Wiring of FAV
 

Hi guys,

I have been using water injection on a turbo engine for years now, but as I am converting my old car to fuel injection, I realise that technology has moved on.

I have chosen a Haltech 2500 ECU and am going to control the FAV with a PWM output that mirrors injector duty cycle from that.

As I am not using the Aquamist controller, I need to know how to wire up the FAV.

A diagram with a short explanation would help greatly.

you need to drive the FAV with a hi-speed PWM channel from Haltech. Many tried using the aux pWM output and got bad results. Ideally use a spare fuel injector channel.
