Can't figure out this very high idle oscillation after driving
 

I thought I squashed this but it was doing it again today. After spirited driving (say after an AutoX run) if I put the clutch in when revs are above 3000rpm when coming to a stop the car gets stuck in a cycle of high idle and overrun fuel cut. The issue is shown in the first half of the attached logs. It does it more rarely now, but can someone please give my tune a look at see if there's something I missed thats not right? Thanks!

Had this same issue when I first put the MS in my car. I cant look at your tune while I'm at work, but what fixed it for me was switching the idle control initial value from "last value" to the initial value table, and setting the values in the table myself while sitting in a parking lot. I can send mine to you if you want to look at my idle settings - it hasn't happened to my car since making the switch about a year ago.

That would be great, thanks. I am selling the car and this is the last tune gremlin that I am trying to squash. I would appreciate seeing your tune.

One obvious thing I see is your overrun "and Kpa Lower Than" setting is too close to your idle MAP.
You should be using a MAP just above what occurs when you lift off at speed - your log shows idle is around 28 - 29 Kpa (or there abouts) while lift off at speed is around 18 Kpa.
Your "and Kpa Lower Than" setting is 27 Kpa.

I would recommend using "and Kpa Lower Than" of 22 or 23 Kpa.

My current tune is over here:

With these settings my car starts and idles pretty darn close to OEM, even with the recent turbo install.

Under Engine and Sequential Settings, your Injector Size is 0. No clue what that does or doesn't do to your tune, but mine is set at 788 for the FF injectors.
