Product Description
**AFTER PURCHASE DO NOT SHIP YOUR ECU UNTIL WE CONTACT YOU**
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. Stage //M+ was developed to remove these restrictions and unlock your S1000RR’s full potential for racing use only.
WHAT’S INCLUDED IN STAGE //M+?
- Derestricted Throttle
- Derestricted Exhaust Valve
- Extended RPM Limiter
- Better Fueling
- Heat Management
HOW DO WE ACCOMPLISH THIS WITH //M+?
THROTTLE RESTRICTION – 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. To fix this we remove the throttle restrictions across the board. 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.
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. 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. Our mapping 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.
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 with zero negative 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. However, fuel can be trimmed for better result as it targets real time fuel corrections (think Dynojet PC5 Autotuner but better). Luckily this is the death of the piggyback fuel controller as the factory system 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. We program the S1000RR to target a better AFR (Air/Fuel Ratio) to make a little more power along with fixing drivability and idle.
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.
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 PROVEN
**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 separate 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.
**Testing performed with 93 octane pump gas. Usage of a lower octane will yield smaller power gains.**
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.
