This is so off topic, but in the future if you get the DCT TCU cracked, could you get the M3 launch point hardware to work on the 335? That would be a neat modification I think.

Did a new video for the ones that like to drift with their 6-AT! ;-)

So the format for this will be similar to MHD in the sense that you plug it into obd and pick an ots map? Also I thought they didn't have the e9x series cracked yet, but I guess proof is in the video.

This is the 335d? And the tcu is the same to crack since they are both second gen 6HP

Also the video caption explains that this is a new feature. Being able to hold it in gear in manual mode without auto shifting. several people wanted this. Here it is.

Did you shift into 3rd gear? It seems to stay longer in the selected gear but couldn't hear you shifting that's why I ask

Yeah, I recognized later, that the "click" of the paddle is not really hearable in the video. But, yes...i shifted. In stock it shifts at 4800 rpm and now it will drive forever at 5200 rpm....that's where the ECU blends out fuel. Hitting limiter isn't that spectacular in diesels. ;-(

So, As far as the RPM band.. Have you heard of testing with the n54 in high RPM?

There's no reason, why things should be different with any other engine in front of the 6AT. The TCU program is the same, the limiter positions in the calibration file are the same. Beta phase will confirm, but you can take that for granted.

No, I mean... Has there been any testing that you have any information or feedback of. Like do we know how the n54 acts after 7200rpm?

Meh I don't even care about higher rpms. I'm more interested in the performance drivability and reliability this will give

They have not started testing the 6hp21 yet, so they personally, don't have any information on the matter. Unless its been kept secret. I think they are just focusing on the 6hp28 for now. But there are a few 6at's that have gone up to 7500 or so in first gear.

Hmm, think I don't get ya? On a manual car, the ECU limits RPM by cutting fuel at a certain point. On an Auto Car the transmission usually limits slightly before the RPM limiter from the ECU would kick in. From an average consumer point of view, it's more desirable to be shifted to next gear, rather then hanging in the limiter.

So, when removing the limiter from the TCU, you will experience the normal rev-limiter from the ECU, in the same way you would on a manual car.

What I was asking was, if you had heard or seen anything for the N54 w\ 6hp28 revving high? It was just a general question not a "Have you though about this" type deal. I am looking forward to seeing what this brings to the table :)
