2005+ BMW K1200 Handheld Tuner

$895.00 $795.00

Transforming your K series from the comfort of your own home!


Product Description

Flash in / flash out Mapping for all models.

50+ ECU Map corrections to:

Ignition Timing per every fuel, conversion to lambda, cat off changes, full throttle limiters, engine braking in all modes, cold and warm start, driveability issues (removal of known flat spots), speed and rev limit adjusted for max power, lambda limiters, throttle valve, adaptation to race fuels.

We spent a ton of time removing the midrange and bad sluggish throttle response, along with the jerking and bucking throughout the power range.  The bike drives like a completely different monster after mapping!

Advantages over current tune offerings:

Actual power tuning (not just wide open throttle AFR 2-3HP gains)

Flash at home option, Easy install, Easy removal, and diagnostic tool all in one, and resale

Can be used with or without piggybacks (RB, PC5, Bazazz)

Pre-mapped for popular exhaust options

Modifications are made to:

Fueling – Air mass, idle, part/full throttle and Lambda correction maps

Ignition – Base, limiter, optimum ignition, optimum angle, correction maps

Throttle – Remove 80% WOT limiter, perfect throttle twist adjustment for all desired load angles for maximum response control and power under the curve, rev/speed limit

Torque – Adjust torque model to align with new power of bike/limiter removal

Quickshifter – Shorter up and downshift dead times for maximum driveability and acceleration

Bike Adaptation – Ignition/fuel calculation for maximum performance and response for upgraded fuel qualities.

Quantitative differences:

– Drastically improved throttle / engine response at all throttle angles with a great highway cruise range.

– Drastically decreased delay times in short shifter response on both up and downshift.

– Removed bottom end dead spot in low RPM range.

– Heavy increase in top end power via limiter removal. Especially noticeable between gears.

– Increased power 8% over entire power curve on premium pump fuel.

– Compatible with our DIY Fueling (add Bazazz / PC5 with our tuning notes).

– Smoother powerband and increased cruise range fuel economy.

– Full restriction removal for enjoyable and predictable experience.

– Diagnostic invisibility.

– Best bang for your buck upgrade.

  • “ 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 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! ”

  • “ 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 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. ”

  • “ 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. ”
