Product Description




R18 Stage 1

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.


Perfect fueling, 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


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 FUELING FOR FULL-TIME CLOSED LOOP AND WILL TARGET FOR BEST FUELING 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 fueling? 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 Testing

The R18 isn’t know to be a powerhouse but there’s still power to be made. With our Stage 1 flash we were able to gain 6WHP and 4WTQ. We also were able to smooth the throttle with sharper response. All dyno runs performed back to back on our in-house DynoJet with the only difference being our Stage 1 flash.

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

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.

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


**Testing performed with 93 octane pump gas. Usage of a lower octane will yield smaller power gains.**



Affirm Financing



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 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.

  • “ Bike is running awesome and no out of the ordinary popping under load during downshifts at high rpm. My hats off to your team for making me feel like I have a personal tuner at my disposal. Really appreciate the quick turnaround to get me straight. I can definitely feel the extra power! ”

  • “ 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! ”

  • “ I have a 2015 S1000RR and was extremely skeptical when I heard about BT Moto 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! ”

  • “ 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!! ”

  • “ 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. ”

  • “ After doing some research it was obvious that BT Moto 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 BT Moto 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 BT Moto 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. ”
