Well...kinda. 15lbs of boost = 15lbs of fuel, that's kinda low. Okay, I'm still trying to get this whole MS thing down: running big injectors at stock fuel pressures (43psi)and decreasing the duty cycle VIA MegaSquirt will make it idle good. And using the software you adjust your AFR to what you want. The MS uses the different sensors to determine the rate at which it should fire, electronically. Now fuel pressure is raised or lowered mechanically by the FPR, but how do they relate.
Maybe I'm still in the SFMU/ bigger injectors thoery since I'm running it. Someone really should post a VFAQ thing on how it works. Thanks
