FMU choice? help me out
i've started buying some stuff for my turbo project that i'm going to complete in about 3-4 months. My car is 99 EJ9 Civic with d14z2 engine... i'm going fo 6-7 psi and planning on using FMU becuase i'm in low boost range and can't afford better fm. My question is which fmu to buy i think vortech is good but should i use a 12:1 or 10:1 and why? what does the ratios stand for
thanks for any help

A 12:1 fmu will increase fuel pressure by 12 psi for every 1 psi of boost. Most people use the 12:1. I wouldn't go above 5 psi with an fmu but you may be lucky. Of course I have to tell you the usual that everyone here tells everyone that is thinking of using an fmu:
Chip your ecu and run uberdata, get larger injectors. Your engine can run more boost and be much safer than an fmu, and it doesn't cost much more.
edit: and convert to obd1. Ok just use the fmu and don't boost much.
