Introducing our inaugural flash for the 2020+ BMW S1000RR! Utilizing our decade of experience and research into the BMW S1000RR has helped us A LOT to develop the 2020 RR Stage “//M+” Flash over last year utilizing European pre-production items.

 

What Is Stage //M+?

US and European model S1000RR’s have been restricted from the factory, with the US models having some of the worst restrictions we have ever seen on a BMW liter bike short of the 2017+ BMW K1600. These restrictions are due to many factors; insurance, safety and noise regulations (US models) as well as EURO4 regulations (Euro models). Stage //M+ was developed to remove these restrictions and unlock your S1000RR’s full potential for racing use only.

 

What’s Being Restricted?

There are quite a few software and hardware restrictions on the 2020 S1000RR and some of the restrictions work in conjunction with one another.

– Throttle Restriction

First and foremost there are HEAVY throttle restriction with the worst offender being the US model. Take a look at the photo below. You can see a comparison to the US and NON-US throttle table. Reading the top of the graph from left to right is RPM. Reading the left side of the graph from top to bottom is the gear. You can see “1.00” and “2.00” etc. “1.00” means gear number “1”. This graph reads the US and NON-US model first through sixth gear restrictions. The values inside represent OEM throttle opening percentage. Let’s look at the US model, 2.00 (second gear), first value to the left — That’s 40% throttle!! This is why we see a lot of complaints from US S1000RR owners about the bike “feeling like a 600” in the mid-range for second, third and fourth gear. Second gear will feel like a 600, third gear feels like a 750, and fourth is more like a Ducati 959!

 

– Exhaust Valve

The exhaust valve is a double edged sword. It does good by making back pressure when needed but also hinders the 2020+ S1000RR from making the most power possible at mid to upper RPM. Why would they do this? Noise regulations. The valve closed makes the bike a lot more quiet than if it were open. Even slip-on exhaust sounds almost the same as stock due to this valve closing so much. The US vs NON-US models use completely different and more aggressive exhaust valve tables for the upper and lower exhaust valves, but both bikes are heavily restricted in the grand scheme of things. Opening these valves for racing use allows for some horsepower as they are both gear and RPM dependent just like the butterfly valves for the throttle. Lower gears will reduce sound and power by 3-5HP by only opening the valve less then 100% even in high RPM’s.

See the graph below.  We extracted this table from the US model software and is unmodified.  From left to right signifies RPM and the 0-6 on the left from top to bottom represents neutral to 6th gear.  The values inside the table represent how far open the OEM software allows the exhaust valve to open.  You can see there’s only a 45% opening at 10,000 RPM in second gear.  Neutral being the worst.  You won’t win any rev competitions with a 30% exhaust valve opening!

– RPM Limiter

The stock RPM limiter is set to 14,500 RPM. As you notice with this limiter most bikes will crash into the rev limiter while still gaining power. We have been testing 14,800 and 15,000 for a while with power still climbing and no side effects.

– Fueling

The 2020 BMW S1000RR fueling is set rich for exhaust gas temperature purposes than it needs to be from the factory. It is also set artificially lean at idle, cruise and warm up which results in stalling and cold/hot start issues. The new S1000RR is factory equipped with 5-wire widebands (new for the S1000RR and any motorcycle we know of!) and is very precise on targeting a specific AFR (Air/Fuel Ratio) through a closed loop corrective system from idle to redline. Being factory rich also helps it cool the turtleshell exhaust system and meet street standards. However, fuel can be trimmed for better result as it targets real time fuel corrections (think Dynojet PC5 Autotuner but better). Luckily is the death of the piggyback fuel controller as the factory system and is 200 times better and more effective per gear, per EGT (Exhaust Gas Temperature), and per throttle position than any other aftermarket oxygen sensor deleted alpha-N piggyback system (Rapidbike, PC5, Bazazz) on the market. This also means in theory you can run race fuels, light ethanol mixes, light nitrous mixes as well with one tune — we will test this in the future.

– Heat Management

Let’s face it, this bike rides insanely hot! Due to the new exhaust system and idle/cruise air fuel mixtures the bike has it is a recipe to being constantly in the 215+F range and burning your legs while you ride, making it uncomfortable anywhere you’re not going 50+MPH. We have solved this issue by adding our low fan temp modification to this flash level as a standard baseline feature along with different cruise mapping which has curbed temps extensively.

 

What Do We Do To Fix These Issues?

– Throttle Restriction

We remove the throttle restrictions across the board. We do not force load a European file/Eeprom as this has its own set of flaws and could force your bike to have an identity crisis or get you in trouble with BMW. This restriction is software based only and doesn’t require anything but a software modification on our side to remedy. As soon as you get your ECU back to your motorcycle, it will feel like a night and day difference from stock. In some gears the bike is missing 50HP and 40TQ! This is how a BMW S1000RR should feel. If you’ve ever ridden a 2020 S1000RR you know how fast and furious 6th gear feels compared to 2nd. Imagine that feeling in 2nd at low speeds. It’s wild.

