after disconnecting the battery, connect the + - battery terminals with each other, And turn on the key.
Is it the same effect? - Is the idea good?
Why didn't I think of that? Yes. Rather, remove the posi and all wires off the (+) side totally off the battery. You can keep the ground on the battery and frame... it does nothing as you can see. Ground the posi cable and hold it there, then cycle the key a few times(6).
Back to O2 - I wonder - Working O2 (theoretically) badly affects the map of the injector opening in the ECU.
Kind of yes, kind of no. If say it rides fine for a few days and then acts up, were you riding it mildly for those few days? Or were you hitting those short bursts of high rpm [like me every time you're on the bike], and then it started to act up?
These changes are stored in the ECU
The way I understand it is; the processing is almost at the speed of light, and that is why this one hard part called an integrated chip (IC) can dump the capacitors thousands of times a second, can detect the most minute slowing down in speed of the front wheel, where the ignition is retarded, the sub is closing, and the injector leans out, the wheel comes down and you probably didn't notice it. The processing works that quick. So when the IC grounds, it empties the capacitors, is waiting for the next rpm speed [making E] at the crank sensor, that pulse up the wire is the next electrical value the processor can read. So the change is thousands of times a second in between those spark advances, and injector demands.
Because on the second, third day, it is already working badly since the start of the cold engine
That's the clinker about this one:
1. Can't be the hard parts or they'd code.
2. Can't be the plugs or element.
3. Can't be the ECU.
4. Can't be the mufflers/cat... because it takes awhile for it to appear so no codes to point to, no plugs, pipes, etc., see list above.
Suction ECU (cold) not responding to O2. How will I disconnect O2 then, will it not start using the wrong map, previously falsified by the O2 sensor? Only without O2?
I believe the 02 is sending input upon key turned on. Get it? All parameters are cold, so of course it is going run rich at startup. The 02 reads the heat (chemical reaction) and shuts off the rich/choke as the temps change.
The gray 02 connector is near the #4 exhaust header. You might have room to reach around the lower fairing and see it from there at the front? That will tell you how much side cover to take off, if you can't disconnect from there at the front. Look down on the right side of the lower headers enter the collector. You cand see the 02 screwed in that collector area. follow the harness up or look at the front of the fairing, you'll see the intersect. Disconnect and do not let the wire drop on the pipe.
The bike starts with a backup map. It's not necessarily a wrong map, it's more a 'redundant' map, a failsafe, a limp map, a backup map, a check engine light map, a 'Huston we have a problem' map. Well, we shall know soon enough if it falsifies the input to the ECU. Without the 02, it's called open loop. With an 02 system, it's closed loop.
Do you like to rev up the bike hard when you ride it? Well over a ton when no one is looking? Go off to an abandon road, do burnouts? Plan old, beat shit out of the bike like I do? And then the hole begins? I've been there, done that with my 02 emission 2017 14. Are we talking the same wrist action?
