BrenTuning Moto Flash ECU Custom Mapping - BMW M1000RR 2021-2022

BMW Handheld Tuner with Custom Mapping

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

US and European model M1000RR’s have been restricted from the factory, with the US models having worse restrictions than it’s European counterpart. Stage //M+ was developed to remove these restrictions and unlock your M1000RR’s full potential.

WHAT’S INCLUDED IN STAGE //M+

• Derestricted Throttle
• Derestricted Exhaust Valve
• RPM Limiter Raised
• Better Fuelling
• Heat Management
• Warm Up Changes

HOW DO WE ACCOMPLISH THIS WITH //M+

THROTTLE RESTRICTION – Giving you the ability to to utilize 100% of the throttle is paramount in track situations where you need all the power you can get on demand. The factory file has “dead spots” that may cause the M1000RR to behave in an unpredictable manner when corner exiting. This also means any kind of straight line acceleration also suffers. We remove these factory restrictions to ensure a smooth and predicable throttle, all the way to redline.

EXHAUST VALVE – The exhaust valve is a double edged sword. It does good by making back pressure when needed but also hinders the 2021+ M1000RR 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. 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.

RPM LIMITER – The stock RPM limiter is set to 15,100 RPM. As you notice with this limiter most bikes will crash into the rev limiter while still gaining power. We have been testing 15,300 RPM with zero negative side effects. The M1000RR’s factory configuration actually varies in RPM from gear to gear, something we haven’t seen in BMW till now, but have seen in Ducati for quite some time. We set the RPM limiter for 15,300 RPM in all gears.

FUELLING – The 2021 BMW M1000RR 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 M1000RR is factory equipped with 5-wire widebands (just like the 2020+ S1000RR) 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. We program the M1000RR 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:

• 10HP gain in top end RPM
• 2-4hp from exhaust valve management
• Cooler riding temps
• Warm up stalling issue resolved
• Improved throttle response in all gears
• Longer Powerband
• Better exhaust note (as bike is silent stock due to exhaust valve)

Dyno proven

100% stock M1000RR on the dyno with our ///M+ flash. This bike has the ability to make 200whp completely stock with just our flash and no other mods. You can also see our attention to detail on the AFR (air/fuel ratio).

STOCK VS FLASHED, SECOND GEAR
This is a pretty drastic contrast. Doesn’t even look like the same bike! The throttle restrictions on the US spec M1000RR rob a significant amount of power in almost every gear. We pictured second gear because it has the worst restrictions. You’re seeing it right, that’s a gain of over 50whp from stock to flashed at almost 13,500 RPM.

M1000RR WARM UP, BEFORE AND AFTER //M+ FLASH

The M1000RR seems to suffer the same warm up issues as the 2020+ BMW S1000RR. On the stock tuning you can hear the bike struggling to stay on. It lean pops and sputters until it shuts itself off. Luckily we have a fix for it! Our //M+ for the M1000RR not only fixes the warm up and idle issue. You can hear the bike has a steady and healthy idle with no popping or sputtering.

What is a Handheld Tuner and what are the benefits of having one?

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 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 bike’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.
