The signal is based on pulse width modulation which just controls a vent. The force venting is a function is vacuum system and force from wg. Wg force and turbo characteristics as a function of wg position is significantly changed.

Also issues only shown on speedtech pwg cars as seen in some of my peers here. Same or similar be between pwg and ewg cars

Shoot just check out fmonerios logs!!!! Super smooth

It's getting there. Still have some throttle closures, but nowhere near as bad as before.

The addition of the canister made a significant change, however I cant say its a good or bad one. Now the oscillations are much less sharp with smoother boost curve but longer to correct.

Currently investigating adding a vacuum "pill" and/or seeing if I can use 4/4. I want JB4 for meth and PI control which I am not certain 4/4 will do.

Prior to making any other changes I am going to put a vacuum gauge inline with the WG line and see WTF is happening to WG signal during this period. I am curious what my vacuum is during this transition period. Perhaps there is a change in source vacuum that needs to be addressed.

Yes those are a total headache, there are torque limiters and all sorts of crap going on making it difficult to get load where you want sometimes. Keep playing with tables.

Will keep you guys posted on any notable changes. Picking up vacuum canister today
Don't buy parts. If you are concerned with vacuum system use a vacuum gauge to measure and evaluate it while you're behind the wheel.

Tried so many things and I think I’ve found a winner

In bef reducing spool mode and changing warm in vanos. I tried adding and removing 5% to 2750 at high load. Did this to in and ex warm vanos.

I’ve made 20 or so logs and I am still tweaking. Will update post when dialed in. So far it’s working!!!!

Hope you're on the right path! If what you find turns out to be a trend we'll update our BEF maps to include a hybrid specific map.

Please share an update when you can. I am experiencing a similar issue on my car, even though it is a stock turbo FBO car. Boost curve looks similar where it spikes, drop 2-4 PSI and then recovers. My WGDC also falls below the FF curve when this happens after spool mode.

WOW.... That looks like the exact same thing....WTF. Well its worth a try. Change the in (warm) vanos setting at 2750 and 148 load (Assuming you are PWG) by increasing 5% and blend to lower loads and lower rpm (say 3 cels out). See what it does.

Some part of me feels like this may be fixing a boost control issue with VE adjustments. But then I go look at my MHD logs and i got a spike there also so maybe its car specific.

I will try it once I'm done working with Terry. Going to disable spool mode and see what it does. I can feel the car bleed off power than come back on. Very annoying, shouldn't happen on the stock turbo.

Another log in Map 2 from last night. Same thing.

I hated it, removing spool mode will likely not fix it, it has to do with tip in and appears to be VE related. if you reduce PID it will smooth it out a bit. Its a good idea to work with terry, spool mode helped me for like 3 good logs until FF caught up and PWN and FF kept varying to much.

Vanos changes have been tweaked a bit more, car is smooth and powerful. Here is a example.

Nice! Looks good! I have had some success on my end as well. Glad to see your vanos adjustments are working out well. I took a different route but it seems to be working well for what it is. Car feels MUCH better.

Spool mode disabled:

Boost dip is virtually gone, only drawback is a *slightly* slower spool that I'm sure could be tightened up with more attention.

I may just disable spool mode in the BEF maps by default. And then those who want to put them back on can manually.

wow! I wonder why this is happening on a stock turbo car?

No clue, but luckily we were able to figure it out. I do have an inlet, so that could play a factor compared to most other stock turbo cars. Waiting for my PS2 to ship out this weekend! Hahah.

Interesting.......

One additional theory that might line up here: Inlet and PS2 could reduce the vacuum to control the WG which could change how the solenoid controls the WG. Signs that point to that are that the EWG cars dont seem to have this issue but some PS2 owners do and atleast (2) speedtech PWG customers have this issue. Removal of spool mode helped mine but not enough. Changing vanos settings will change the vacuum as well, i could be just making the JB4 system happy on vacuum. The EWG cars control boost much better from the looks of it.

At the end of the day i am just glad the car is running smooth. The one off boost feel was killing me and drove me away from the JB4. I had the same spike with MHD but it was not as bad.

Theory above could be totally wrong and its just VE like Terry suggested. However VE should be the same for EWG and PWG cars. oh well. All i can do is share my experience here and the platform will learn as it grows,

I hate that feeling of boost drop off then recovery plus I think it's messing with my timing. I've been playing with duty bias tuning for a while now, but nothing seems to work. I want to try disabling spool mode. How do I do that?
