This is the first dct car I’ve ever owned or even driven. Is it normal to have to give it more gas to take off vs a normal automatic transmission? For instance pulling up my driveway into the garage it seems to hook and unhook or very slow maneuvers in a parking lot. Seems fine once you give it a little gas.

 

Yes, DCTs mechanically are similar to manuals. If you've ever driven a manual you know what is required to finesse the clutch to get a smooth take off. The DCT is doing the same thing just without you doing it but you still feel it.

Throttle input will dictate how it grabs the gear when you get going.

 

This is my 5th car with a DCT and I don't think the issue has anything to do with the trans. I had the same exact issue with my car and reading here I was pretty sure it was the throttle maps issue. There are multiple threads. I bought a $208 Soler throttle controller and put it in before I took her out of winter hibernation. It is the best short money you can spend on our cars. It is loaded with a bunch of throttle maps with several setting that be adjusted on your phone and it absolutely transforms the car.

 

Yes, this is normal. When you come to a stop you can feel the clutch disengage, and when you start going again, the clutch has to re-engage. The speed with which it re-engages is proportional to how aggressive you are with the gas pedal. Plus, I believe it has hill assist, which holds it at a stop on a hill for several seconds after you release the brake to allow you to get your foot over to the gas without it rolling downhill on you. I find that to be an additional element to be aware of, so you don’t overreact on a hill when taking off. Each different DCT has a particular character to it, and the one in the C8 is actually pretty good based on my experience. The base C8 is a little smoother but the extra clutch plate in the C8 Z06 allows for some extra crispy shifts. Porsche’s PDK is the best I’ve tried, and it even mimics the forward creeping motion of a torque converter automatic, where it rolls slowly forward when you release the brake, without touching the gas, which most DCTs that I’ve driven do not. Clutch engagement on the F10 M5 left a lot to be desired. It had a difficult time doing a moderately fast takeoff smoothly. They seemed to improve on it in the later F82 M4, which was notably smoother, albeit while dealing with over 100 less hp.

 

my z06 does the creeping motion when I let off the brake maybe your right about them having there own characters lol

 

the rpm’s need to be higher to respond the way you want it to that’s the difference from a flat plane crank the base c8 wouldn’t do that with the 6.2

 

Has nothing to do with plane of the crankshaft. It is not an automatic and does not have a torque converter.

 

An automatic transmission is not defined by if it has a torque converter. If there is no 3rd pedal it is an automatic. A CVT, a DCT or a torque converter are all automatics. You are not doing the shifting the computer is.
