If all you need is for water to follow in proportion to fuel, then this is actually pretty simple. If you've got a valve picked out, then it's a no-brainer to get the electronics working. Just make WI PW = INJ1 PW when MAP > x.

Hell. Somebody wants to send me a valve with a 300cc nozzle, I'll build you a controller.

So you want a frequency controlled valve?

It's looking like the MS's WI output is sync'd to the main injector pulses. So I'd need something that'll work in the 40-125 Hz range. No good...

I've gotta figure out if there's some way for me to get either a higher-frequency PWM or an analog voltage out of the MS that rises in proportion to total fuel...

Yeah, I guess I'll have to track him down on the other list and see if anything became of that.
