Ford Festivas

[Advancedynamix]

I am currently building 4 ford Festivas with various mazda engine combinations. Looking to experiment with multifuel injection (several different fuel delivery systems working together on one engine). I've wanted to be able to build my own management system for a long time now, so I'm really looking forward to learning from this group.

What exactly do you mean by the multiple fuel systems? As in different types of fuel or different types of delivery? Sounds interesting either way and I'll try to help out if possible, I know a lot of the theory and a decent bit of the physics/math that apply to engines, injectors, carbs, tuning.

I've seen people use propane injection in a diesel which gets better fuel economy for a bus or large rig. I'm guessing they mean something like that.

Both different types of Fuel and different types of delivery on one engine. I already run Gasoline and Methanol through different systems, but I'd like to integrate them with similar controllers. Right now it's two completely different systems. I would like to do a similar setup with Gasoline and e85. Two separate fuel tanks and systems. This would allow me to utilize the advantages of the ethanol fuel under high engine loads (turbocharged engine) but not have to compromise fuel range or bottom end torque. This also allows appropriate system design for each type of fuel, rather than compromising in order to be able to run both fuels.
