This fuel return setup confuses me...why not just run the 1300's and not have to worry about doing a fuel return setup. :think: anybody got a link to the 1300's
you want a constant flow of fuel without having the fuel rail to dry up and have pockets of air going through the injectors.

I was talking to Jay (Mucter) and said that any FI civic that's close to the 400hp range and up would benefit a fuel return setup.

Look at Matt (OBX4Life) set up with 1000cc injectors at 52% IDC (from what he tells me) at 12-14psi on a turbo.

All of what Fidel said. The fuel return compensates for boost and keeps your fuel pressure stable by bleeding off what it needs to.

And yes. I can re-check my logs but IIRC my highest injector duty cycle has been 53% @8k - 12psi

I was actually curious exactly what it was, so took a screenie of my last log.
55% @ 7800

Matt are you done with tuning the car?
Nah.. still hovering around 12psi. Vit may have upped the boost but I've taken a break from logging to get the car ready for its first show this weekend. It gets sketchy logging in 4th gear so I'm really taking my time with it.
