Not sure what the point about barometric pressure is
It's what the bike is handcuffed to in the math of it. This is what happens when the 02's [analog] fails. What happens next is the backup as in [one] digital number being sent in. Digital means: 1 number; one ohm resistance; one frequency. So what you are doing is toggling on an analog signal or toggling a single signal. You turn off the 02, what happens next is the 760mmHg is the digital move you made. The analog has the 100 to 900 range in the IAP.
Your 02 is our IAP. We have a matching sensor that sits under the seat. This is the same 100~900 range as the IAP. So it has the same exact range. Same as saying I'm going to run lean with less pressure against tail sensor: moving up a mountain. It's the same as saying, I'm feeling some fat, rich wet, we must be climbing with less air, let me ping some shit I'm getting cold too. We going ice racing? It's sort of redundant are the two? So when both sensors fail to be plugged in say? Say the bike still runs, has a 'backup' in digital is the 1ATMO.
So when mother teapot pours out the abstract saying, DFI for digital fuel injection, all she is saying is, hey look at my backup. I'm just saying fancy words for what and how the system works like. They can't get away from 3ti's: the on/off. The 1's and 0's to make it all work is all there is left is how little 14.7 is sea level and all the rest is a ping up or down in elevation/pressure/temp = 3ti's it gets complicated but easy at the same time.
but the o2 sensor only operates at at certain throttle positions in certain gears
I think you have part of it right. It is my understanding that if we ignore the trans and look at the engine, it is load canceling? The 02 cannot keep up with, nor is designed for WOT loads. It is under a light load that it kicks back in. Take a PAIR hose off and listen to it come on and off you rap the throttle up and that means under load will it hit the rev limiter: be careful. It is saying the 02 is so slow how could it keep up with the rpm if its bandwidth is slow to begin with. An 02 running slow is just for idle and cruise is more no to light load is happening: in the rpm of it.
this is also documented on the power commander website (eg the need for the o2 optimiser)as the pcv can't tune these positions due to the o2 sensor counteracting the inputs..
Correct. It's going to memorize the input you grid the cells in. If not, you have a resistance input problem? How could it if its programmed to send in the analog under 1 volt. If you are saying the 02 runs between 0.1v to 5.0v, and I am saying an 02 runs under 1.0 volts, we have a frequency problem. See how it does not matter? It just resets the input numbers from under 1v to now the analog is 0.1v to 5v it still says analog [many] and that says correct input. But if we say the input is now 0.0 to 4.1v, see the 10th of a volt lost and the remaining 10th's out of range of the 5v needed? The ECU now goes digital is the 1 atm number. Kind of see the either/or of it?
I don't intend for this thread to turn into a flaming session as im only passing on what I know/understand and what im doing with my bike..
This is how the thread should have started out to be. Solid input, bugs, solid input. No way am I flaming is passing on what I know/understand.
I'm all ears. And you're making me cry I almost had a reach around. But if you say is right you have no access to certain parts, I'm going after the bike on the outside. I'm going to bung my bike and find some smoothing on this bike with my AFR meter like I did with the 14. You are the senior 'bug master,' cj. It would take me way too long [in years] to get a handle on the inside. You've got some road on you so continue on.
