newbie need help with fmu adjustment

[RaymondG23]

hi I am new to this forum and need some help. I have a 420a custom turbo eclipse its a 1995 and have an fmu on it and need help adjusting it,the problem i have is that it has two knobs on it one on top and one on the side.i dont know what brand it is and have looked everywhere and found this forum so can someone help.
the pic of the fmu is just like the one i have but cant find a brand or instructions.

Its a Billet Cartech FMU 4:1 aka BEGi FMU 4:1 ratio ratio if that helps any.

That does look like a BEGi regulator, which if it is, the top "knob" will adjust your idle fuel pressure, while the side "knob" adjust the rate at which the fuel rises.

EDIT: Look and see if it says BEGi on it. And if it does its not a set 4:1 like mention above, but it is an adjustable rising rate.

wow thank you very much bagged420a and poonman i have been on four different forums and nobody could give me a straight answer.

one more question on the fmu.
when i drive my air/fuel ratio shows i run lean and also when i drive and step on it the rpms go up real fast and the car doesnt even pick up that much.
please help again.pleaaase
