Mrfred when you will find time can you please look also for the address for SHLR->SHLL for EBC at 88840017/16?
I think the rest of the definitions are correct and I just need the SHLR address for PSI direct boost control.
Thanks in advance

So if I use Omni 4-bar sensor and want to log "Boost Error" at the evoscan, should I change the "Eval" part to "0.02955*x-3.7825" rather than "0.0241*x-3.087", which is for JDM 3-bar sensor?
What exactly does BCS Re/De Activation RPM do? I tried searching for an answer but, didn't come up with anything. I'm trying to trouble shoot 9653 v7 direct boost control and wanted to better understand what this does. Thanks
WGDC goes to 100% when the bcs is not "active". So the RPM hits x and it deactivates the BCS. The RPMS drop below say 2100 and is off (100%) the rpms come up again to 2200 and it goes back on.
Reactiviate is low RPM threshold on and off.
Decativate is high RPM threshold on and off.
This is why it is important to set the deactivate values to above your rev limit. Mine is at 8500. Otherwise your WGDC is 100%. Bad things could happen at the top of the rev range...

Another thing, re-scale your rpm axis for your boost tables(WGDC/BaselineBoost), to get better resolution/control where you need it. 500/2000/2500/3000/3500/3750/4000/4250/4500/4750/5000/5500/6000/6500/7000/7500, or however you like. Since you have 100% duty cycle till 2500, you could better utilize the 1000/1500/2250/2750 cells. You will have more control over the meaty part of the powerband, rather than spool up. 

"Base Wastegate" (Main and Alt)
"Boost Desired Load" (Main and Alt)
"Boost Desired PSI" (Main and Alt)
"Min Load for Boost Control"
"Accel Enrichment (Incorrect)" This seemed odd.
