Woolich Racing Releases Self-Tuning Option For 2020 BMW S1000RR
Woolich Racing Releases Self-Tuning Option For 2020 BMW S1000RR 30.10.2020

We review the Woolich Racing release of their self-tuning option for the 2020 BMW S1000RR and weigh the pros and cons for you


Our thoughts after 10 years with BMW’s on the Woolich Racing Self-Tune / Customer Tune $972 plus $100 for each additional bin file


Assuming you know what you’re doing with BMW ECU’s, Woolich Racing’s new software will allow you to tune your S1000RR yourself, make constant adjustments at home or the track, bring it to your local dyno guy and see improvements from tuning. Before you start jumping in the air with excitement for a new do-it-yourself tuning project, let’s break down the reality of this endeavor.



Tuning it yourself is pointless as the 2020 S1000RR, when setup correctly, has “closed-loop” fueling and closed loop ignition timing (no custom tuning needed).  The bikes will hit a specified lambda target, correcting 35% in either direction, and read knock learning from the dual knock sensor strategy. This means it will automatically pick from 4 different levels of timing maps to suit the fuel in the bike.  This takes the guess work out of custom tuning.

90% of the fueling maps listed in the Woolich Racing’s editor aren’t needed on these bikes due to the wideband fueling strategy.


Bench tuning only. You are going to remove the lambda closed loop system that was engineered by BMW over years with million in R&D and replace it with a 2x, 32×32 fuel map that you’ll have pull the ECU out each time and bench over and over to make changes?  A proper tune would be endless hours in this manner, that’s if your tuner had a 4 channel wideband and a load based dyno.  Most don’t have this equipment available to them, much less know what it is in the first place or why you would use it.


No back to stock updates, only European software (as of now).  No fix for dealership updates (6 software updates per month on average)

Forcing a reflash European version into a bike is VERY BAD. The dealership will pick up on this software version in the “ISTA” system while the bike shows as EU features are enabled (for an EU bike this isn’t an issue). That’s when they question the warranty of your bike immediately.  Let’s also keep in mind that since this software is bench flash only for any changes (dyno fueling changes, different fuels, elevations changes for open loop system), the flash counter will be through the roof, another huge red flag. 

There’s a guy on eBay that has been force flashing European files on 2019 for $2000, the mileage could appear “true mileage unknown”.  This is when the ECU and cluster have conflicting mileage data.  This turns the mileage red and the bike then looks stolen or cluster swapped to BMW.  Not really the best practice when it can be done correctly, especially on an expensive, new, BMW motorcycle.  The rev-limiter (RPM) raise done incorrectly will trigger overspeed and warranty failure as well.


Missing many BMW key features the software itself is extremely basic and cannot handle most of the modern innovations BMW has put into the 2020 S1000RR that make it so great. Eliminating the factory closed loop wideband system is a step backward for tuning, not forward.  The closed loop system can be set to target a specified lambda and hit it every time and works for every throttle position and RPM.  This is because it’s always adjusting (when setup correctly).  You don’t even have to change mapping for fuels, ignition will automatically adjust, flex fuel is an option with the closed loop system.  Woolich has you delete that system in favor of an open loop system. You’ll have to make constant changes to stay competitive depending on fuel, elevation and other factors.  You may need to have upwards of 10 maps ready to flash into the bike depending on what you’re doing. Then go and make test passes, log them and see them on the computer.  That’s when you’ll have to adjust the map and reflash the ECU.  This means you’ll have to pull out the ECU to do this.  To us it seems much easier to set a target and let the bike do the work for you.

The fuel maps:  They give you the mass air maps that are disabled on some ROMS, and only 2 of the 8 lambda maps.  They are missing the full throttle trim maps.  No logging or wideband Zeitronix cable.  Deceleration fueling and factory O2’s off. Cold start off and idle speed don’t fix the cold start issue with the 2020.  The cold start issue is a combination of fueling, idle maps and warming strategies. None of which are available in the Woolich software.  All of this is already fixed for you with a closed loop developed OTS (off the shelf) tune.  In this self-tune model you have to do it yourself manually and it will change will elevation, weather, or location. The point of the 2020 was to get rid of road side tuning or track day adjustments, and now you add it back with this product.

