Stock Injectors = Maybe? Big NO?
Hey guys, looking for some opinions/facts from you!
The main purpose of those questions are for the ability to run the stock ecm at anytime I need it without injectors swap. So here it goes; One year ago I got tuned on a mustang dyno with AEM fic. Stock internals 200,000kms engine Garrett GT2252 370cc deathswerks injectors 5.75psi spring We made a safe 145whp / 145wtq Couple months later the fic stop working, I remove it and run the stock ecm. No surprise, the stock ecm is having a hard time running the bigger injectors which are twice the size of oem... So I swap the oem injectors back in the rail and run the car turbo'ed @5.75psi with stock ecm. time goes on... Nowaday I have a brand new PnP harness with a brand new AEM fic plugged in the car, no tune. Running the car stock I see that much of the problem is the Stoichiometric air/fuel ratio during acceleration! It removes all the low-end power... During open loop, a/f are allright until about 1/2 - 3/4 of the throttle pedal. So my idea is theres not much missing for the injectors to be ``allright``. I don`t think the oem injectors are already maxed out by the stock tune... Maybe I could get tuned again with the sames number with stock injectors. That way, if anything goes shit again, I can simply use the stock ecm without any fuel problem. Thanks, and sorry for my poor english! |
