I have the setup sorted out.

I a using an arduino a canbus shield and an injector.

Keen to read more about your setup, and how you went with results...?

Just figuring out the las bits and bobs. I think all i need now are the hoses.

From the factory water injection.
Not for economy, just more power.
But the argument can be made that the water allows a smaller engine to run more boost, make more power, avoid requiring premium gas and indirectly allows better fuel economy. Yeah you don't want to run premium, it's up to 70 cents a gallon more than regular gas these days.

but is also lost by the pumping action of the tires

use a diaphragm pump to pump water to 50 psi or so. Run the line through copper, then heat it off the exhaust so the temps get up somewhere near 250 degrees or so.

then run it through a fuel injector, and inject it under the throttle body.

Piggy back the fuel injector off the main throttle body fuel injector so the pulse width is the same as the fuel injectors pulse width.

The idea is the water would follow fuel flows, which obviously is a pretty good indication of engine loads.

The higher temperature of the injected water means when the water hit the intake manifold it would pretty well atomize - you would not get pure "steam" per se, but you SHOULD get pretty good atomization, just like the fuel gets atomized by the injector pretty well.

ultra sonic vaporizer this is what you're looking for why not cut out the middle man???
