I feel like I drive pretty hard on the streets and i don't really know about how 'Raw' the f80 is. It definitely feels sportier and dialed in than what I was driving before but I can't really say it's anything insane as of yet tbh.

No other qualms about the vehicle from me. The e92 I drove for a bit on vacation felt more 'raw' if that makes sense

My observations are that a lot of e9x owners feel they enjoy them for aggressive street driving when given the choice between the f8x and the e9x.

The f8x will come to life more on the track. That said, the dct on the e9x is a rougher experience than the refined version on these cars if I have read properly.

I'd suggest getting driving shoes, Puma has lots of options for a decent price. Then good seating position and whenever you're in Sport+ keep thinking how gas pedal travel is dramatically decreased, boost is built faster etc, best said engine response is without filters. Whatever is happening with the car is because of your right foot.

I'd also avoid driving in Sport+ and DCT in D mode. If you wanna go fast and feel connected DCT should be in S or manual mode. Driving in Sport would be much better option for getting familiar with it before doing any software updates, replacing mechanical parts or ending up saying how this car sucks and getting G82

I agree with that sentiment to an extent. Anyway, for me regardless of the GTS flash availability or not, I love the car already and it's only been 7 days. The experience can only get better from here!

I do agree with the sentiment above that you should take sometime to learn the car and get used to it as is - it'll make the flashes more impactful and you'll utilize them more meaningfully. Also, to level-set expectations, these flashes don't give you a completely new car; they take an already great foundation and add the 5% of extra magic that really unlocks the car in stock form.

A note on CS damping as part of the package, it will be a noticeable improvement to the ZCP damping however, it is designed to be paired with the base (non-ZCP) sway bar. On the street you won't really notice it but if you drive in a performance setting you'll get a tad more understeer than you otherwise would have if you had the correct sway bar.

Are you able to elaborate more on this line for the GTS Tune?
"Also changes the tone of your exhaust to sound sportier and deeper on stock untuned engine." Did you experience a sound difference? I am not sure how a transmission tune affects the engine note LOL.

Why not ask the person that would do the coding or check the bmw software differences?
They just install bmw software so it's not a custom update.

On my old car I honestly didn’t notice a difference in sound, didn’t realize that was part of the package lol - I ran (and still am on the F80) an EL mid so it sounded great to my ears either way.

Big discussion and do know I have worked to eliminate this bucking that initially seems to be foot related, but do think there is more of an intervention in the traction management that is excessive in certain modes. In short, if you put just your TOE on the throttle, move the seat way back (essentially trying to eliminate any foot/body interface), my M3 bronco is still there, most notably, when just trying to push away from a stop 'mildly' aggressive. Using just my toe really reduces the body language part of the equation, but there is a noticeable intervention that begins the bucking just off the line that is not my toe doing anything. Case in point, anything past half throttle is no problemo. So a simple question for all M3 bucking Bronco owners, does it do it when you use the launch feature????

I have a 2015 without any flash or upgrade from the dealership. I just learned to drive the car and use the pedals.

Also don't floor it off a stop.

Is this the same as the GTS flash in bm3?

2015 here. I did get the GTS flash but this is mostly a driver error issue. You have to learn to roll onto the throttle or you'll get the bucking bronco. If it starts to happen, shift to second and it will stop. Also driving in manual mode all the time helps quite a bit. Can't remember the last time I drove in "auto".

For the record this is like the 1000th post on this topic.

so I got the gts flash on tuesday. what i've noticed is that the accelerator feels 'heavier' per se. I also switched only the engine from sport+ -> sport and that also reduces some of the kangarooing. as for flooring it from a stop, I can't not do that unfortunately as that is a pretty big chunk of having fun with these cars haha. I think I'm getting better at avoiding this issue though

The car has character...
Lot's of it. You'll learn it's quirks in time and love it.

I only had this issue in Sport+. There was a suggestion, a long time ago, in another thread, to have all of your foot in contact with the pedal, with the heal at the pedal pivot point. This worked the best for me.
