I finally ponied up the $270 for a BMW ZF6 auto transmission tune for my E84 X1 with the N55 from XHP Tuning.
Let me first say, I really like this car, it’s quick, just right sized, practical, and gets not completely terrible mileage. I suspect when I get better tires I will feel even more positively about it.
The ZF6 auto isn’t bad, but in D it’s a little clunky(shift speed and firmness are inconsistent), it’s default to start from a stop is 2nd gear, and manual mode is not a full control proposition(though much better than many I’ve tried).
The XHP Flash and specifically their Stage 3 map is a really good move in the right direction based on my first drive with it. It has the car start in first from a standstill, it’s more consistent in shift firmness and quickness in D mode, and manual mode improves shift speed quite a bit and feels more fun and with more left up to the driver. All in all it seems well worth the money.

As much as I dislike new cars, and I do. It’s pretty cool to just be like “beep boop” faster!
Tuned my alltrack and and it’s a much better drive now.

Very nice inline six tall wagon. The new X1 is so uninteresting in comparison :(

Yeah, this was a small cost for the amount of improvement. 2 minutes and all of a sudden my transmission is not far off from some of the better current ones.

Thanks; I do enjoy it. Would at some point like to make it slightly less tall.

I’m really digging everybody posting up their mods. Nicely done , have you looked at an intercooler? I haven't found a single tuned car that doesn't massively benefit from one and reliability is one benefit that is overlooked frequently.

Well this transmission tune was my first mod; when I get around to an ecu tune, I will replace with a larger FMIC.
I’m looking to do: tires, then Bilstein lowering kit, then ecu tune/fmic and intake.
