The EFI system is disappointing me

With that said, what you say probably makes sense....

Though I do believe that it is off and running.

Sorry but I am right about this one.
They calculate the density from the Ideal Gas Law(google it). Once they know the density they can calculate the mass by multiplying the density by the volume of the cylinder. Except they do not know the run time volume of the cylinder. So they have a correction factor, volumetric efficiency (ve). They multiply the displacement by the volumetric efficiency to obtain the run time volume. Multiply the corrected volume by the density and you have the mass of air. Divide the mass of air just calculated by the programmed AFR and you have the mass of fuel. Using the injector flow rate (gm/sec) you can calcluate the amount of time to keep the injector open to deliver the fuel you need.

Yeah, that was called in his previous train wreck. I come back often the replies he gets from everyone make me laugh.

The sorry part? Absolutely.

The answer should be pretty obvious to everyone by now.

If you actually know all of this, which I do from datalogging and writing custom tunes for modified Mustangs, why do you have a question about your bike? If it's not running right, take it to the dealership. There is obviously a problem, because the system is designed to modify the tune based on the conditions you're riding in. It's good to see that you're back on your meds though. Your posts are much more well thought out, except for the part where you answer yourself.
Threads have a mind of their own. No one can predict where they are going to go.
I guess its time to put you back on ignore.
Bang. Your dead. So stop responding.
