I notice no difference when using it on a highway pull, only in corners and launches. Why do people use comp mode in highway pulls? It kicks off TCC that's all I can think of, no HP or boost change if un-tuned. Can someone explain this please...

 

You're correct.

Competitive mode:
1) Turns off traction control
2) Enables launch control
3) Waters down electronic stability control a bit to give people more flexibilty on a course

As far as highway pulls, there's no difference from the traction off option. There are no programming changes made between tuned and not tuned, except for some people changing the neutral gear RPM limit to artificially change the launch control RPM.

 

If the wheels spin the car cuts power. So having Traction Control of is big time.

 

Exactly.

 

Ok. My buddy and I argued if it changes anything HP related, I'm stock so I don't really have to worry about wheel spin on a highway pull...

 

Some people who are tuned tie their high-boost programming to competition mode.

 

yeah no big difference
i could tell a slight difference around corners though

 

Yes, that is true with the Trifecta setups, and I forgot about that facet. That's not something the car would normally do on its own though.

 

Is NLS not tied to competitive mode?

 

No it isn't. You can NLS in any mode.

Many people do put it in traction off/competitive/ECS off modes though, so there isn't a chance of the ECU letting off to let the car catch its footing due to wheel spin after an NLS.

 

Competition mode does not disable traction control. The very fact that it enables launch control should tell you that traction control is on, but toned down. Launch control is based off traction control. It allows up to 30% slip before cutting back on power.

Also, a GM engineer (GettingAUserNameSucks (sp?)) on this board stated that NLS only engages in competition mode. I presume it also works with full traction control off mode. Otherwise, it's probably just like NLS in any other manual car.

 

No sir.


Traction control is off.





...and NLS works in any traction mode.

 

Meh, ok, I concede that ESC is still on, but it's a form of traction control, which is what I originally said. I didn't use the acronyms TSC or ESC in my previous post. Launch control works by nannying the amount of slip on launch.

Regarding NLS. That's info from a GM engineer. He also specifically put "It's my job to know" in that same post. You can judge for yourself.

Cool ok.

I couldn't care less who's right. I just want to make sure that we've got the correct answer.

Good info btw.. I had never seen that.

 

Well i have used NLS in all modes and I know this because boost has not dropped. Plus the manual states it works in in all modes so that "GM engineer" needs to provide some written data to the fact that is more credible than the instruction manual.
