how-to: ECU-based direct boost control

i don't think i do because i checked the numbers to ports like 3 times to make sure it was right. it's brand new too. don't they do a check before they ship them? that's why they have the inspector sign a card that goes in the box. do i need restrictor pills?

A good amount of people hook up the ports incorrectly and that will get you WG pressure no matter what you do in the ECU. What ports do you have going where?

my car is stock 9 turbo/map o2 housing/turbo back/ic, currently running mid 60's WGDC in the midrange and running up to mid 80's to 7k to produce 24psi tapering to 20ish...have had to drop my wgdc's 5-8% since o2 housing install.

well i finally got around to checking the install, and it's fine 1 to intake, 2 to wastegate and 3 to turbo. ???? it has to be something with my ecu then, i'm running tephramod v7 and i've read the how to for boost control but it's not doing it, what else should i be looking at?

Kind of lost on this...
Running Tephra V7 and ECU controlled boost on a BW 7670 w/ Dual EWGs.
Was running the EBCS as a 2 port system (top port of EWG was vent to atmosphere) car was extremely laggy but made boost and held great at roughly 40% WGDC. It just wasn't very consistent. Target would vary between 18-25 lbs.
I changed the WG plumbing to a 3 port system as I was told it may help with lag and more consistent boost curve. I zeroed BEC table and set WGDC to 5%. No it's boosting to 30 psi consistently at 5% WGDC?
When I was running a stock turbo I had to drop my boost adder to 10.6 to keep the stock turbo from over boosting at just 50% WGDC despite living in Atlanta, GA and no where near that high of an elevation. Do I need to just keep dropping the Boost Adder? My target boost is set at 24.9psi

Solved my own problem.. I had run the EBCS backwards. Followed the picture diagram above from JeffBeagley and its responding great. even running the correct "atmospheric pressure values per evelation as discussed by mrfred...

Hello.
I can't see the code that we have to add to our xml files. My ROM is 94170015, could someone please help me? I have tried on many computers and phones, with the same result. I need the tables for Ecuflash, also the scalings, and also the code that we have to add to Evoscan. Thank you very much.

Found a solution. By quoting the message where I couldn't see the code, I can see the original raw text. 
Still, i don't know why I am having this issue. It is with any thread that contains code.
