I adjusted my cruise areas to be closer to 14.1:1. X is 40% into boost (35% from a stop seems to work better) and Tau is 0.400. It felt a little better but still a hiccup in power when there's a large delta in TPS. See 62s and 83s to see 25-30% change in throttle.
Cold weather shows I could use some more fuel into boost!
I agree I think you may need to richen the fuel map between 3-4k rpm and 0-15psi boost. If it ends up being too much at steady state its easier for closed loop to remove fuel rather than make up for the lack of enrichment. You could also try increasing X or Tau further and see if that helps. I'd be interested in seeing your results.
I would say I probably have the most experience specifically with the adaptronic on this tuning formula. With that being said I will do a write up this week on it for everyone.

I do apologize that I have not written the guide yet. There has been some major changes in my life and its just going to delay the guide about a week. The guide will be on a separate website than the forum as I can ensure the quality of the guide. I know some of you will take this the wrong way but I promise the guide will be available to the public and it is not just a regurgitation of Andy's explanation of the transient solution aka fuel film model. I will have a in-depth guide on the tools that are used to obtain your X, Tau, Transition time for Map Prediction, Predicted Map table. The the tools that are used are both Adaptronic tools and a 3rd party application.
Thank you for your patience
Cheers,
Shawn Christenson

Any update on this guide that you stated you would be providing? Its been a month and a half and the only update we got was that it was "going to be vague".
Yes as I stated before there was some major changes that happened in my life. I do still plan on making the guide - Could possibly be done this week but that is not guaranteed.
For me main problem with AE on FD basemap was MAP prediction not activating aggressively enough.
YMMV, but after a lot of logging TPS rates vs TPS position and predicted MAP vs actual MAP I started changing the Sensitivity %/Sec to lower values for cells so that AE and MAP prediction actually gets activated when it's required.

This is right on par with my experience with the PMAP tuning. It just always requires a good ol'e fashion fiddlin with to figure out what works for each car. I had initially tried to figure it out mathematically through log data to balance the PMAP points with the transition time and the actual boost level at the transition but I ultimately found the seat-of-the-pants feeling of the car responding to a throttle change was really the best gauge on the PMAP settings.

I'm also stuck on the same boat with the transient throttle stuff. It was tuned and it runs amazing and pulls hard but at certain conditions (ie. quick throttle changes during a mountain pass/touge, cruising at 4k at 100kph and applying throttle) it will feel like no response at all, like pedal to the floor and nothing happening. Wish there were more people with our setup to see more results/setups that work with it. I'm running 1050x Primaries and 2000xx secondaries.

Im having the same issue, tried 40% pooling, 0.4 evap time with 0 async. Tried also acceleration enrichement tables with no success. Still have a lean spot after i blip the throttle

any updates here?
Are you just talking about in the datalog or you can feel it hesitate? Have you setup predicted map table and tps sensitivity? Xtau can't fix what it doesn't know about.

I feel it hesitate and afr go to 22 just after i blip throttle just as described in op
i ajusted map prediction table using mlvhd with a large cruising log in a graph using tps vs rpm vs map
my fuel table is aslo tuned, when i check it with the tracer, all the cells in cruise zone are fine
i checked with logs and i see the tps go up, then map go up, then injector duration go up then down and when it goes down so does the afrs
i tried with x and tau tables, async table, ae manual tables and they all give the same results
Make sure your throttle enrichment and Map prediction actually activates. The are flags you can check for this but plot map and predicted map on top of each other and check.

Adjust sensitivity in throttle %/%
This was one of my problems when I first started. Reference the the modular S6 basemap values and make sure you see AE triggered when you make a moderate (coming off the clutch from a stop) throttle change. If I recall, my settings were not sensitive enough and normal throttle movements wouldn't trigger any AE.
What I've been fighting is the opposite of Mad666Max, my AFRs go too rich but I may have tracked down the problem. I thought I had ASync disabled, but it is turned on and set to values like 60, 80 and 100%. Does anyone have a map they can post with reasonable AE response with Async enabled? I will double back if I get a chance to test some changes.
So i figured tps rate to trigger enrichement table values need lower values to make it more sensitive. Played with that and seem to be better but now i get a rich afr 1-2 seconds after i blip throttle.
i lowered x/tau with no success, must be the tps rate table thats too low now but not sure

Hey mate, in the datalog you pm'd me you weren't triggering predicted map, as you realised above. My car hasn't been running for a long time, but from memory the attached values worked ok for me.
