Hello from Spain!

Hello everybody! I'm glad to be on this community and hope to contribute on this project.




I'm working on a small 2T(two stroke) engine and I have tried few injector (chinese ones) and the curve of pulse width vs flow ml/min tends to not be a linear one.
I have used the frankesco board and Keihin and still dooing the same.

On the next images there are three graphs of different injectors where in the X axis we have the PW and in the Y axis we have the flow ml/min.

However , I have seen that Ms3 have and option in tuner studio called non-linear small pulsewidths like in the next picture

I don't know if Rusefi has that feature,If not I would like to implement some injector tables to improve the non-linear behavior of the injectors. So I will need your advices and help to do it .

Also I have seen some ticket on source forge https://sourceforge.net/p/rusefi/tickets/269/.

rusEfi does not have such injector tables, someone would have to implement those if desired.

I believe your tuned fuel table typically compensates for this kind of issue as well as the table compensates for many other issues. I suspect you will not see much of a performance difference on a table driver design. If we get around to doing model based calculations instead of table based calculations this injector linearization would be quite helpful.

Are those tables the pulse width vs. flow rate, or the pulse width vs. the fuel QUANTITY per pulse? Because to me, they look like quantity per pulse. I don't know of any injectors that flow fuel more quickly if you open them for longer.
