Greddy Profec B Spec-II settings Options

[speed-CCNP]

I just installed a Greddy Profec B Spec-II I need some help tuning the new toy. I have a 3s-gte so 12psi is the max I should run.

10psi= 68kPa
11psi= 75kPa
12psi= 82kPa
13psi= 89kPa

Boost Mode Lo
Set 38%
Gain 10%
Start Boost 0.65 (x100kPa) (range:0~3.0 x x100kPa)
Warning 0.75 (x100kPa)
Limiter L.20%

Boost Mode Hi
Set 42%
Gain 15%
Start Boost 0.75 (x100kPa)
Warning 0.82 (x100kPa)
Limiter L.30%

I'm not sure about any of the settings. Are there any stickys on this?

Every car is different, but here is the basic idea.

Set: This is the boost u want to run
Gain: This is the responsiveness and spool up of the turbo
Start Boost: Also responsiveness.
Warning: What boost do you want the limiter to kick in, in case you boost too much
Limiter: How much you want the boost to be decreased by, in the event of boosting too much.


So basically, set your SET to the boost level you want to reach. Then Add as much GAIN as possible to get the most responsive spool up. If you add too much GAIN, you will see boost spikes. The START BOOST should be set about .75 bar, like you have it. Change the Warning to 1.00bar and the limiter is probably fine at 30%. Dont set START BOOST and WARNING too closely, because that can cause inconsistent boosting.

Make sense?
