I've spent a decent amount of time reading on how.boost tuning works...but i wanna make sure i got it right and understand it properly

The goal: Finally install my GS EBCS and to run psi-based boost instead of load based.

What I did: I followed these steps to turn on psi-based http://www.evoxforums.com/forums/showpost.php?p=1831570&postcount=6
Also, I made sure that my atmospheric boost is set to baro level (14.4 for me, but whatever I log my baro at).

Then for installing the BCS, I 1) turn off all passive solenoid maps, 2) reduce my reactive solenoid base wgdc by 50%, 3) I zero out max upward correction and leave max downward correction alone. I also changed my correction interval from 7 to 2 or 3.

My understanding of things: I read merlin's boost guide of how boost control works so I think I have a decent grasp of it, but using the settings I mentioned above, I would still use the reactive solenoid base wgdc to fine tune my boost curve. Other than that, I would adjust psi values in the Direct Boost category. Is there anything I'm missing? Overlooked? Or is my understanding wrong? Any help is appreciated.

 

The oem boost control system is already sort of pressure based. Just think KPA instead PSI, with a dose of VE tossed in (from 3x map calc tables). Set your desired boost using your WGDC tables, then after you have your desired boost, adjust your target load tables to match. Keep in mind the correction table applies, so frequently you will want to have your target load set slightly above your actual load. If the rest of your ECU is tuned correctly, then the air mass going through the engine will be relatively constant, as in boost pressure will drop with temperature, or go up with temperature, to a point, depending on the capabilities of the turbo installed.

As a general rule, the GS 3 port will need to start out at about 60% of what you would be at with the OEM bcs system (assuming proper pill removal). There is also frequently a "weird" spot, mostly due to the GS using the incorrect size fittings (to small), so it isn't as linear as some other MAC valves with proper fittings and hose sizes, like the Cobb.

Not trying to sell you on not using PSI based. Just don't want you to write off load based, because load based works really well.

 

Ive read over load vs psi based boost tuning. Its just more simple to do psi based vs load based...

 

If your looking for the most basic way to do it ....then you have it right
However to dail it in perfectly and get ecu/gear dependant I suggest reading heavier into Merlins guide.
Also as previously stated you need to have a pretty spot on tune as is. It would be advisable to log,log,log once you've made any changes.
Also look into the psi adder function
