Rich spike after WOT
Here’s my problem:
As you see every time I let on the gas AFR goes pig rich. To around 9-10:1 and then it takes half second when it goes to full lean as it should.
That extra fuel is messing up my LC-1 almost every time. I have to startup whole car just to get my LC-1 reading right again
Is there way to solve this?
Here's my .ecu file

Who did your predicted map settings? Also is the big rich dip present on all rpms/throttle smash %s?
If so you can try adding 5 or 10 to the asynch gain %
Your LC 1 is getting maxed out on the lower limit. i believe 9.4afr is that lower limit.
Too much fuel will cause the car to buckle up when you shift.

didn't help.
I also downgraded to 1.00a and well it’s seems to work better but it still lock down every time I hit rich cells (=AFR gets lover than 10:1)

How did you do the predicted map settings? That matters a lot. I was having the same issue, currently my settings seem to be good enough to when i smash on the throttle the a/f doesnt get bellow 11.5 even on big stomps. I find it easier to have a passenger look at the boost gauge. Simply get the feel of "15%" and give it a stomp. Then get a feel of 50% and then same thing looking at the boost gauge. At 100% throttle you should be at your max kpa your wastegate is set at however this is the initial stomp so due to turbo lag you're not going to be up there at full boost yet. Thats the reason why you're getting rich. The adaptronic manual tells u to get the rpm to where it needs to be and hold the throttle at that % and then find the kpa. Not really right as at that point the turbo is spooled and steady. You want to find the kpa the instant you stomp on the gas with the lag taken into account.
Also you want to lower your 0% at +4k to 25kpa or so, otherwise you'll get a rich spike after letting go of the gas. In reality 6k at 0% is impossible so you'll only hit that cell when you let go of the gas.
Another thing i noticed is you are pushing 2 psi at 1k rpm the instant you stomp on the throttle. Doesnt seem right. Again your predicted map doesnt seem to have the lag in it as the reason for your issues.
