fuel pressure? fmu adjustment?
I am running a mini me with a greddy turbo(19t) in my car. What fuel pressure should I adjust to for 7lbs of boost? And what fmu ratio should I adjust to? Any help would be great. I am running stock injectors/pump.

Re: fuel pressure? fmu adjustment?
48 psi
10:1 <-- Total guess...I hate FMUs |
Re: fuel pressure? fmu adjustment?
Thanks, I am running like 42 psi on a walbro 255, and the fmu is 12:1. So far so good, making great power for 10 lbs, no pinging, a/f's are great. thanks for the input

Re: fuel pressure? fmu adjustment?
don't mean to hijack your thread but what do the different ratios on FMU's scale up? I realize amount of fuel of based on vacuum but how does like a 12:1 to 10:1 and 8:1 all differ? I'm planning on running a FMU and 255lph fuel pump on my Z since MS is kinda out of my pocketbook right now. Would a adj fpr be ideal too?

12:1
means 12psi is gona be added per lbs of boost. 8:1 8psi/lbs of boost |
