Question Blitz DSBC settings


Has anyone installed a Blitz DSBC boost controller in their WRX yet?

I just installed mine yesterday, and am looking for some advice on the settings...

I currently have it set:

Boost: 20%
Warning/Limiter: 1.05Kg/cm2 (dial-back -7%)
Gain: 5
Scramble: 0/0 (off)

Could anyone explain what the scramble setting does? From what I gather, it will promote a boost spike of a certain ratio for a certain number of seconds. Maybe I'm thick, but I thought this was bad? Anyway, I turned it off!

Any help, much appreciated!


Just changed things a bit as the above settings seemed to be too conservative - i.e. only hitting .5Kg/cm2.

New settings:

Boost: 45%
Warning/Limiter: 1.05Kg/cm2 (dial-back -7%)
Gain: 5
Scramble: 0/0 (off)

With these settings, I'm hitting a peak of .78Kg/cm2. Does anyone know what the stock Kg/cm2 setting should be?

I can't think of my settings right now, I'll check when I get home and post them. I have a few mods though so of course settings will be different with your mods.

I have the unit set:
52% boost
0 gain
1.07 warn

Seems to work fine. The solenoid clicking is somewhat annoying though.

I must say I am pretty confused by the DSBC unit. The readout is in kg/cm2, which is how many PSI or Bar? Is 1.00 kg/cm2 1 bar or 14.7 PSI or is the Blitz outputting differently? What good is the boost gauge on the controller if it does not give a real boost reading which we can read?

Also, where did you guys mount your units? I put mine in the little blank silver plate over the radio to the left of the cupholder. It is a really cool place to have it, though we did have to cut the plastic to mount it. Still, it is right in front of me and very readable/accessable.

What about the clicking? Do you other dsbc guys have the clicking under the hood as well? Does it get any better with time?

Check out my site, under the DIY Mods area. The first link takes you to a calculator page...

calculate to your hearts content.

Fast Facts...
The stock wastegate is .6 kg/cm2

~13.5 is .95 kg/cm2

1.10 kg/cm2 is around the 15/15.5 area..

If you scramble to about .5 above that your pretty safe. With out some sort of octane booster you are playing with fire above 1.1 kg/cm2 guys... You could run fine... or KNOCK HARD. Your call!

P.S. these are the settings I run on my EVC IV..
