Right right.
I need Speediuno to find immediate pulse width/duration.
I need it to find frequency. (Hmm RPMx2!? Two injections per rev.
u
Then multiply those two together to get a relative fuel demand number (quantity). Units don't really matter I don't think. (That number will be multiplied or divided again, depending on how far the step motor has to turn to increase or decrease fuel flow.
Then, if the increase and decrease resulting from incremental (step) turns of the needle valve is not linear, I can massage the air/fuel table.
(I'll have to experiment with fuel flows from various needle positions, running the fuel into a measuring container.) That should be fun.
If I can achieve full vapor, I should only need 1/5 the normal fuel flow of the engine.
I entend to make this the New Normal.
I want to say that vapor is a completely different animal. It does not burn hotter it burns cooler.
It not adhere to the so called stoichiometric "laws".
For example when a firefighters walks into a room of explosive gasoline vapor, his meter can read as low as 1.4 percent gasoline. There are no droplets present.
14.7 af ratio is only a helpful guide when droplets are present.
Car enthusiasts will have to get their head around this, but it's been around so long, it won't be easy.
Having said all that I'm really weak on the code and procedures to run this fuel flow stepper motor, but I'll keep hacking away at it, with any help like above (from dazq).
I think we've narrowed down the needed process quite a bit.
Thanks
BTW, people may wonder where I get this vapor information, it's out there, but not in one place. You can Google and check, and perhaps find out some new interesting information as well.
