This topic probably has been hammered out before but since I have now tracked my car for 2 seasons I have questions. 2016 Z06.
I run in Track mode, Sport 1. When I'm driving on the track at an easy pace the traction control light does not come on, but now that I'm driving more aggressively, it clicks on a lot.
It seems to click on more often than ever before, even when I don't think it should. In other words, when I'm not driving that aggressive. My buddy who is very experienced and an instructor, feels the same way when he drives it now, whereas it didn't seem to before.
Could the system "remember" or take a more conservative set?
I'm hesitate to go into Race mode or even Sport 2.
Any recommendations?

 

Did you turn off the Traction Control & Stability Control while in Track1? When I was at Spring Mtn we used Track1 with TC & SC turned OFF. The TC & SC settings revert back to ON when the engine is turned off and will need to be reset for track use.
Oh, by the way, I was in a Grand Sport, pretty sure it would be the same with a Z06.

 

Based on the way I read the manual it seems once your in PTM the TC is off, but SC is still on best way to confirm would be the lights on the dash.

How worn are the tires? Fronts good, but rears gone? Maybe they have plenty of thread but have been heat cycled too many times. What about tire pressure? Track temperature differences? Sorry just throwing darts here. Could be your confidence is just higher now and thus you are pushing harder even if it does feel that way.

 

Tires are losing grip as they age and wear.

 

Traction control isn't on when you are in Sport 1. However, PTM and Stability Control (Active Handling) is on. The light with the squiggly tire marks will flicker when stability control or traction control have been activated. Since you are in Sport 1 you are more than likely seeing some Stability Control action. This could be caused by several things; First, your tires are losing grip and the system is reacting to correct the yaw response (understeer/oversteer) of the car; Second, you are gaining confidence and driving faster thus bringing you closer to the edge of grip and the system is reacting to slight errors you are making while driving. This could be caused by too early turn in, too early throttle tip in, slow unwinding of steering wheel coming off a corner, etc. Stability control reacts to where you have the steering wheel pointed and how fast or slow the car is responding to your steering input. A slow response is usually understeer and too fast of a response is usually oversteer. You can get oversteer in a corner by slight lifts off the throttle that you or your instructor might not notice but the system notices and corrects the oversteer through brake application before you notice it. You can also get power on oversteer where the system will more noticeably correct a situation by cutting power; Third, it could be a combination of wear and improved skills. One of the things about improved skills is you need to improve to the point that you recognize changes and adapt your driving style and line to accommodate to those changes. That skill usually comes later rather than sooner.

I don't pay a lot of attention to the IP when I am running hard as I usually focus on the HUD and what is far in front of me with only occasional glances at the instruments when I come off a corner with lots of straight ahead of me. Thus, I don't really know if the light will flicker when PTM is active. If you have improved to the point that you hear PTM modulating the power delivery (sounds like a truck using a diesel jake brake to slow down) to the rear wheels as you drive off the apex of a corner and notice the light flickering at the same time then it does light with PTM activation.

That is what I thought. Track Mode #4 and #5 (Race) shuts the SC off per the manual, so stay away from those unless your really experienced.

I almost wish the TC / SC lights blinked in the HUD, as that would help with the learning curve and understanding what the car is doing.

 

Just go to sport 2 and have at it. I find the system way too invasive at anything less

 

From what I've seen, when active handling (a form of stability control) kicks in the light flickers. When PTM kicks in, the sound changes (like Bill mentioned) - I haven't seen the light flicker. I run in PTM Sport 1 as well and I've seen it interfere only towards the end of life of the tires (like 6th or 7th track day on a set of NT01s ). I think you should be able to see this data from PDR as well - I remember seeing channels for ABS and Stability control. I'm guessing there is one from PTM/TC as well.

 

Sport 2 still interferes if it sees slip. Race still does also. Manual can say whatever it wants but it's not true.

It really only interferes on throttle application at corner exit. The throttle cut sound is REALLY obvious. Maybe you can hear on one of my videos. Check around 3:55. This is sport 2. I'm overdriving and it allows quite a bit of play but sometimes it triggers when I really could just power through and lose less time.
