there is a lot of info in this thread - https://www.s1000rrforum.com/forum/exhaust-fuel-delivery/90202-bmw-bosch-ecu-how-works-what-you-need-know.html

reseting the adaption tables with the GS911(or other tool, or at the dealers) just speeds up the re-learning process for the ECU. putting miles on the bike after a change will result in the same, but will take longer(200-500 miles have been mentioned). I am by no means a tuner or expert of any nature. I do know that out of the box these bikes run really lean(to conform to emissions standards), they have fueling targets in the maps to achieve this. The ECU is supposed to be a 'learning' ECU, so when you make a change it should adapt to that change, BUT it is always going to try to achieve the fueling targets set in the ECU map. So, do you need a PCV? Supposedly not, but you could make the fueling better(though I would not expect to see huge increases in HP).

You can reset the adaptation tables with a GS911. This is not an ECU re-tune, or the BMW ECU unlock code(which I understand voids our warranty).

Thing that makes me super jealous of my friend who bought a new MT10.... he can take his seat off using his key :P

thats exactly what i want but to reset the adaptations is to reset the ECU correct? do you need the unlock code from BMW to do this? because that will be my only dilema. IF you can just have the ecu reset and thats it i.e no power commander or anything and it fuels fine and the throttle is all good then ill be one happy chappy. they were just saying to me that it needs to be tuned as in the ECU needs to be re-mapped and tuned etc and for that i need the unlock code from BMW at a cost of 1k

Feel free to add/edit.
