Engine drag message
I got a DIC message for a fleeting moment reading "engine drag". It didn't create a warning tone. If I hadn't just been looking down at the time I would have missed it. Anyone ever seen this before? Clues?

Engine Drag control
"When the driver releases the throttle and the drag from the engine overcomes the frictional force between the tire and the road EDC becomes active."
EDC will increase the torque at the wheels to reduce the slip...
Sounds like you were slowing down using the engine and the rear wheels were starting to slip. The active handling was kicking in to stop the slip.

This issue has only happened once in 1 1/2 years and 28,000 miles that I know of. I would have missed it if I hadn't just been looking down at the time as there was no "bong" warning from the DIC. The car is an automatic although I have used the paddle shift option on occasion. I was just wondering if I had an engine problem lurking. Best I can tell from the responses is I don't. Thanks.

I had the same problem right after I got my car tuned. My car would also jerk like you slammed on the brakes. I think it had some thing to do with screwing around with the shift points, but I really don't know and my tuner doesn't know either. I had to take it to the dealer and they set everthing back to stock
I tuned it again with a predator(which isn't as good) and know more problems.

To CK 6, were you downshifting the paddles when you got the message ? Pretty nice feature to keep you out of trouble on a slippery surface. A6 here for a year, have paddled some, have'nt seen the message.

No, actually just normal driving. BTW, it has happened again since I first posted this. Goes to the shop today.

Follow up. From the Service Manual:
"Engine drag control active: This message displays when the engine drag control is active. When driving in a lower gear in rainy, snowy or icy conditions, and then letting up on the accelerator or downshifting, the rear wheels may begin to slip and this message appears. This message will stay on for a few seconds following the engine drag event."
FYI, mine came on in complety dry road conditions, but I did let up on the accelerator at the time. My technician has not encountered this situation before and he is an experience Corvette mechanic. His thought was I might have gone over a newly painted strip causing the rear wheels to slip thus triggering the message. Beats me.

the C6 is a smart car.The automatic transmission notwithstanding....I find doing a tradition 'heel/toe' is virtually impossible on the C6 due to pedal placement. I 'roll' my right foot from the brake pedal to the gas pedal but under heavy (track) braking I don't feel as secure on the brake pedal.
I remember reading about pedal modifications to help cure this or I might eventually try the Elite Engineering pedals.
