how-to: ECU-based direct boost control
The way i did it was turn everything off and work on getting the baseline WGDC to where it gives you the boost you want. Then turn on correction and target boost to what you want where you will hit it.
I have a quick question regarding the Boost Adder. Let's say you live at 1000 ft above sea level = 14.17 . So I set my BoostAdder as such, but then I drive to work and it's 500 ft = 14.43. Will this ecu boost system adjust itself? If not, won't this cause overboost?
yes it will but by a very very minimal amount. you are talking about 14.43-14.17= .26psi of overboost.

The car will go to higher "gauge" boost (boost relative to local atm pressure) at higher elevation, but the "absolute" boost will be the same which is what matters. Another way to put it is that the higher the elevation, the greater amount of gauge boost that can be run.

The "min temperature for full boost" item is a bad definition from the early days of ECUFlash. If you changed the value, you should change it back to stock and then delete that definition from your xml file.
paste code where question
Can anyone give me some guidance on the question below. Thanks

Double checking my work on some of this stuff, I don't seem to have added the code from the 3rd post to my evoscan file.
<DataListItem DataLog="Y" Color="" Display="Boost Error" LogReference="BoostError" RequestID="8A" Eval="0.0241*x-3.087" Unit="psi" MetricEval="" MetricUnit="" ResponseBytes="1" GaugeMin="-5" GaugeMax="5" ChartMin="-5" ChartMax="5" ScalingFactor="1" Notes=""/>
<DataListItem DataLog="Y" Color="" Display="WGDC Correction" LogReference="WGDCCorr" RequestID="8B" Eval="0.5*x-64" Unit="WGDC%" MetricEval="" MetricUnit="" ResponseBytes="1" GaugeMin="-50" GaugeMax="50" ChartMin="-50" ChartMax="50" ScalingFactor="1" Notes=""/>
Where in the file or the tags specifically should it be pasted? The ending tags are like this.
</Mode6>
</ecu>
</vehicle>
</EvoScanDataLogger>
Sorry for the newb'd question, but I am going through everything I learned again and again, and finding little questions.
Thx

just add it anywhere grouped with the other logged items. It depends on which version of evoscan you are using.... If you aren't comfortable with where to put it look for the first instance of RPM in the data.xml and add those lines just below it (this should be the Mode2 section). You can then re-organize as you please from the GUI.
fostytou, Thanks. Got it did it. Placed the lines in the first mode 2 section and then experimented with moving them around. I already had a line in there for the WGDCCorr in there and that was causing an error. More comfortable with the data.xml file now as well. thanks

So I'm running Tephra's v5.10 patch and trying to dial in my base WGDC boost curves (no error correction yet). The problem is my boost level changes. The first run after the engine has warmed up would hit 25psi and the boost curve looks good. Next pull would always be lower, usually around 23psi and the next pull would be around 22psi, where it seems to say for the most part. Anyone else have this issue? I have no idea why it does this.
The vacuum lines are good (replaced all of them to try to remedy this) and they are DEFINTIELY in the correct configuration on the BCS ports.
