Extra Injectors Control

[Joryn]

Just wondering how many of you have done it?? I was thinking of for now running the 2 inj i was gonna run off a pressure switch so they would turn on at 15 psi. but it would also have a 2 stage boost seutp. stage one would bel ike 10-12 psi and stage 2(with the EI's) would be 18-20.

does this method work or does the switching onof the injectors at 15 psi run the mix too rich and bog the engine? thoughts?

well, i can't see how it'd bog THAT much. i say try it, after all, too much gas is better than not enough, and worse case is you go and buy another pressure switch for 17 psi. that's just what i'd do.

why run the extra injector bellow 15psi, computer supplys more then enough fule till then. one cold start injector to about 4 extra psi.

I've run 2 additional cold start injectors (Saab), it worked well. The engine didn't bog. The injectors were good for approximately 3 - 4 lbs additional boost per injector. I staged them using pressure switches.
What type of injectors do you intend to use?

Better bogged than blown up.

Amen to that. there is no way im running more then 15 psi without adding injectors, my car starts to lean out right aroudn that mark already. so definiitly using it there.

As it stands i got the injectors from 2 different cars, i think an audi(VW) and i cant remember wherei got the other.

I would like to stage the injectors but for now i have all the equipment to do it this way. im planning on designing a better(heh fancy) controller later that will do just that, but if this will work for now, im all for it.
