Here are my most recent logs. Rev18&19 Logs are on the 17.40 PSI combo. Rev20 and Rev20_MAPVacuumSource are on 15.95PSI. The latter of the two is with the boost reference on the charge pipe location, the 3 bar sensor right by the throttlebody (TIP sensor I believe?) that is shown in the pictures above. Rev20_ChargePipe3BarVacuum_14_50PSI is on the 14.50 PSI combo, as the name denotes. I am still not the best at looking at logs, but am trying to learn. Any comments anyone wants to make, feel free.
From what i can see in your logs it looks like the 17.4psi combo is opening around 220+ish kpa but only very briefly. . like your just barely tickling the springs open and then it shuts right away.
With the 15.95 combo it seems to be opening on around 215ish kpa and staying open until 5200+ rpm. . . Which does seem to be a little too long to me. Is this what you meant when you say it's hanging open?
This of course is my interpretation from what i exprienced after using the wastegate mod myself and of course every car will respond differently.I would imagine brad has given you more experienced and in depth interpretation of your logs so doubt this is news to you but that's what i'm seeing.
For me it's harder to hear the gate open over the engine's rpm's(or maybe i'm not listening as hard anymore after verifying the mod is working properly for me) but when i let off the throttle during the spike i can ALWAYS hear in snap shut . . might be something to try if you're second guessing the gate opening or not.
Here are my logs before and after the mod-rev 12 10.19. -notice the MAP jump to 220 or more on the 2-3 shift til the throttle brings it back down.
And after the mod-E20 rev4 12.4 -you can see when the gate opens around 205-210kpa and stay in that range til around 4800rpm or so. My car doesn't spike so bad on the 1-2 shift so it doesn't always open.
