well i have a set of 380cc injectors and i want to install them now but i'm using the LMS i-manage as engine management and the problem that i'm having is that when the car is not in boost it runs off the cars ecu and when in boost it uses the i-manage to let the extrenal fuel pump know that i need more gas...

what i wanted to know is does anyone know how much voltage i would need to drop the injectors when not in boost for them to run like my stock ones? i plan on install some resistors to do this but am unsure which ones i need...

thanks for the help guys

 

Andrew,
What psi were are running? You should be be to raise your fuel pressure at WOT and still keep the stock ecu at idle. I would pay attention to off throttle tuning though, stock ecu wants to go lean. Give me a call and I can help you figure it out. Or ship the car to texas.
