Default Re: FAV valve specs

what ECU are you using. Does it have a high-speed PWM output?

Thanks Richard. Are you saying it is meant to be driven at 5V? Because I was testing at 12V.

Megasquirt 3 is the controller I'm using. I'm driving the FAV from a spare injector channel. Channel is switched to ground so I could run it at 5V instead.

It has to be driven at 12-14V, but with a high speed PWM solenoid driver.
Send me a circuit diagram of the circuit diagram to: richard "at" aquamist.co.uk. I will help you to get it run right.

For the record, Richard really knows his stuff and called me, gave me some suggestions on improving the circuit I'm using. Top man. I'll repost some results once I've altered it and tested it.

Richard i want to get your valve as well.

I too will be using 100 % pump but very FAV duty cycle and PWM.

My only concern is my system is all 1/8 NPT. How can i integrate ur valve ? Adapters ?

Also what is the effect of this fast switching on the pump ? Due to these mini hammering effect ? Is there any ?

How long would the valve last ? Also what is the response time of the valve in ms to fully open and to fully close ?

Regrettably I have taken this item off the "direct" site. It is becoming a burden for me to support this item, in terms of mechanical and electronic requirements to drive this valve properly.

Post Re: FAV valve specs

FWIW I myself could run the valve on its own but I choose not to do so, rather trusting Richards already worked it out as a package that works. I use his complete kits > see here,
https://www.youtube.com/watch?v=7OzQJwGw86Y
integrated into my own Syvecs/LR ECU packages, they work and are 100% reliable, no stress, no need to do something where the hard work has already been done.

The opportunity cost to me means its just not worth stuffing around.
I can verify after using many of the kits that they do work as stated and are very repeatable, and dependable, to date never had a failure and more importantly the accuracy for fuel and knock control with increased performance is second to no one else offering (WI systems).

Great job Richard
