With the IAT and Flapper Delete Kit there also needs to be a BrenTuning Moto Stage 2 Flash update.  This update is to maximize performance of the IAT and Flapper Delete Kit.

If you do not have the BrenTuning Moto Flash already, CLICK HERE TO PURCHASE AND SEE DETAILS.

WHAT DOES THIS KIT DO?

– Relocates the Intake Air Temp (IAT) sensor and removes the airbox “flappers”.
– Moves the IAT sensor from the factory location near the cylinder head to the front of the bike to get a true ambient reading.
– Removes factory airbox flappers to allow fresh air to enter the airbox at any speed, RPM or gear.
– A true ambient reading means more power but also means consistent power.
– Noticeable improvements in stop-and-go traffic, starting a race from a stop and exiting the pit.
– Even distribution of air to all cylinders without any cylinder bias.
– More air to the engine with plastic flappers removed.
– No downside and dyno proven gains across the powerband (see dyno chart below).

WHAT’S INCLUDED?

– Stage 2 Flash With Airbox Update To Maximize IAT and Flapper Delete Performance
– (1) IAT Extension Harness
– (1) Billet Aluminum Plug For Original IAT Sensor Location
– (1) Flapper Servo Block-Off
– (3) Billet Aluminum Plugs For The Airbox (Two Small and One Large)

DYNO PROVEN
(CLICK HERE TO SEE DYNO CHARTS FOR STOCK VS STAGE 1)

IAT 110F vs. 60F test with and without removing airbox flaps and IAT relocation (tested on a 55F ambient day).  Bike used was a 2020 S1000RR using our stage 1 flash with exhaust and 93 octane fuel on all runs.

As noted previously, the 2020 has airbox flappers that stay mostly shut, feeding no fresh air and heatsoaking the bike’s airbox below 6000RPM.  The stock calibration has compensated as a result.  This is a back to back run after only relocating the IAT to the nose of the bike instead of its standard location.  This is much different than previous years ECU strategy.  We converted it back to previous years strategy to optimize performance.  With this kit installed, it’s mandatory to run our Stage 2 Flash for smooth performance.

As you can see both runs, before and after IAT install, have the same exact AFR (air/fuel ratio).  It’s a common misconception that IAT modifications adjust fuel.  They do not do that.  This bike is fully closed loop and hits our commanded lambda target every time due to BMW’s OEM wideband oxygen sensor technology.  You can see pretty steady HP gains across the entire RPM range. Converting it very similarly to a 2015-2016 style S1000RR airbox (derestricted years).  While the dyno graphs show gains, results on the street or track are actually better when you are hitting higher speeds and it creates a more noticeable ram-air effect.

 

IAT RELOCATION AND FLAPPER INSTALLATION VIDEO

Total install time: 2 – 2.5 hours

 


**OPTIONAL**

Cut and smooth the airbox exteriors for maximum performance. (see before and after photo) of airbox with flappers out and one with grinding.  Please note that once cut, you are not able to return to stock as the flapper system cannot be installed again.

BRENTUNING MOTO ENGINE PLATE KIT (optional)

The BrenTuning Moto Engine Plate Kit installs to the engines valve cover and airbox.  These pieces are custom CNC billet aluminium and made for a perfect fit.  Each piece has our logo engraved in a black color (only color option).

ADVANTAGES

– Reduce weight from motorcycle
– Smoother startup
– More accurate AFR (air/fuel ratio) readings

NOTE: This modification is not required with the Stage 2 upgrade.  This modification will not add power to your motorcycle.  This modification is for competition use only.

HANDHELD TUNER

 

WHAT IS A HANDHELD TUNER AND WHAT ARE THE BENEFITS OF HAVING ONE?

We start with our popular OBDII Flasher+ and fully customize it.  Thoroughly tested by our own engineers, not just for its function but also durability.  We purposefully dropped this thing about 100 times just to make sure if you accidentally dropped it, it would still be a usable device.

So why buy it when you can just send in your ECU for flashing and spend less? Let’s see the breakdown.


NO DOWNTIME

No need to send in your ECU or remove it from your bike at all.  You order the handheld, it get’s delivered to you, you flash your bike.  You never miss a day of riding and no effort removing the ECU.

 

STORE MULTIPLE MAPS

When you send in your ECU, you only get one map.  You might be thinking, “why would I need more than one map?”.  Storing multiple maps means you’re able to flash for different fuels.  If you’re a serious track competitor, we can work with you to get you different mapping for different tracks.  If, for example, you’re add an exhaust to your stock bike, we can email you a file that takes the new exhaust into account with the changes you need to optimize your S1000RR’s new modifications.

 

GO BACK TO STOCK ANYTIME

Not only can you store multiple race maps, you can also flash the original, stock file back into the bike at any time and for any reason.

