I can figure out how to change the boost with the commander. Under the boost menue I see two settings, I assume you can program two seperate boost settings. Mine looks like this:

1. Pr 0.80kg/cm2 62%
Sc 0.75kg/cm2 70%

2. Pr 0.90kg/cm2 62%
Sc 0.95kg/cm2 70%

I don't understand how this works. I assume the percentage is the duty cycle of the wastegate solnoid, but why are there two percentages for each boost setting? It think I recall that increasing the percentge lowers boost. What do the Pr and Sc stand for? How do I know which boost setting is curently being used? Right now I am seeing about 12-13 psi on my A-pillar mounted boost gauge, depending on the gear. I would like to turn it up to 14 psi. If anyone could explain to me how this works I would really appreciate it.

I meant I can't figure out how to change boot settings.

Pri primary turbo
Sec Secondary turbo

there are two boost settings and you can choose to use either one.

When your in the boost setting area, the #1 should be lit up if your using the first boost settings....If you want to drop down to the 2nd boost setting, just press the down button. Now #2 should be lit up...Now your on the second boost setting.

To up the boost, if your on the #1(first setting), then press the arrow to the right. The cursor should move to the 80...Now press up to get the boost higger or lower. then back to #1 Do the same for the second setting.....

Duty cycle are tell you how much the actuaators are working and will make the turbo come online faster.....with a higher duty cycle...Hope all this helps....

Boost setting:

first number is max boost/target boost -- 0.25 over and you hit fuel cut

second number controls the solenoid(s) and is the base duty cycle. You have to manipulate this number to actually change boost.

will the PFC jsut cut fuel, or will it adjust the WG to control limit the boost at the same time? if the formaer shoudln't one keep the fuel cut setting at maximum?

Will I believe the PowerFC has some "learning" capabilities, if you outflow your wastegate, then you need a safety system. Also if something comes loose on your wastegate (vacuum lines!!), then you need a backup system.
