Could I run bleed off valves on a mechanical pump with rusefi?
By closing the bleed off on a pumping stroke I can get different injection timing (to some degree) and get fuel metering depending on length and timing of the bleed off cycle.
Could rusefi control this?
I'm not sure what solenoids would be suitable for this application, as a big pump will need quite fast actuation on low load, maybe stages for low/high load would be needed.
If this not possible, could rusefi control the throttle/fuel metering of a helix plunger pump instead?

Re: Mechanical pump control
At the moment rusEFI is a port injected gasoline EFI touching GDI.
Moon landing has happened how many years ago? With proper resources sure thing many things are possible.

Re: Mechanical pump control
Ok.
Would be neat with a system that works with diesel engines as there are almost no standalone systems and no budget alternatives.
Not sure what voltage the vw PD use but I guess the GDI4 could drive CR diesel injectors.
Even just a simple electronic throttle for mechanical pumps would be useful as just using the throttle pedal to get a good AF ratio could be hard, on other hand progressive linkage could help and over fueling is maybe not the worst either.
But for gasoline I have a Kjetronic mechanical system too, would be need to have electronic control of it instead of trying to make analog mapping, which is a pain...
Using a stepper motor or something like that instead of the mechanical MAF sensor...

Re: Mechanical pump control
I suspect it's simple enough control that flexIO could do it. I think it's almost the same as taking RPM and spitting that out as an analog or PWM output.

Re: Mechanical pump control
PnP setups are of no interest for me but thanks for the offer.
I'll look into MFI some other time I guess, it was mainly just a thought experiment.
I have been looking on the board of the proteus.
Way more complicated than the board of my MS1V3.
Lots of tiny components, can't be easy to put that together and no jumper cables or anything?
Looked at the jlcpcb service, but I can't make sense of it, the zip file is uploaded. But I don't know where the parts list or the placement is to be uploaded and all the other settings doesn't make sense to me at least... Just too stupid
Not sure how to source all the components, are there any wendor in EU that sells a complete set of components so I could try to soldering them together myself without jlcpcb?
