Grimmspeed electronic boost control solenoid target boost

welaish · Apr 25, 2014

I installed grimmspeed EBCS, according to the instructions manual I have to reduce the WGDC INITIAL AND WGDC MAX by 30%. So I reduced and tested.

Reached 0.68 bar = 9.86 psi

So loaded the stock map and reduced 20%
Reached 0.76 bar = 11.3 psi

Loaded the stock map and reduced 10%
Reached 0.85 bar = 12.32

Loaded the stock map reduced 5%
Reached 0.92 bar = 13.29 psi

So I finally installed the original stock map
Reached 1.06 bar = 15 psi

So i am wondering is that normal and why they instructed us to reduce the values by 30%!!
I am 100% sure of the installation, and i removed the restrictor pill as well. Please advise thanks.
The car is stock WRX STI 2012 except a crawford AOS can only.

The car is designed like that 2011 EDM and above you dont need to reduce the WGDC table.

Interesting because that's all correct it should be about 30% reduction

Thats what i am saying exactly, i ended up using thr stock map which is 100%. Not reduced. Something wrong here.

Ewg or iwg?

How did you install the ebcs? in 2 port bleed mode or 3 port interrupt? If its 3 port then yes you will need to reduce wdcs's by approx. 30% I would double check you hooked it up correctly and make sure you pulled the restrictor pill out. Let me know how you have this hooked up.

so in 3 port interrupt what should my wgds be reading on average ? EWG setup

I thought an EBCS required a tune (and not just adjusting values by a non-tuner).

These are the tables that is required to be tuned. If the device was using the origin stock map this means it should over boost but it does not. Also i was logging and analyzing the logs.
