New Problem.

Engine check light come on when ever i get in boost, about half pedal. XFI says " inj duty limit "
That seams wrong, i'm running 60 pound injectors. Fuel press is fine.

Anyone. Thanks..

Are you sure the FP is fine under boost? 1 lb boost raises FP 1 lb?

What boost and HP level are you at?

Found the problem; My fuel pump is only getting 3.6 volts from factory harness.

inj dutycycle ?

Hi. sorry for long delay.
Instaled ex. pump (Auromotive A1000), tank sump, an8 fuel line, still goes 100% dutycycle on part gas.
One thing, injector opening retard was set at 40. Acording to FAST, bank to bank swould be set at 0. Could this be a problem??
One other thing, it has a slight stumble off idle. I tryed rasing AEfuel vs TPS, AEfuel vs map,adding fuel in base fuel, nothing. Maybe lower inj opening time from 1.0ms to .09 will help idle better and of idle stumble ?

Thanks..

i had this happen to me as well
fuel pump was good
installed bigger injectors and adj map/ae and all is well
and 1.0 or .9 would be better than 40 weird...
