Are all GTS tune the same?

I have just tried 7847869 and I'm not 100% sure it is actually Euro DCT Tune because Australian Spec M3 comes with 7847868 (latest update) and it starts in D2 (similar to GTS & CRT DCT Tune) however 7847869 starts in S3 for some reasons.

I don't understand the noise difference as well between 7847869 and 7848442 as they sound the same to me (although some of you believe the noise from 7847869 is more mechanical and rewarding to hear).

I believe 7848442 is less clunky out of all the DCT Tune and rev match better.

When I had the alpine gts tune, I started at D1, not D2...how come?

A big improvement over the US software which is just shit but I feel like it's still slower than the GTS/CRT software.

My car is insanely loud right now so if there's any added drama right now I am unable to detect it.

Will probably move to the CRT software over the weekend as this is a track car. If I had an E93 M car for sure I'd run the '69' software on it though!

Thank you for documenting this! There is SO little information out there on specifics of what they do!

Haha...when the car gets too loud you have to get over the paranoia of noises = breaking. After every rattle, click, pop, grind or whine, I used to say " what's that?"...and I said that about 20 times per lap. Now I just don't care and drive the damned thing.

The loudness comes from headers+an unresonated uncatted xpipe... it is SO loud

It's different to the noises you hear in stripped out cars!

A little clunkier coming to stops as well, but for me, the shifting sound is worth it. I tried to record it but a mic doesn't pick it up too well.

I just hope that I've thrown in enough searchable terms for someone else looking to flash their E90 E92 E93 E9x M3 DCT transmission. Getrag 7DCI600 trans flash faster shift speed smoother operation alpina B3.

Shadow, when flashing my transmission, I have enable UIF / VIN for the flashing, and my "you can still flash the module X more times" counter is continuing to get lower. I believe I'm at 7 right now. Do you know what happens when it hits zero?

Installed 442 last night and went for a drive today, it feels better for sure, faster and 'tigher'

Do you mean ...442?

I should probably start this as its own thread but my brief notes

All ZBs are for the module GS40

ZB 7845773 - This is supposedly what shipped with the GTS.
-Smoother and smarter transmission settings in general.
- S1-S3 do not blip downshifts, they slip downshifts. For this reason I use S4 for most driving.
-S6 will ease into upshifts when around quarter throttle or less, no shift shock, stock US / Euro would upset the car a lot if you did this.
-S4-S6 slam into upshifts, absolutely no cut of power, will really spin from a 1-2 gear shift, 2-3 will sometimes spin even on a hot day.
-Been a minute but I believe launch control was like 3500-4500. Hooked up much better than the stock tune, which just spins tires.
-Sounds (exhaust note) like a torque converter automatic, meshing into upshifts.

ZB 7848442 - Updated GTS?
- Currently using this, very much the same, a minor upgrade
- Can say with certainty that launch control is at 4500, hooks much better than the 5500 launch
- Perhaps a bit smoother at low speeds, equally violent when pushed.

ZB 7847869 - Up to date Euro Flash?
- Smoother than US, faster to reverse
- Better at low speeds than US but still noticeably clunkier than GTS
- Interesting note: The best sounding transmission tune.
-----Gives a really, really nice overrun sound when doing 1-2s and 2-3s at lower speeds.
-----Clear, audible cut of power during some shifts in higher settings, sounds mechanical & satisfying, like racking a gun. Hard to explain.
-5500RPM launch, not very useful. pure entertainment, theater.
- I switch to this when tracking and would use it all the time if it was as intelligent at slipping the clutch as GTS when operating at low speeds.

ZB - 7847868 Current US tune???
- No notable characteristics. Felt very much like when I got the car, which came flashed with DME & trans with 2013 SPDaten flashes. Felt like many of the other stock M3s I've driven. Not bad, but could be better.

Taking the time to type this up because I was frustrated with the lack of notes on characteristics and ZB numbers for all of these flashes. Hopefully someone searching in the future will find this and know where to go.

