thank you for the answer which helped me identify the condition of the O2 sensor.
1. It is Ok since it follows the typical plot. Furthermore I have asked a friend with an older model (single spark) and plotted his O2 sensor behavior which is almost similar.
2. About the reset of the BMS-II, which I have done a couple of times I have observed the following:
a. Motorbike is cold (environmental temperature). Did the reset and then started the moto up to the moment the fan starts. It takes about 10-15 minutes for the fan to start. Idle fluctuates up to the moment it stabilizes and everything seems OK for the next couple of days.
b. Motorbike is Hot (after having her driven/returned from the job)-(engine temperature about 90-95 degrees Celsius).Did the reset and then started the moto up to the moment the fan starts. It takes about 3-4 minutes for the fan to start. Idle stabilizes at 1500 rpm and moto seems to work better for the next couple of days, than following the previous “cold reset” procedure.
c. Motorbike is in operation. I have tried to reset the BMS-II and it does not allow me “ No response from the controller” is the message I am getting in the GS911 program
3. I do not know how the GS911 is resetting the BMS-II is working, but is it possible not o clear the data, or clear partially the memory of the BMS-II. I cannot understand why at the very beginning everything is working fine and after having driven the motorbike for a couple of days, she starts behave the same.
4. After having reset the BMS-II do I have to switch off and on the motorbike switch in order to re-boot the BMS-II?
5. I have been said by another person in another forum that he heard that it was necessary to have the BMS-II reset up to nine (9) times to finally learn the new values.
6. Finally another observation I have made about the idle rpm is that if the motorbike is left under the sun (temperature about 25-28 degrees Celsius) the idle goes up to 3000 rpm dropping to 2000 rpm (500 rpm higher than the normal). If I switch off the motorbike and then on sometimes it returns to 1500 rpm and sometimes remains to 200rpm.
7. I did logging of the values and I do have a *.csv file. Is there someone who has a similar logging?
It is strange unless the BMS-II has a corrupted program (firmware). This software has been updated by BMW 6 months ago to the version 210E.
Any comments/advices to the above may be appreciated.
