Do you have check valves or a Missing Link?

I have neither, is that the problem? Will the missing link keep me from bucking in lower rpm boost transition?

What are you using for fuel management? If you are using an FMU you will need a missing link/check valve.

I am using the SAFC2 for management. It is running very rich and the SAFC2 doesn't lean it out enough. I try lowering the fuel pressure and it helps in low throttle but it isn't enough pressure while in boost.

What do you think I am doing wrong?

I would keep the fuel [ressure as close to stock as possible.

What are all of your settings along with injector size? The S-AFC should allow you to lean it out more than enough unless you are running 750cc+ injectors.

I am running 450cc Mitsu blue top injectors. Endyn Bosch 405lph fuel pump, 8AN SS fuel line from tank to engine. AEM high volume fuel rail. Aermotive AFPR.

Will the CEL cause me to run super rich? I try running factory fuel pressure and it floods out and won't rev past 4000rpms.

Do you think the CEL is my problem?

DON"T boost while the cel is on. You will not get enough fuel for boost. You have problems with your settings somewhere. What are your settings on your AFC?

Dr Boost

My SAFC2 Setting are:

Low throttle rpms High Throttle rpms
1600 -47 -38
2000 -43 -36
2400 -43 -35
3000 -43 -33
3400 -42 -33
3800 -42 -33
4000 -42 -30
4200 -40 -28
4600 -39 -28
5400 -31 -25
6200 -25 -25
7200 -27 -25

Dec Air is Ne1 10% and Ne2 10%
Th point is Low 71% and High 72%

Question what is the sensor type for a B18B1 Integra engine? It doesn't have a MAF meter like eclipes and Nissans, so is the Sensor type Hot Wire, Flap, Pressure, or Karman?

Sorry for the length but I have to know what the problem is cause I get the freakin CEL everytime I boost.
