why can't i get my a/f down!!!
this is a supercharged h22a at 6psi.
i had stock injectors, and couldn't get richer than about 14:1.
i put 370s in. according to all the calculations, it should have taken about 70psi at the most to get a nice rich mix.
in reality, it took over 90.
the electronics included with the jrsc are sending a 2.6v map signal to the ecu, which is pretty close to atmospheric but not quite. i can bump that up to 2.9v or so with the vafc before it starts bogging, but it really does not have too much of an effect on the a/f.
it seems very very wrong that it would take 90psi on 370cc injectors to put down 220whp and 180lb/ft of torque.
any ideas what's going on here?
