pfc boost control duty settings
In the boot settings menu, you can change the Pr (primary) and Sc (secondary) target boost pressures and solenoid duties.
Which solenoids do these settings correspond to? I am assuming that Pr is the wasgate solenoid. Would Sc be assocaited with the turbo control solenoid?
In addition, does the PFC retain the stock ECU's pre-programmed settings for the charge releif, precontrol, and charge control solenoids? (5,500rpm initiation, etc)
Lastly, should I change the target boost level or the solenoid duty level. Or both.
No, I don't have a datalogit

Pr(primary turbo) is for the pre-control
SC(secondary turbo) is for the wastegate.
I have no idea what the stock ECU settings are for those valves, but it is fairly close in the stock ECU.
The target boost is basically for fuel cut, if you run something like 0.15 above it, it will hit fuel cut. I wouldn't change either if it is a stock car and you don't have a way to check AFR's, etc.

Ohh yeah, target boost is for fuel cut only... that makes perfect sense.
But what about the duty %? Would changing base duty increase my max boost pressure?
Basically I just want to increase the boost level to 14-15psi.
I have all other supporting mods, wideband, etc, limited tuning knowledge (AFRs etc). I just don't know how to make the PFC do what I want (ie. 14psi)
