No boost signal at Power FC

[Cristian]

Im not making much if at all more then stock at the moment, still running standard boost.

But mods i want to do to get as much power as possible are:

GTR style plenum

550-650cc injectors

GCG turbo upgrade, 16psi

already have FMIC, but piping is 6 meters long, so will be redoing piping

3" exhaust from turbo back

upto to 250rwkw the stock airflow meter is ok

then from 250 to 290rwkw odd ish you can use the z32

then from 300rwkw onwards you can use the q45 airflow

the powerfc supports all of those from the setting, airflow, option

rb20/rb25 r33 is the stock afm

power intake is the apexi power intake kit (does this actually do anything different)

vg30 is the z32 afm

vh41 is the q45 afm

Actually ive got the Power FC boost control kit, im just missing the boost control sensor which comes off the manifold, does anyone know what i can use instead of the Apexi one which costs $200.

when you get the hiflow try and get a vg30 housing on the turbo instead.

forget the piping and plenum and spend that money on a set of cams.

go for a split dump 3" and make sure u have a bigger fuel pump.

the gtr plenum wont add any power or make much difference, and pipework wont do much, spend those on stuff that will, or at least has been proven to

Power Fc : $1100

Dump pipe $400

3 inch Cat $150

Air box $ 200

FMIC $1100

Actuator $200

Z32 $250

GTR Pump $170

HKS Turbo $1200

Tunes $500 (note this is plural)

Theres at least $5k there on engine mods to get it running mid 12's , not bad when you think of it that way. What else can beat it for the money?

i'm guessing that a standard map sensor will do. on my PFC that is what gives the boost signal. i have a spare one for sale if you want it.

hi cristian and others

i am still keen on getting the powerfc to read boost but not by using the boost control kit. the only reason is i would like to be able to have the boost on a graph vs revs on the same graph. i have my own controller but would still like to see the value. a stock map sensor in the same voltage range connected to the right pins on the boost controller plug in external socket should work, also trying the same thing with air-temp sensor. will update in a week or so

Paul,

how did you go with all the testing? any results?
