Fueler, how to make your own.

Do you want to be able to add more fuel only where you need it?

The Andial fueler uses a frequency valve to lower control pressure under boost. However, there controler can only be set to trigger at given boost level.

Instead you can use an additional injector controller to drive it. One like you can get here:

This needs to be connected to a lead for an RPM signal, 12 v power supply, and to the manifold for vac'boost reading between the throttle plate and the intake valves. I mounted mine right on the intake manifold as there is a lot of air flow in the area to keep it cool enough. Andial puts there's under the seat.

Now you need a frequency valve or injector to bleed off the control pressure. I bough my plumbing from Andial with out the there controller. However if you are resourcefully you might use something like the following:

Now, you have to program the controller. I started mine by using a remote Motec wide band A/F unit. You just need to enter a duty cycle number in the cells at the rpm and boost points where you need more fuel.

I went a step beyond and disabled to boost circuit on the WUR. I used my system to total provide any added fuel. Further, I used a drop and catch strategy to get the metering plate out of the way ASAP to make a big reduction in lag.
