How to Dyno 2011 DCT

TMR · 12-03-2011, 01:14 AM

I tried searching and couldn't find a procedure on how to dyno a 2011.5 DCT car. I can get 2 clean runs then the car drops the rev limiter.

Anyone?

I dont think it's only DCT that drops the revs like that on the Dyno. It's the ABS signal being sent to the ECU calculating each individual wheel speed and seeing that the rear wheels are in motion while the fronts are not so it puts the at in a safe mode But, have you tried to shut off the DSC on the Dyno before doing a pull ?
Also, you can always restart your car and it will be clear to do more runs.

I turned off my DSC and was able to do 3 pulls on the dyno without any problems

DSC off, 4th gear. Should have no problems.

if you cant get dsc off go to into m mode and turn it off there and your set to go in 4th.

I've had issues as well. Couldn't get past 2,000 rpms in 3rd gear without a rev limiter dropping around 5,000 rpms. Ended up pulling the large 40 or 50 amp fuse for the dsc and getting the car to do one pull. Then had to reinstall the fuse to get one more pull, followed by a third pull with the fuse out again. Mixed in there were some ignition on/off cycling and dme fault clearing. Very strange... Would like to find a better way to get this done. I'm somehow shocked not to see one of the tuners respond here?

When they are unable to resolve an issue they all become quiet
