Questions on my direct port meth setup

[rotrex]

It could be that Richard suggest to use a direct injection inductive output set to 60-75V and 1.5A current limit the use or a Peak Hold Injector Output.
In both cases you would need to know how long the peak phase needs to be.

I have never used a FAV, only the HSV, so I am of litte use here.

For the latter, I plainly used a low side fuel injector output and 50 Hz. But the HSV is faster than the FAV. The latter needs 30Hz.
If you drive it faster, it will not fully open and close. this effectively turns it into an adjustable restriction with low pressure on the nozzles except at its mostly open position.
You want high pressure pulses at lower flow rates at the jets.