The ignition maps:  They are labeled incorrectly and the bike switches between all of these while riding based off knock activity.  BMW does auto-tune ignition, so there is no power made in these tables or adding to it without changing the strategy.

The rev limiter maps: You get a one byte change.  Woolich can’t adjust the rev or TPS maps for the rev limiter. Also the map they use is for protection of the rev-limiter is missing and cannot be changed. This means warranty void. This is disabled in our mapping allowing you to extend rev freely without triggering the throttle or overspeed fault.

The ETV maps:  Throttle limiting isn’t a huge deal on these, as they are 100% open Euro stock.  The difference here is you can nudge it up or down.  The problem we see here is the protection maps (that need to be modified in the same manner) are missing so if the ECU doesn’t see a mirror of it, it will go into limp mode with changes to these map. Adjust these with caution, they are missing a lot.



This kit is $972 for someone to get access to a stock European bin file.  This is pricey for basic features the bike doesn’t need (fuel and timing changes), and you are force flashing the bike to a different software version. This will be detected at the dealer level in the US. The Euro files have different markings for the dashboard and closed loop fueling.  Couple that with the missing and incomplete “structure” of the above maps that don’t fully understand how a BMW truly treats its engine management.  The maps are copied out of basic editors like Dimsport and Alientech, that provide very basic tables for beginner tuners, and most are labeled incorrectly.

Turning a sophisticated closed-loop wideband motorcycle into an open-loop bike is a huge step backwards.  The beauty of the BMW is its car-like sophisticated self-tune sensors and ECU stratagies.  Woolich is not BMW centric and does not understand the inner workings of the ECU or how they make power with a S1000RR.  They have given you a way to figure that out for yourself when it doesn’t perform as expected. Woolich offers you a way to remove the factory fueling model and make it an open-loop.  You get rid of what makes the BMW is so awesome and replace it with a Zeitronix aftermarket product.  The S1000RR has dual wideband and dual narrowband sensors in the exhaust. Woolich gives you one wideband you have to weld a bung into to sniff all four cylinders.  It’s not even close to as accurate as the factory reading.  You can never make an single aftermarket sensor that works as well or better than a two factory widebands and an ecu that’s built around that strategy.

While we think it’s a great thing for most shops to make a bit of money, people will get frustrated with it when trying to use it in this capacity and return to researched and developed tuning products.

In conclusion, most use this software to get rid of ETV or decel cutoffs, deletions on a Japanese bike that have them.  However, this bike doesn’t have any of that.   A euro bin file is derestricted stock. The rest of the ability with using the self-tune software is dialing in your own AFR with a log box and autotune, but this bike doesn’t need that.  Same goes for ignition. 

The people that will want a self-tune want that extra 1%, that extra lean AFR, or an aggressive timing curve to make that 2hp for the race, which puts things at risk. Our other models like Aprilia, we find offering self-tuning frustrates 99% of users and they convert to us as it’s a turn-key solution.  Doing it yourself sounds fun until you have no support, directions, lack of properly defined maps, and a half defined map where the author has no true understanding of the ECU or motorcycle itself. 

The development of our product is 10 years of experience with full factory info of these bikes to extract race-ready performance, and it’s not in ETV, fuel, or ignition maps.  We use 2,000 unique maps and our own motorcycle, racing environment, and dynometers to dial in what works on a bike that is very tricky to make power.  What you pay for with us, for less money, is a fully developed tuning product with more features and functional ability like full-time closed-loop, an ability to read and write through the diag port or put it back to stock when going to the dealer. without worry of blowing an engine or scaring your ECU with bad info. It’s already done for you! 

What you pay for is experience with people that eat, sleep and breathe BMW.  Datalogging of 100+ hours of an engine with true factory developer tools and testing to extract more power.

  • “ 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! ”

    Andy Young - Maryland Aug 28, 2018
  • “ 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! ”

  • “ 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. ”

    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. ”