See the photo below we took of a US model bike. The red lines represent the OEM throttle restriction and the blue lines represent our Stage //M+ flash on the same motorcycle. The result is a huge gain in torque and horsepower in the mid-range. This is where the most complaints of the bike are which is now fixed. Testing done back to back on our dynojet.

– Exhaust Valve

We still utilize the stock exhaust valve to give you maximum power but also open it up when you need to make peak power gains and the sound you want.

– RPM Limiter

We moved the limiter from the stock 14,500RPM to 14,800RPM. We have tested this extensively on our own in-house S1000RR and found that it’s still making power to 14,800RPM without any negative side effects to the engine. This is optional when ordering.

– Fueling

We program the S1000RR to target a better AFR (Air/Fuel Ratio) to make a little more power along with fixing drivability and idle.

– Diagnostically Invisible

This flash will not show up on current BMW diagnostic tools. This is not just a Euro RR file. A Euro file simply has 2-4 restrictions removed but still has issues with fueling, cooling, exhaust valve and being a visible modification to a service location by throwing an incompatible file mismatch at the dealer level among incorrect VIN# and other related issues that you don’t want to get into.

Benefits:

– 40TQ / 50HP gain in lower RPM’s in certain gears (see graphs below)
-2-4hp from exhaust valve management
-Cooler riding temps
-Cold start, hot start stalling issue solved. Idle is smooth and consistent
-Improved throttle response in all gears
-Longer Powerband
-Better exhaust note (as bike is silent stock due to exhaust valve)

 

Dyno Graphs

**Below are some graphical testing of different gears and scenarios we performed on our 2020 BMW S1000RR**

Flashed vs Stock

The graph below represents a third gear pull, back to back.  Our //M+ Flash vs the stock baseline.  We did these pulls in third gear to show just how crazy these limitations are in the lower gears, second through fourth gear being the worst.  The blue line is 100% stock.  The red line is our //M+ Flash that includes a higher redline, derestricted ECU and a Sprint P08 air filter.  You can see there is a gain up top but the biggest gain is the mid and low range.  This difference make your bike feel like an animal.

 

Below is a HORSEPOWER only representation of our 100% stock 2020 BMW S1000RR.  The seperate colors represent different gears we overlayed on top of one another to show the restriction by gear.

Red = Second Gear
Purple = Third Gear
Green = Fourth Gear
Yellow = Fifth Gear

You can see how restricted the bike is in the lower gears but starts to open up in fifth and sixth gear.  Our flash eliminates these restrictions.

 

Below is the exact same test, but showing torque differences in 2nd-3rd-4th-5th gear on a stock USA 2020 BMW S1000RR bike.  The colors represented are the same as the above graph.

 

Below is a 2nd gear vs 6th gear pull (LOOK AT THE DIFFERENCE IN LIMITERS!) on a stock USA 2020 BMW S1000RR bike.

 

Below is a 3rd gear with and without our exhaust valve management changes on a stock USA 2020 BMW S1000RR bike. We chose 3rd gear as the bike doesn’t restrict the sound as much in higher gears but it does in the lower gears. It does from 1st-4th.  The blue line represents our //M+ flash without restriction and the red line represents stock.

 

Below is another test, why European files don’t work as well as US files in 6th gear. Here is a back to back test of the low end differences of a 6th gear throttle management file for EURO VS. USA. The USA file regularly makes a little more low and midrange.  Even Euro S1000RR’s need a derestriction.  Though the restrictions on the Euro models are nearly as bad in the lower gears, the //M+  flash can still help make power.

 

Look below. To conclude our testing, a Sprint Air filter was installed in our 2020 BMW S1000RR and tested back to back. Back to back on the dyno in very hot conditions.  The red line represents the Sprint P08 filter test and the blue line represents the stock air filter.  No software changes were made during these dyno pulls. We strongly recommend the Sprint Filter with the //M+ flash.

 

 

SIMULATED ACCELERATION TESTING

This test was performed on our Mustang Dyno.  Because Mustang Dyno’s simulate load and wind resistance, we can get a pretty good idea of how the bike will perform, while in a controlled environment without breaking any speed laws.  All tests were performed back to back with same starting gear, dyno settings and load to ensure accuracy.  Do not take these numbers as an absolute for your own acceleration times.  There are innumerable variables that may cause your times to be faster or slower than what we tested.  This test is purely to display the difference between stock and flashed to show improvements.

The first test is simulated 60-130mph WITH the stock restrictions.  You can see the time is takes to go from 60-130mph is 4.36 seconds.

 

With our //M+ flash removing the restrictions, you can see a HUGE improvement from 60-130mph.  The S1000RR goes from 4.36 seconds to 3.82 seconds!!  That’s almost half a second improvement from just removing restrictions!

 

We went a step further and performed another test at a lower RPM to really show how heavy the restrictions are.  This test is 40-120mph.  Starting at a lower RPM really let’s us see how bad the low and mid-range is with the stock restrictions.  This test is WITHOUT our flash.  We managed to get a 5.42 second 40-120mph.

 

WITH our //M+ flash the 40-120mph time went from 5.42 to 4.32 seconds!!  That’s almost a full second difference!  It’s clear our //M+ flash yields HUGE improvements over the stock (restricted) software.

  • “ 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. ”
