BrenTuning Moto Flash ECU Custom Mapping - BMW R18 2020-2024

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.

The BMW R18 is the new motorcycle for those wanting a unique heritage cruiser, so we received two test bikes to dial in to put our twist on. Both in completely different weather climates to test in cold, hot and moderate weather. We made sure both bikes behaved the same and yielded the same results, without issues.

Stage 1 Benefits:

Perfect fuelling, all the time! The BMW R18 comes equipped with wideband oxygen sensors stock which fully target fuel at every throttle position. Once setup, the bike is running an “auto” tuner all the time! Never needing custom adjustments for aftermarket parts, etc. The bike will adjust itself for the new parts! With the options below we have a full-on unleashed and aural riding experience to enjoy this motorcycle to it’s best possible potential.

Here’s a list of everything we did with Stage 1:

• Full-Time Closed Loop (FTCL) Fueling Adjustments
• Removed RPM “Soft” Limiter
• Rough Idle Fix – Cold and Warm
• Increased Torque Limits
• Increased Throttle Limiter To 100%
• Sharper Throttle Response
• More Aggressive “Rock” Mode Rumble
• Increased Ignition Timing
• Fixed Bucking and Rev Hang
• Removed Top Speed Limiter

How we accomplish this with Stage 1

• RESTRICTIONS REMOVED. The OEM throttle model has “soft” and “hard” limits. The soft limits are where the R18 will start to close the throttle and limit torque by itself near the RPM limiter. We removed the soft limiter that comes in 600RPM before the factory RPM limiter.
• MODIFIED FUELLING FOR FULL-TIME CLOSED LOOP AND WILL TARGET FOR BEST FUELLING AND PERFORMANCE. Full-time closed loop tuning means your R18 can be programmed to always target a perfect AFR (air/fuel ratio). This new technology was just introduced by BMW and we utilize it to work at all times for you with Stage 1. Want to change parts on your bike and worried it may change your fuelling? Worry no more with Stage 1.
• MODIFIED IGNITION FOR ENHANCED PERFORMANCE. Stage 1 optimizes the ignition tables for performance and reliability. The R18 has multiple ignition tables. Depending on fuel quality, the bike will either choose more aggressive or less aggressive ignition map.
• IDLE AND STARTUP FIXES. Complaints of idle and startup issues are common. Stage 1 fixes these issues and ensures your bike starts up and idles right the first time, every time.
• INCREASED TORQUE LIMITS. Torque limits removed to give you more torque in the midrange and low end (see dyno graphs below).
• THROTTLE INCREASED TO 100%. Factory throttle limits are common these days. Our Stage 1 flash removes all throttle limiters and gives you the power your bike should have had right from the factory. The factory R18 throttle limiters are at 3500RPM.
• SHARPER THROTTLE RESPONSE. Throttle response sharpened to give you a more lively and responsive feel on the road.
• INCREASED “ROCK” MODE RUMBLE. Ready to Rock? “Rock” mode idle gives you slightly more rumble and shake, while “Roll” mode still retains its functions with no shake.
• INCREASED IGNITION TIMING. Ignition timing carefully increased to yield optimized power while still giving you OEM reliability and rideability.
• FIXED BUCKING AND REV HANG. Low RPM bucking and throttle lift “rev hang” have been reduced with Stage 1.
• REMOVED TOP SPEED LIMITER. Top speed limiter of 110MPH had been removed with Stage 1

Dyno Proven

RED = Factory tuning with 93 Pump Gas, 77WHP / 110WTQ
BLUE = Stage 1 with 93 Pump Gas, 83WHP / 114WTQ

The graph below shows partial throttle power. We gave the R18 more partial throttle power through the entire RPM range and were able to make the bike smoother and more predicable.

RED = Factory tuning with 93 Pump Gas
BLUE = Stage 1 with 93 Pump Gas

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.

Q & A's

Can the BT Moto handheld be used for diagnostic checks?
Some models will allow for DTC reading / clearing and maintenance light resets.

How does the BT Moto handheld tuning process work?
Easy, you purchase the handheld, we ship it to you. Use the BT Moto handheld tuner to copy your motorcycles stock file (motorcycle will still run fine after this) then email that to Motobull. BT Moto will then create a file from your stock mapping and we will email it back to you so can upload it to the handheld. Once uploaded you'll be able to flash your motorcycle with the BT Moto handheld tuner.

How do I put my motorcycle back to stock with the BT Moto handheld?
Go to "Work" -> "Writing" -> "Original" in the handheld and then it'll load the original factory stock file to your motorcycle.
