Does anyone know how to adjust the PFC to lower boost? I have a full exhaust and sometimes I can hit 14 psi. I want to get it back to 10, someone said something about duty cycles or something... any info would be appriciated

via commander

go to settings then boost..

youll have 2 settings to play with for setting pressure

pr is for your primary boost value

sc is for your secondary boost value

you set your pressure here

70kg/cm2 = 10psi as reference..

adjusting your base duty percentages allow you to achieve your target..

awesome, thanks a lot. is there a book or reference manual for this stuff?

u should have received it along with your pfc...

I just went out and looked at the settings I changed



pr

1 to 70 at 56%

2 to 70 at 64%



I dont know what to do with the secondary settings. or even if my pr settings are correct.... any info?

the first number is your target boost. the second number is your duty cycle % that changes how fast it opens and closes the wastegate. you have to play with it a little bit....
