2022 Bren Tune Observations

9K views 44 replies 16 participants last post by  RedCard 
For those who don't know, I've had a 2014 GTL and a 2018 GT before the 2022 B. I'm trying to think back, I honestly can't remember if I tuned the 2014. When I first test rode the 2018, I instantly felt something was amiss with the power. We all came to learn about the infamous throttle lag during those years. Dark times were they. The Bren Tune corrected the misgivings of the 2018 for sure, and that engine needed it.
I rode an early one massive hole circa 2k rpm, improved on the later bikes post 2016, 2022 LCD dash bikes get major power and torque changes in line with need to meet euro 5 emission regs - two more cat sensors and they wound up the ignition curve with improved knock detection = more torque and slightly more top end grunt 1000 rpm lower (with same cyl head and cams)

so an adaption bodge up (stretching the manu built in adjustments) and fixing them closer to the edge, would pep the bike up a bit. But this is not and has never been remapping - and this can only go as far as the manu adaption area took the bike. If emission regs / other needed tweaks need to go futher fixing the disaster map the manus build, then this type of change isn't the right way forward.... woolich racing have taken on how to get at BMW ECUs and the madness of their engine maps in the last year, so the world could be about to provide the correct way to do it for the K1600 if we ask them

its not me, its well known world renowned bods that win races - but they only started getting at BMWs recently - they had ignored probably the biggest market and revenuse stream avaiable to them - which would suggest they are more in to playing with bikes than making money

the knock detection changes of the new 2022 k1600 and the fact they can now get far better emissions control, ecomony and much more grunt at lower revs by writing the correct ignition curve makes you wonder what the **** BMW have been doing for 11 yeas !!!
 
manufacturers are supposed to adhere to emission regs
unless it's a german car and then the rules don't apply for 5 years / and or EPA go looking
its a demo bike and they put on a special map
or its a german press release bike and they put on a special map + a two week holiday in a nice hotel if the journalist agrees to say its base price in all reviews - knowing full well they where riding one with 10k worth of options
 
I was looking last night at parts and I can't find a knock sensor on the pre 2022 K1600.... if true that would be shocking - nearly all models had one for many years and you basically need one - changes to knock detection / and ignition curve are what got more grunt at lower revs on the new model

these all use the same "ping sensor"
 
That's insane - so they put one on virtually every other bike then built a flagship and saved 7pence by leaving out a vital bit of kit - which would allow the engine to cope with odd conditions, odd fuel and odd riding

wow so a bit of programming by a gown up and probably plugging in a sensor and we can all get 2022 mapping level of emissions and performance
 
Interesting that you have an opinion on every aspect of engineering of motorcycle engines.
The original design of the K1600 was done by Ricardo engineering based on the 4 cylinder engine that they conceptuallly designed years earlier. The K1600 was a big, lazy and dumb engine with little or no need to have knock sensors employed to manage the engine. If you have evidence to prove that a wrong statement, please bring it forward.
Ricardo re did the K1200 engine as it was an utter disaster as built by BMW, and in creating the K1300 engine they used the knock sensor and the bike makes considerably more go when moved to super unleaded fuel as recco in the handbook vs std unleaded fuels

the very fact they have now added a knock sensor on the k1600 - getting more power, better fuel consumption and considerably lower emission - proves it ALWAYS needed one

People shouldn't automatically have a pop - they should read, learn and grow - not hurl invalid abuse believing the world as is as as good as it should be and things are done for the right reasons, they left it off coz the accounts said the idiots will still buy it, it'll save $3 a bike, and help them fail faster which should increase sales ....