I would spend your money on getting someone to do Euro MDM, because using those programs is more complicated. American MDM is legitimately no fun at all.

great info there. Here are my flashing steps for anyone that wants to do it themselves: https://www.m3post.com/forums/showpo...1&postcount=11

that would suggest 869 is a US tune. my stock before I flashed 442 was 7642021 and that also started in D2 same as 442, so both must be EU spec and 868 must be euro equivalent of 869.

I can confirm it starts in S3. What about the 5500 launch though? I wonder if we can source some BMW technicals about any of these ZB#s.

Hopefully it goes without saying that these are just my notes on what I’ve tried. the GTS / CRT tunes are certainly the highest performance, but I’m just noting that I find 69 good enough and can attest that it sounds a bit better. Some of the performance can come down to cleared adaptations after flashing, some can come down to user preference, etc. Some of it is certainly placebo.

Can anyone who works with INPA / WinKFP post their ZBs in their UIF if they get the chance? I suppose that anyone that knows how to do this would have already flashed a new tune though.

You guys have some of that brake to slow speed, but not stop, and then step on the gas, and get... NOTHING for a couple seconds and then is launches forward after frantically stepping on the gas. It's not as bad as the original US version, but I still have some of it with the GTS tune (not sure which one I have).

Yes, some are better than others about this. I think that 69 is very good at on-throttle downshifts.

Isn't the Getrag 7DCI600 the same transmission used in the F8x? What do they have? I think they have the same trans pan, that's why I ask.

Ahh fair enough, I think I'll go back to 442 when I have the time and do clutch adaptation.

Just flashed 7845773 on my latest m3, great DCT tune for the street and the track. On my last car with the OE DCT Cooler I ran S6 at COTA for 3 days straight using this tune and no issues at all. Looking forward to trying it at the track again with my current car. Have the do88 cooler on this one.

[barryaster]

Hello all,
Does anyone know how can I know the compatible SW versions to update my car to GTS transmission? It's a European E92 M3 from 2008.
Thank you in advance!

I'm going to revive this thread a bit. I have a dct in my '08 and I bought it with some type of dct tune already installed, not sure what tune it actually is though (or from which company). It starts in D2 and launch control is 3500 if my memory is right. My biggest problem with it, which has begun to annoy me more and more, is that medium-high rpm shifts at moderate to full throttle are extremely hard and really slam you back. My car will break loose on 1-2 and chirp on 2-3 and the slamming shifts are fun sometimes but only in a straight line. However, because of this the shifts can really make the car unsettled when shifting on turns (say if I'm on a long turn on the highway or changing lanes to pass someone). Does everyone else experience this with their dct tune?

The 7847869 (possibly up to date Euro flash) tune mentioned by chocstraw sounds like the only one that might not have these hard shift, unless I'm not understanding that correctly. It sounds appealing but how would I go about getting that specific dct tune?

All of them do that, some are better about it though. Most are good about mid-turn shifts though. You can try calling around for shops and ask if they have the program "WinKFP", and most up-to-date versions will have all the files you need for this. If anyone directly involved with maintenance can chime in, that'd be great, but this is the factory program used for loading modules and the data files include all the modules and several revisions of the firmware.

All of them interact differently depending on the engine firmware version too, it's good to have roughly similar release dates for the trans, engine, and traction firmwares. Consider checking the hardware for issues too, make sure the pan isn't leaking too bad, fluid level is ok, consider changing it if it's original or 50-60k miles old.

I have a DCT tune on my North American car, goes to D2 on first shift and has a 3500rpm launch control. I'd like to raise the launch to 5500rpm but retain the first shift to D2. Can anyone confirm that 7847869 is the correct code for this tune?

Do any of the newer tunes bring back auto engine start stop? I want it on some long distance commutes but lost it when I flashed GTS tune 4 years ago.

Whoa I hadn’t put it together before but this does disable auto start stop. I’ve only put it on when in terrible traffic and it just restarts the engine and kicks you into neutral.

-42 is the one I’m on.

Damn, I need to check but I was hoping 42 would keep ASS. Can you triple check that the A off button isn't lit up on your dash? Please.

Flashed 7848442 (updated GTS) and it is much smoother than 773 (GTS tune), especially during slowing down and downshifts, I'd say everyone should give it try.
