Anybody have extra revs with DCT ECU mod?

With most chiptuning you get extra revs with the MT.
From 8300 to 8600.

My tuner (here in Europe) tells me it's not yet possible to get extra revs for DCT.

We uploaded the some MT ecu 'parts' in my ecu and all hell broke lose!
Stalling, delayed shifting error on the dispay loss of power, safemode...ect.

It's caused by the software of the DCT giving error because the revs are to high..

Right now I have a sickass program in my ECU from BMW Motorsport...max revs 8300

I WAT MY 300 EXTRA REVS!!!!!!!!!..(or more) Any tuners out there who have done it for DCT?
Then I can give my arrogant tuner hell and make him work on it!

Why do you want them? No offense, just asking. The engine makes peak HP at 8000rpm, so why do you want to wait to shift until 8600? That will just slow you down.

Wow, replacing parts of the M-DCT software with MT software? Talk about brave and risky... Engine and transmission functions get completely intertwined in an automated manual. I wouldn't screw around like this at all. Good luck.

The power keeps going up with more RPM...check the power curve.... and less RPM drop.



The MT car have it so why not the DCT??

I know. But we only got the special motorsports program from the BMW engineer for the MT.

So we had to. It works fine, exept we had to lower the max revs. But we're working on it.

Somebody has to do the development.

So? Being able to stay in a lower gear longer adds a lot more thrust to the ground. You will be able to go faster.

Raising the redline is not a big deal, any chip tuner can do it. The advantage is in not hitting the limiter as easily, gives you some leeway.

Sure, I agree, you could probably safely push the engine to 8750, maybe 9k. Raising the redline was not what I was refering to but having a custom mix and match ECU software in a M-DCT with parts from a MT car.

I agree, why in the world would anyone use MT software on a car as sensitive to software as the DCT? It just does not make sense.
