Off topic...GM TBI on a jeep motor...anybody???

[k5-newbie]

I have a buddy I wheel with and he wants to have a Chevy sooo bad, he has rigged up a 4.3 TBI setup on his Jeep straight 6. We got it to fire up and pump fuel but the injectors are pumping too much and we realized we had a 12V reference pulsing the injectors which is too much. Now, I believe ( and I could be very wrong here) that the injectors are supposed to see around a 10.6V reference to pulse off. Is this true and also, does anyone know a good tech article I could read to explain things a little better?

Again, I realize this is not totally Chevy related, but I am trying to help him leave the dark side

All help is appreciated.

One side of the injector is wired to +12 all the time that the key is on. The ECM supplies a pulsed ground to the other side to fire the injector.
