How To Leaner My Car With The Pfc?

[BNR34boy]

I tried to leaner my car(BNR34) with the PFC, but I can't!!

I have the following mods:

HKS valve spring step 2

Jun 264 cams IN/EX

Jun cam sprockets

Jun Oil pump

HKS 1.2mm Head gasket

Nismo N1 turbos

Nismo fuel pump

Apexi Power FC

600CC injectors

Anyone could give me some ideas? When I rev up the car to 3000rpm, the engine light flashes and would go up further?

please help!!

How do you know it needs to be leaner? The flashing engine light possibly indicates overheating of the catalytic converter- probably caused by lean A/F.

What does the O2 sensor say on the dyno?

PFC flashes the engine light when it detects detonation, sounds like you need a tune.

As Adriano said, sounds like its already running lean, and if its flashing at 3000rpm - i'd be very worried about the tune

what are you actually using to monitor your A:F ratio?

please go and get your car tuned.

I am using innovative motorpsorts's wide band sensor and its telling me its rich. Also, from my muffler, it coming out a lot of black smoke. So, i think I need to leaner the car.

whenst the last time you calibrated the sensor? how old is the sensor? how much are you changing the fuel map (how much did you take out, as a percentage of the original nuber)? did you take a bit out, then test it, and repeat, or just take heaps out and now its having that problem? did you at least save the previous map it had before you started messing with it?
