What do you mean wouldn't stay in gear? It slipped out in to neutral or it slipped and didn't engage torque converter lock-up?
The reason I ask is that mine slipped fairly bad in D in 1st before giving it a bit of time to adapt. It's been fine ever since.
On changing 1->2, it'd slip out and go back to 1 and revs would skyrocket over 8krpm and it'd throw all kinds of trans codes and fall on its face. I posted a link to a thread describing it better with my logs from the events. It was repeatable, would not stay in gear. No issues with the first discovered alpina flash.
I'm using the Alpina 7603537 trans flash, and my custom TREBILA performance flash tweaked specifically for AT with alpina trans flash, and here is the results in D mode at low pedal input (<50%) , upshifting between 2400 and 2500rpm, as it should be:
higher pedal input will result in higher rpm shiftpoints, of course

was calculated torque already logged under wgdc in your log ?
real overboost to 21 psi (no throttle closure) during upshift from 1st to 2nd is scary for your trans.
not surprised it can't handle this torque.
FUD = 99 (no wastegate adaptation) may not help.
there is something wrong in your tune. you should get throttle closure to avoid overboost.
update your JB4 firmware and interface, then fix your overboost issue, and try again with the recently found alpina trans flash.
Those logs were old and just an example. It would also come out of gear when not trying to change. That coding was just bad news on my car. maybe due to some x drive weirdness or something, dunno. It's happy with the original alpina flash.
The BMW 2011 flash seems to be the sweet spot on my N55 X1.
All of the other Alpina/Sport softwares made my transmission feel like it was broken. Terrible part-throttle shifts in all modes, shift flare when upshifting, etc. The Alpina software was brutal and shifted awesome on the track, but it was just rough on my commute to work and didn't seem good for the transmission.
The 2011 flash is a peach in "D" mode around down, while still lowering the shift points a little for better economy. It's not sporty, but it's smooth, and not embarrassing with passengers in the car.
In S or M mode, the shifts are faster, but not harsh like the Alpina SW. It's a nice quick "bump" into gear on upshifts, not a slam. Stock software was mushy in S/M, but the 2011 SW seems to have cleared that up.

Teach me your ways, the Aplina D mode is trash. I've tried 1494, 5835, and 3537 and they each their own strengths and weaknesses. I'd prefer 5835 with a higher shift point in D. Your video would be ideal actually.
So, I've expressed displeasure in the Alpina trans flash, and pretty much every trans flash on my X1. They just felt clunky and confused a lot of the time.
I accidentally reset trans adaptations a few weeks ago, so I reflashed it with the "New" Alpina flash for kicks. Took it out last night and ran it through the gears slowly, gradually increasing throttle application with each run to let it adapt. It is hugely improved over what it used to be now after letting it adapt for an hour in various kickdown/upshift scenarios. Will monitor as time goes on but I think this was a great way to fix the issues I was having with the Alpina flash.
Note that resetting adaptations apparently requires the exact BMW method of re-learning it, which I still don't have and am not happy about, so do this at your own risk. Would love to have the proper procedure so I can relearn it "by the book" at some point.

It would be a lovely thing if we could find a way to disable adaptations. I feel the trans with any of the flashes does wonderfully until it learns adaptations.

That is a great PDF there! Random question: On page 50 it shows them inserting something to evacuate the torque converter. Do you think they're pumping in air in order to force out the converter fluid?
Do the Tool32 adaptation resets work on the transmission? Or are they engine only?
That is awesome, I printed out the "Software T" adaptation process on page 43. Thanks!!
RE: Adaptations
You should be able to do it in INPA under the GS19 transmission menu.
You're welcome !!

I'm not sure what they are doing...
Yes, those adaptation reset jobs are specific to the transmission. From Tool32, open C:\EDIABAS\ECU\GS19D.PRG.
Alpina B3 Flash/BMS OCC/ER CP/ETS 5/HKS BOV/M3 Control Arms/OFT
Okay so what i getting out of all this is that The New B3 is basically the best for all modes except D in which case is shifts too early? Which for me isn't too bad of an issue being that 80% of my driving is highway cruising?
If anyone cares, Wedge posted this on e90post regarding many of the flashes people have been trying:
Quote:
ZB # are incremental, and larger numbers are the newer files. 7615835 is the last Alpina B3s transmission flash that was released and has a direct impact on torque limiters. The Alpina flash is listed as an E90 N54B30ATL ECE flash and was released in 2010. It is the most recent N54 AT specific transmission flash that has been released for the GS19.11.0 transmission, again this is specific to the N54.
All of the 760xxxx files were done in 2009.
There are two older flashes you can try. 7603537 and 7603535... Both are E90 N54B30ATL ECE flashes.
7603527 is a flash for the E82 N54B30ATL and release in 2009, so I'm not sure how anyone made the assumption it was a 2011 sport flash.
7603541 is from an E89 N52B30OL. Not even an N54 transmission flash.
7601494 is also an E89 N52B30OL. Still not an N54 transmission flash.
There are a lot of GKE215 ZB#'s you can play with. Not all were designed for making the power our cars make. I have to laugh when people without any knowledge of what they are talking about release old ZB#s as newer numbers as if they found something new. Depending on the power you are making, chances are you'll have torque limiters in higher gears or your clutch pack will slip because the line pressure isn't high enough.
For what its worth, I tried 7601494 and while D mode was great, M mode was slow and mushy, very similar to stock. I put about 15 miles on it at full temp hoping it would adapt but never did.
I went back the the OG Alpina 7615835 and love it, despite the D mode. I use M mode most of the time anyways. According to Wedge, 7615835 is the latest Alpina flash even though we were calling the other one the "New Alpina".

What are you guys using to do all these different types of flashes, and where do you get the code for the different flashes, such as the alpina B3, sorry if the questions seem dumb or pointless I am just very confused by flash. Any info would be helpful.

The flashes come as part of the SP-daten file which contains settings, data, etc. for many different BMW models. There's dozens if not hundreds of transmission flashes to choose from, but only a handful have been tried. It would not be wise to try flashes at random since most are probably not even meant for your transmission. Also, each time to use WinkFP, there is a risk of something going wrong and bricking the TCU.
So iv been running the us sport flash for about 2 months. I love it. Then i went back to the newest alpina. Car shifted hard didnt like it. Im going back to us sport. My car likes it. Im also going to work with trebila and try his alpina fix. Ill update.
