hmm just thinking, if the system is designed to maintain a single constant pressure - then the pressure sensor will probably have a hysteresis kind of curve - similar to a narrow band EGR - which will make an OEM sensor unappropriate.

I could still use it on the race car for the same benefits of ...

thanks for the reply.

So they do pressure feedback control more to maintain a constant pressure, and prevent any drops / increases in pressure which may deviate the mixture from what they want (when not under EGO feedback control i guess?)

I know some MOTEC fuel injection computers use fuel rail ...

Hey guys,

I was given a proposal by our formula SAE team:

To design a feedback control system where you regulate pressure in the rail by measuring the pressure using a sensor and modulating the power applied to the fuel pump.

Then you could use a map sensor (or TPS in our case) or rpm as an input ...

Thanks, although i need to look at some drawings and i am still perplexed as to how a magnetic feild in either direction can pull against a spring that can only open in one direction.

I have mucked around with some AC valves which were exactly the same, no matter which direction of current flow the ...

If you reverse the direction of current you reverse the magnetic field which would push the needle away from the spring / port if you connected it the wrong way?
