Please read the instructions for the best options for venting your Command Center. This is a very important step so do not skimp out. A hose to the ground is not a vent!
I am running a 350 with the 400 series and fuel command center. It has been up and running for a month. Today I tried adjusting a couple of the AFR’s and had the idle set to 700 and afr of 14.6. it seemed to be ok for a test drive. after sitting for an hour in the cool weather it would not idle, it only runs for about 5 seconds then the power to the fuel center turns off. Engine dies, starts ok, repeats fuel center power loss. Any ideas?
Check the vent line for any restrictions. Also be sure the set Pump PWM to 40 under ENGINE SETUP.
Why would fuel be coming out of the command center vent?
If you run too high of pressure into the Command Center you can blow past the needle and seat hence overfilling it. This can also happen if the needle is stuck open for some reason like debris.
I noticed the pressure going in to the FCC was between 8 and 9 psi more towards 9, is that going to be a problem?
Yes this can be a problem. Running too much fuel pressure into the FCC can cause fuel to blow past the needle and seat. I recommend using a low pressure regulator to dial your pressure to 6-7 psi.
Thanks, other wise running great, very happy.
