I would rather break it in to save problems from arising...just my 2 cents

Hey Guys,
Just picked up my White 2012 335is DCT Coupe last week. I am doing the stage 2 Dinan software upgrade to the car but.... should I wait to the so called break in (2000Km) to install it or just install it right away?.... Thoughts

Yes wait for the break in period to pass first before flashing to Dinan S2.

Did most of the 335is owners/you follow the manual and not drive over the 4500 RPM for the break in period?

[Edward]

I broke mine in properly. My last 3 series I didnt break in at all and it was fine.

Good thing is that there's plenty of fun to be had to 4500 rpm.

Do any of you know how long after the initial 7 sec torque burst that the car will allow for another? Is it after a certain amount of time, range of driving or something else? I haven't experimented enough to try to figure it out.

i believe it goes by distance

Overboost doesn't form with my car nomore. JB4 took over EVERYTHING LOL! But I do notice when you do launch control with DCT It seems to ratio the gears and shifts like 1k before red limiter. I like how it adjusts to it's own when using LC. When I run my car hard shifting at 6.5k It shifts rough exactly like how SMG hits you with setting on 5.

Hows your car btw? I'm not sure if its me or not but does your boost seem to drop after like 130+? It's like the lining drop the boost down to protect the tranny from being damage by soo much boost. When I hit it from 60 it does around 16psi but when it gets to around 130+ I get a nudge from the car and it drops it down to 10-11psi. Not sure if it's just me or not. I have every bolt-ons besides Meth and R&B turbos.

Aren't you worried about damaging your DCT with a tune? I thought I read about DCT slipping because of a tune.

Actually no...I worked on breaking in first and second gears prior to 1200k and I pinned the speedometer multiple times.

You have to feel out the car, if it becomes jumpy then its time for WOT, if not, then just be casual.

It all depends on the temps if the DME will allow it or not

Taking mine in for 15k mile svc. Got a question for those with DCT. When your gear selector is clicked to the left for manual mode and you press the P to park, does it click back over automatically? I thought I remember mine doing this but now it clicks like its TRYING to move the selector over and I get an (orange) error on my dash.

This rumor has been the most twisted out of context rumor I have heard. Not blaming you, but you know how rumors travel especially when its online

All authority in the matter have reported the reason for the slippage was from pre-existing abuse on those clutches

Here are the main referenced authorities "in their context about slippage":

But rather a consequence of those several drag strip launches I did last year when running hoosier slicks where it would routinely trigger transmission over-temp warnings/limps. From that day onwards, our 7DCT would slip in the 2500-2700rpm range if we ran more than 13-14psi of boost on dyno. So I'd say that the clutches in our gearbox need to be replaced/upgraded from the abuse.

So the (DCT) transmission is weak?

No, not at all. Actually, it took far more than anyone would have thought. At these drag events, I would also run back to back at times. Keep in mind, I bumped the launch control RPM up as high as it would go, 6200 RPM. These are 6200 RPM launches after a burnout again and again. I estimate 70-80 uses and a properly used manual clutch in comparison should be good for about 50 passes before needing to be replaced. Just to give an idea of the abuse I put it through, I needed new motor mounts a year in as the abuse in the launches took its toll. Oops


.......The unit BMW uses for the M3 is the Getrag 7DCI600. They rate it up to 440 pound-feet and 9000 RPM which is actually even a bit conservative. My transmission took about this torque level without incident driving around. It is the launches and overheats which made it so the clutch packs started slipping. It never fully gave out just the clutch packs were starting to slip and it was not going to get any better especially as I strove to add more power. If launches and drag strip visits are removed from the equation, on the street with a supercharger, absolutely no issues, just like stock. One can even exceed the recommended 440 pound-foot limit if just using it on the street like a normal person.

DCT Build Part XII (Google it, website not allowed to post)

If you didnt know, the DCT in the 335is is the exact same DCT in the above mentioned M3.

Slippage on DCT can even occure with the stock tune if you apply too much throttle or you go WOT from a stand still to fast.

Everything depend on the condition of your clutches and how you are applying the power.

[FoShizzle]

Good info above. I remember following those threads. I don't spend much time on the boards these days but I do recall reading that the DCT in the 335is nearly the same as the M3, but is rated for less torque. (different getrag #)

Convenience Package (comfort access, park distance control, power rear sunshade)
Premium Package (auto dim mirrors, compass, garage door opener, lumbar)
Heated front seats

I watched probably several hundred youtube videos showing the car and exhaust sounds. Read every review online. Can't wait for the car to come in.

Will be sad to see the 2008 335i 6MT go, love it to this day, and the Dinan stage 2 had been great.

Where to get a good quality set of amber reflector replacement in dark smoked reflector type? Not the painted ones, but the smoked ones?

I have the EXACT car. I will be posting pics after my mods are complete. But I'm in love. You'll be very happy. Congrats

So if the temp is not too hot it will give you 7 sec overboost on every WOT or is there still a certain amount of time or range of driving you need? I've been looking for this info and can't find anything on it.

Thanks for sheding light on this, very informative. I didn't even know our DCT was the same as the M3. I guess it just doesn't have all the extra settings and such? This now makes me want to get a tune. I thought Cobb was coming out with an AccessPORT for the "is" but I don't see anything on their site.

Yes it does

DW man im in your same situation. with the press P buttin and it trips out trying to push it back and pops up a code. and sometimes has a lag to it n shit. I thought I was alone in this haha.

The overboost option to be honest I didnt pay attention other than I didnt see 14 PSI unless using LC. When the checker flag is up overboost was available. I cannot confirm if overboost is available on regular WOT runs

Since I dont have a M3 DCT to make the comparison, then I would say I dont really know. However I do know the LC on the M3 DCT is more robust but on the 335is it is more flexable to launch the car in the RPM range to a MT

BMW was thorough in revealing how to use LC on the M3 however they did a poor job on the 335is. There is soo many hidden ways to use LC on the 335is its a joke.
