N55 7 speed DCT DYNO

I'm putting the car on the rollers finally tomorrow!

First off, anyone dyno a DCT car? What gear should it be in? Sport mode? Dct on or off?
Power Mods are...
-BMW performance tune
-AFE intake
-ECS charge pipe
-Active Autowerke axle back

I have no clue what to expect, but will post dyno charts tomorrow...

DYNO sheet.....of course my scanner decides to not work anymore so I took a couple pictures of it.
It was done on a Dyno-jet







If its too blurry....
1st run 288.45 whp 306.57 wtq
2nd run 293.29/299.77
3rd run 292.49/302.31

Pretty happy overall. Next on the list will be Active Autowerkes FMIC.

This is good news! So what gear did they use? Sport mode?

No idea sir. It's up to the tuner. I don't think sport mode does anything to the power. Sport mode just makes the throttle more responsive and the gear changes more aggressive.

Those are great results from stock + exhaust! On a dynojet I was at 257/268 with SAE correction factor with the same thing! Talk about a huge difference.

I think with the DCT it should be same as a 6mt. Generally they will put it in manual mode in 4th gear to do the roll with DSC off.

285 should be doable on dyno jet.
Manual mode, sport mode, dsc off, 3rd gear that's what i did on mine and put down 299 on super flow dyno.

I did mine on a Dynojet. HP=284.82 Torq=291.69. My 2011 w/ dct, PPK1,and Mad dad whisper cat back. I was hoping to be at 300 hp, so I was a little dissapointed. The issue was the dct., it just kept up shifting. I was in sport mode with dct off. The guy running the dyno didnt really know how to work with a dct trans, so I will be interested to see how you do.

I am guessing you have to be in manual mode, and the guy running the dyno cannot go past the kickdown.

3rd gear? I thought you are supposed to dyno in the gear that is closest to 1:1.

Yes, on old tech RR's that would be preferable, but 1:1 in a DCT car is 7th gear as 7th is direct with a 2.56:1 rear end ratio.

My stock 135i with DCT was dyno'd on a Dyno Dynamics in 3rd in manual mode with DSC off, avoiding the kickdown, and ran 256rwhp.

I think they ran my car in 4th gear.....I could be wrong. Either way, the power makes sense given your stock numbers plus my mods I have.
