What were you thinking to use as a controller?

Doubling the current load on one of the injectors will burn something out most likely.
Use a solid state switch driven by one of the injector circuits.

Originally, the #1 injector, and possible the #4 injector. Just putting a second inline.
I'll probably just take the solid state switch, and have it register the #1 injector to send power to the water injector!! That way the whole thing will be self run. |

The only problem is when water injection is ran on gasoline powered engines all the time is it usually lowers fuel economy.

I can't figure out why it would lower fuel economy, since it's meant to overcome knocking while running leaner. But anyway, I'd rather not resort to it while the engine is still cold. |

It's best to try to run lean with out water first.
It seems a lot of people running water don't try or don't know how to lean the air fuel mixture.

I would think that you can advance your ignition timing a bit with water as well as running lean. Haven't played with a gasser in a long time.

How are you going to run it lean?

Sure, but even if one is able to lean the mixture while not having knock issues the water injection could be used to keep NOx emissions under control, and eventually try more extremely with the lean-burn.

Much like it's done with ethanol  |

I was thinking to change the resistance of the IAT sensor (Intake-Air-Sensor) with a bypass of a set value to force a temporary lean condition.
There are EFIE's for sale from the HHO world that should work for water-injection as well and they are not so expensive.
After a car swap, I've realised how uneconomical my car is and might do something about it now.
