DCT GTS Software Upgrade

"Your shift speeds etc. caused wear and tear not normally associated with regular DCT so unfortunately we will not be able to honor your warranty regarding this 5k repair....??" ??? I'm just saying.....for mildly faster shift speeds that maybe increase the speed of your car barely...is it worth the risk of potentially losing your warranty...??
I am not saying I would not get it...I was not aware of this until recently...I am just playing devils advocate, to try to see the probability of this risk...and if its worth taking.

I think you're over thinking this one. I don't think the BMW techs are that saavy when it comes to this stuff. Everyone decides what's enough risk for them, but DCT seems rather bullet proof and the GTS DCT tune makes a big difference in feel.

I just got my car back from the dealer and they recoded the whole thing. Car felt sluggish with wishy washy clutch engagement. Got reflashed by Alex and my car feels "normal" again. GTS tune improves driveability around town and on the track. I couldn't imagine having DCT without it now.

Hmm, really? Just read this...

Since everything on this car costs 10k+ even the parts...lol..I'll take a sloppy but effective trans, over a voided warranty.
However, that's just me...

The post you link refers to ECU changes. The GTS DCT tune only changes the DCT module not the ECU. Dealer would not even have to plug in a diagnostic tool to determine if the DCT has been modified since with GTS putting the car in gear defaults to D2. We all assess risks differently - sounds like you're risk adverse which is fine. I have the GTS DCT mod and two years left on the warranty and I was willing to take the risk, whatever it might be.

I hear ya...

The risk to reward on these cars is my problem. I have had low cost tuner cars off warranty and highly modified and tracked. However their engines and transmissions are easy to work on and cost like 2 to 3k...

The BMW M3 is a different animal the transmission is what? Like 10K to 12k !! I understand the desire for the quicker more efficient shifts. I want to do it too. However, the risk to reward is not good IMOP....You have to make a conscious decision to (possibly) get denied warrany coverage on one of the most important parts of the warranty - the coverage of the DCT transmission. For slightly faster shifts? Hell, you could get denied on a transmission problem that had nothing to do with the flash, and these DCTs have allot of moving parts just ready to cause problems.

Got Alex to code the 100ms GTS DCT and Euro MDM. He's great guy. I originally had the stock GTS DCT for 2 days and it was awesome but I didn't want to have problems down the road so I turned to him. Very helpful and patient guy. Car is still definitely better than stock DCT! Thanks again Alex!

It's not about faster shifts, it's about a much smoother experience throughout, and yes, it gets rid of that Reverse-1st lag. I wouldn't over worry about it, it's still BMW software.

Thank you guys

But yes, if you are worried about BMW refusing to perform warranty work on the DCT, don't get it. They don't void the warranty, they just don't cover the costs of any repairs associated with the trans. I think that's reasonable.

^this and trust me I've tracked mine on the south florida heat without any issues.

Just had my coding done with Alex@Alpine this weekend remote here in Canada. Really patient! lol. Everything runs as should. And as everyone else is saying the GTS DCT makes a noticeable difference when you're gunning it. Granny-ing around town it's a little more smooth, R to 1 is instant (never really bothered me), but when booting it it's hella fast.

+1 for sure from me

Does the GPS software remove the start -stop feature? I can't seem to get it to do start-up stop anymore.

Just purchased it ... Cant wait for the remote GTS update for my 08 e92 m3

Chris, old thread but curious if you updated your DCT? From what I read it is clear the the US market of some reason have a more slugish tune (incl not D2 default, reverse delay) than we have in EU but wonder what the GTS does in addition.

Tack

+1 for Alex at Alpine

He is just terrific. Friendly, helpful, efficient. What he charges to do this is an extremely good value. We should all support him.

I won't go into the GTS DCT reflash benefits... they are well covered here in earlier posts. Suffice it to say the car is SO much better to drive now, whether cruising or driving at speed... my car is a 50-50 drive/track kind of car, with MPE installed. The reflash makes a big difference in how it runs and how it sounds. EXCELLENT!!!

[lve2xlr8]

Even though I don't use it often, the start/stop feature of the car no longer works after the software change. Is there anyway to implement this feature back into it?

Thanks!

Alex remote tuned my car well I was eating dinner and its has performed flawless since day one. He was also nice enough to make a few recommendations on the fly which I missed during the coding selection process.

Very happy with the overall result and I'm sure you will be as well!

Do you talk to him over the phone while he remotes in?

Hi Alex,

could you please provide some specifics on the differences between this tune and the OEM Euro?
From what I read I can see there from some reasons are differences between
US OEM and Euroe OEM so curious to understand what the additional upside would be?

Thanks

[CDNRay]

Hey Alex, I sent you a pm as well but was hoping you could give me an update or tracking number for my order. Appreciate it and I'm looking forward to getting the tune.

I heard from another coder that because of the ability to shift faster, your car stays hotter and to only do this update if you have another intercooler! I'm not in warranty and the last thing I want is to over heat my engine lol

Have guys noticed anything? I wanted this software update but the coder did not recommend it.

Granted I don't have this tune anymore but I did have it for a few months and I didn't notice any overheating. I always keep an eye on the Temp gauge and it was moving the same way it always did.
