Hello Everybody,

I just purchased a 2006 standard, with auto and wide body conversion last week. I've driven it only a handful of times, but each time it seems like the rear tires break loose far too easy. I'm not sure if what I'm experiencing is normal, perhaps it is. The car is mostly stock, other than a CAI and a tune. I live in SoCal, but it's been pretty cold, so perhaps that's part of it, along with the 325's in the back. I do have a manual C5 and it take much more effort to break the tires loose, so I'm just wondering if there's something going on, or am I just not used to this car. BTW, the traction control is enabled at all time right now.

Is there a do it yourself way to test the traction control system to insure it's functioning properly?

Thanks

easy way to test is to just try it both ways with traction control turned in the on or off position.you will then easily see the difference

My guess is cold tires. Summer performance tires are crap below about 40 degrees.

Thanks for the replies. I can't believe I didn't think to try the traction on/traction off test. I not too worried because I thought the car would hook up fine on a nice warm road, but right now the car is a little scary to drive. I'm fairly new to owning a corvette so wasn't sure if there's a common problem with the traction control.

How old are the tires? What's that date code on the tire?

Also depends on age of tires, tread wear, and brand of tires. My 10yr old tires (soon to be replaced) have plenty of tread left, but spin for days bc they're old.

You guys may be on to something, treadwise the tires are fine, but I'll definitely check the date this evening.

Tires show 4411, so that we're talking about seven year old tires!! So does this mean I get to do all the burnouts I want this spring before replacing them for the summer ......or do I need to get these off ASAP?

You'll probably be fine if you don't have weather cracking, but best to move on. Make a smokeshow and then replace 'em. That's what I'm about to do.

I've wondered about the TC on the C6 myself. My car has the original tires on, it's a 13. You can pretty much ignite them at will and I have never seen the car react to Tire spin. No I haven't tried to smoke the tires but they surely break loose enough that my C5 would have cut the ignition and the engine would fall flat. I don't know what percentage of slip it takes to engage the TC but it's definitely set higher or differently than the C5.

Read your manual 4-6.

In a straight line I can light them off and both spin, no throttle cut, etc. Very different than the active handling engaging. That chops the throttle.

What do you know about the "tune"? A tuner can disable TC in "torque Management" in the tune. I know BC I've done it.

That said, there is always a slight break away before TC kicks in, but a lot of new drivers are taken off guard and quit before that happens. Do the test suggested above and if there is no difference with TC on or off, then suspect the tune next.

This is not the same ECM as yours, but a part picture of what's available to the tuner. These are the factory settings, but I can disable a couple of these fields and there will be no TC, no lights, no nothing.

I know mine hasn't been re-tuned. And every C6 I've driven or ridden in acts the same. I've never put my car in a slide to test the attitude sensors and mine does have active handling. I'm not sure if all C6s have that or not. If it's controlled by sensing when the wheel slip exceeds a certain percentage (which is how I suspect it works), then I'm surprised mine hasn't engaged yet. But if that % needs to be high unless the car attitude is headed sideways, then that would explain it for me anyway because I've never come near 'losing it'.

Once again thanks for all the responses, I will certainly reach out to the tuner along with some testing once we warm up.
