hi ed,

if you tap into inject wiring, you might want to link to two injectors as the toyota ECUs i've seen run 2 banks of injectors (e.g. non-sequential).

but if you've got the time/enthusiasm, there's a few variations on the standard Megasquirt that supports the kind of thing you're after, e.g. dual table ECU (drive normal injectors on table one, and table two drive extra big injectors such as water/meth inject or a second bank of petrol inject for moments of panic/testosterone etc)

thanks charles Smile

thats getting all a little above and beyond in terms of complexity for a si ple water/methanol misting system Smile

im running a shurflo 45psi pump and an industrial micro misting jet (50micron spray) rather than an injector per se.

switching it will be donr by a combination of an rpm switch, and a MAP switch. i just need to figure out the MAP switch circuit Smile

cheers
ed