 

READ AND CLEAR ENGINE CODES

If for some reason you have an engine light, you’re able to plug in our handheld tuner and read the codes from it.  Using the codes you’re able to determine the issue with the bike.  Sometimes these codes make the Engine Light come on.  Even after the issue is fixed the engine light can stay on for a dealer to clear or stay on for a certain amount of key cycles.  The handheld can clear these codes.  As long as the issue is fixed, the handheld will eliminate the engine light.

 

HOW IT WORKS

A pretty easy step by step on how the flasher works for the 2020 S1000RR.  This video is for map loading, we will detail the original file download in the future.

 

 


 

**This product requires previous purchase of our Stage 1 flash with handheld and preferably a FULL Akrapovic
exhaust system (best power), OR you can purchase a handheld from our dropdown menu for this product**

***DISCLAIMER: FOR CLOSED COURSE COMPETITION USE ONLY.
NOT INTENDED FOR STREET USE***

 


 

**** Our handheld tuning device requires the use of a windows based computer. The handheld and the computer never need to be next to each other and the software is non-invasive. This means a desktop or work computer should be just fine. The file download for the software is around 60MB which you will have to download from the internet. If you do not have access to a windows computer, the internet or are not proficient with a computer and downloading / uploading things from the internet, please consider our mail in ECU tuning service. ****

**** Two fuel options/maps are available with your purchase, we can do a low octane and high octane option, if you have additional requests they can be included at an additional $100/per map fee, this can cover additional fuel qualities or modification sets. ****

**** Please for best results, make sure your motorcycle has been updated at the dealer to newest software available before purchase. If the bike is under warranty, this will be a free update. If the bike is out of warranty they will charge (1) hour labor to do this. This will avoid any issues with future updates (for the most part) and avoid us having to remap the bike for new software. A $100 remap fee will be charged for new mapping after a dealer updates your ECU. Please always put the handheld back to stock before bringing to the dealer for any updates, to avoid unlocking charges on the handheld. ****

****All HP numbers provided are done with an Akrapovic Full System exhaust, this is the best exhaust on the market and provides the best HP results. Using other exhausts on the market is possible and mapping has been developed, but numbers will not be as high as you’ll see with Akrapovic. We exclusively recommend Akrapovic.****

    Andy Young - Maryland Aug 28, 2018
  • “ This product is amazing.  I feel like I have a better version of my bike.  Like it should have come this way.  The throttle smoothness and even power band make it a joy to ride.  I no longer feel as if I'm riding a wild bronco lol. Thank you again, I didn't think that a L-twin could behave this well.  Also, your customer service is the best.  I could always reach you by email or phone.  I will tell everyone I know about this fantastic addition.  Keep up the great work, guys! ”

    Dan Martinez May 01, 2017
  • “ I have a 2015 S1000RR and was extremely skeptical when I heard about BrenTuning and the power they got out of an ECU flash.  After speaking with the team at BrenTuning, all my hesitations were put to rest and I haven't stop winning first place trophies since! BELIEVE THE HYPE! ”

    Troy Gleason - California Jul 10, 2016
  • “ Bren and his team did an awesome job on my bmw s1000rr. Went from 179rwhp an 83 rwtq to 206 rwhp and 93rwtq. Customer service was great and I highly recommend them for any of y'all that want to make that power!! ”

    Paul Jackson - Texas Jul 10, 2016
  • “ Purchased the tune for my 2015 BMW S1000RR. Was skeptical at first and initially had a bunch of questions. Chris was very patient with me and answered them all. Had some problems after receiving my ecu back and Chris was very helpful in getting all my issues worked out. Bike runs fantastic. Definitely worth it. Thank you again guys for dealing with my questions and taking care of everything before and after the purchase. Fantastic customer service. ”

    Cody Hunsucker - Tennessee Jul 10, 2016
  • “ After doing some research it was obvious that Brentuning was the best option for tuning of my S1000RR. I wont go into details but after multiple overnighting of parts to me at no additional charge, I'm really impressed and satisfied with the end result and I haven't even tried out my race fuel tune yet! To top if off I received a random care package of goodies from Chris today. The customer service at Brentuning is probably the best I've received from any business I've dealt with. Their email response times are unreal as well, lol. Literally sometimes instantly, kinda weird. lol. I would recommend any and everyone to Brentuning for your S1000RR tuning solution. If anyone has any questions or are hesitant before purchasing, feel free to shoot me a message and I'll help / assist / give you a more detailed opinion on my experience as well. ”

    Trey Hull - Texas Jul 10, 2016
  • “ I have the Bren Tuning ECU flash on my 2015 BMW S1000RR and it is unbelievable how fast this bike is. This tune is the best thing I got for my bikes. I have also did the Bren Tune for my 2014 BMW S1000r for which it just made this bike really nice. Bren Tuning is the best. ”
