I got a code 45 which is either too rich or too lean. Im guessing too rich. My fuel pressure at idle is 52 psi. My fuel setup consists of 12:1 fmu, intank fuel pump, stock injectors. My question is, would it be safe to drive the car daily. and should I run it at track??

 

is your FMU hooked up backwards?

 

I thought that with an fmu setup you have to run an inline fuel pump instead of an intank.....that might have something to do with it. I could be wrong though, just trying to throw you a bone.

 

I was running a inline and the car ran like ****, switched to intank and it runs good. The fmu is hooked up right. I guess this setup is what is causing the cell??

 

Yea I had the same problem, I did the fpr mod to drop the fuel pressure back to stock and it was fine, but i also had my FMU backwards which cause my high idle psi. so I probably didnt need to do the fpr mod. I'm running the same setup, intake pump and 12:1fmu runs fine now.
