Anyone with a SORTED PFC prepared to post the low load maps?
I have a V3 STi with a PFC, spec as follows:
HKS Headers
Decat Downpipe
Full System
Blitz Induction
Boost Controller at 1.35 Bar
Standard IHI VF22 Turbo
The car has been on the rollers at Gt-Art and had the full load rows fettled to suit. However the car uses more fuel than on the standard ECU during normal low load stuff.
I wonder if any one can be so kind as to post info on there low load maps (say upto row 10 both ways) aswell as there airflow percentages to give me a good starting point before going to the rollers again.
Dont worry....I will be checking everything as I go and wont be blaming nobody should I blow her up!
Thanks in advance.

Would suggest that you get yourself a wideband if your going to be removing fuel and some way of monitoring EGTs so you know just how far you can safely go.

If running closed loop doesn't really matter, just make sure the ignition timing is adequate in the low load cruise areas (typically over 40 degrees at typical cruise RPM). Fuelling numbers are not comparable between specs of cars with different induction/MAF/fuel system and a load of other differences.

Thanks John.
Is it true the
at the PFC is mapped for 440's on a different MAF out of the box?
This is what everyone says, but my airflows seem about right (4% is the most I have had to reduce the higher regions by).
