Auto mode: (normal driving)
1- Change into 3rd gear has become slower than stock
2- Change into Reverse is faster, Change back to Drive is the same as stock.
3- Rev matches down to 2nd and 1st gear more often..feels a bit too often.

Manual mode: (spirited driving)
4- definitely more aggressive and noticeable faster upshifts under load. It's fantastic!

My question is, if there is a gain somewhere (in this case aggressive upshifts), is it normal to have some kind of loss elsewhere? (ie points 1 and 3 above)

Any comments or updates on these negative (1 and 3) issues noticed?

DCT GTS >>> Stock DCT
It's a no brainer.

Alex @ Alpine is awesome!

GTS DCT flash is excellent. Best mod for the money, IMO. I would never go back to stock SW.

I'm going to be giving Alex a call monday

This.

It has been suggested repeatedly that most of these DCT flashes are just modified versions of the GTS software. Each vendor has their own specific adjustments, namely to not be quite as aggressive as the GTS.

Question, when this is brought to the dealer is there a chance they overwrite the GTS flash?

PS, just purchased today and really looking forward to it! Can't stand the low gear lag...drives me nuts!

There wouldn't be much reason for them to overwrite the transmission control module. Sure they have the capability to do so, but why would they?

I've had mine in for service several times and never had an issue. Even when they were trying to tell me that a noise I was hearing was "inside the transmission" they never touched the software side of it.

In short, yes.
When a car's integration level is upgraded (programmed) by the dealer, by default it will update everything that has an update available.
As for when the last DCT software was released, i dont have that info but i can dig up my E82 DCT programming logs to give you guys a rough indication

I installed the OEM GTS software last weekend at the track. It is a night and day difference

I much prefer it on the street as well. D1 is very well judged, more comfortable than the D3 I used on the street before

So I had Alex code my car and loved it all. the tune, the options like folding mirrors, etc.

However, I now have an issue with my DCT.

First let me clarify, this is not putting Alex's coding into question. My friend has had his car coded for 6 months zero issues. What I'm trying to do is see if anyone can help troubleshoot this issue or have had similar problems.

Essentially, Ive had the tune for about 3 weeks and loved it and worked perfectly. All of a sudden, intermittently, when I put my car from Neutral or Park to D1 or Reverse, the clutch engages (without any throttle) and lunges my car forward and back and then stalls. Its intermittent so I dont know when it will happen.

My friend whos a master tech at BMW has gone through the normal troubleshooting and diagnostics and came up with this:

Transmission overheat Fault, clutch one pressure fault.
Transmission was at 70 C
Hydraulic Pump 160 C

which makes no sense to him, so he had BMW NA Pull Shadow Codes and Diagnostics

and their diagnosis was the clutch may be worn.

But my Tech ultimately thinks its the GTS tune causing the problem....thooughts?

Flash the stock tune and find out?

This guy seemed to have similar issues after GTS tune. Might be worth to read into.

Is the dinan dct tune any different from what alex is offering?

I doubt it.

I had Alex do the GTS DCT tune + other stuff last night, super nice guy and great price. Would 100% recommend him to anyone interested.

The DCT tune is amazing, I can't believe how bad the factory tune was after driving around for only a day on the update. So much smoother rolling from a standstill through first gear in traffic, much cleaner shifts when cold (2nd through 3rd), and being able to go straight into D mode is a nice touch.

Same here, actually think he was coding both our cars at the same time.

Great value on the coding and dct tune. Well worth it.

The awful first gear clutch slip is gone and downshift are much cleaner and quicker.

None of you guys worry about the extra strain and heat from the GTS flash? I know the GTS has a cooler.

[4130]

I've had it with zero issues for almost a year. Many people on the forum have had it far longer and have tracked with it in hot climates without issue. I figured if I hadn't read anything negative in the few years it's been out then it's safe. Additionally, I had read that the shift time is slightly tweaked by Alex to compensate for the lack of extra cooling.

Nope. Zero Fs given. The car operates like garbez without the GTS DCT update, to the point where it feels like a mistake.
