so do you guys leave your balt ss/tc in comp mode 24/7?

what is the difference between hitting button once which turns traction off and hitting it twice? same settings? is the traction turned back on once your in comp mode?

also, does turning traction off and/or using comp mode sharpen up throttle response and/or acceleration?

if traction is truly turned off , is that related to our optional LSD? (which helps with traction??)

oh, btw, i'm bringin her in to get checked out on saturday. i think the steering wheel is misaligned with tires, basically when you set the steering wheel dead straight as your cruising down a crownless highway, the car slowly starts to go to the right. turning wheel slightly to left keeps it straight and that darn sqeaking clutch pedal, hope they oblige and make the fixes under warranty!!!

 

As for the specific of what traction control system are affected, I will leave that to more informed members...

But I can tell you that the Comp mode button does nothing for throttle response or acceleration (other then what the traction changes might give you)

My BMW M3 has the "Sport" button which has a HUGE impact on throttle response (far too much in my opinion) but our cars don't change that throttle response change.

If you want to turn everything off, hold down the button for 5 or so seconds and it will notify you that all system are offline.

I dont usually turn on comp mode....and don't notice a difference during highway acceleration.

 

ur wheels are out of alignment, mine does it to a little, dang gm seems to do that with alot of cars.

 

Turning off Traction Control lets your tires spin all they want. Traction Control cuts power to the engine if they start spinning, so it just doesn't cut power.

Comp Mode turns on Launch Control and No Lift Shifting. It also ups the parameters for activating the Stability Control so you can take corners faster.

 

i turn on comp mode everytime i get in the car. i got in the habit of doing it everytime now. i like it better. i like being able to have the tires spin and not have the engine cut power plus i just like knowing that the nls is there if i want it.

 

The braking system intervenes as well when your traction control is activated...much better than the old systems that just cut power.

 

you dont have to be in comp mode to have NLS

 

That's what I thought as well. It's been discussed multiple times. I hardly ever put mine into comp mode because it's not very often I need it. Sometimes I'll turn the traction control off completely if I want to spin my tires a bit. I imagine I'll use the comp mode when I go to the track this summer though. I'll have to try comp mode and compare it to no traction control and see what they feel like on the track.

btw if you have your car in comp mode or tc off once you turn off your car and turn it back on it resets to full tc.

 

as for no lift shifting your wrong on that one. you can no lift shift without comp mode. try and see for yourself if you dont believe me.

 

Unless our cars have different traction control than most, Im pretty certain that Traction control works by applying the brakes to a wheel the computer determines is spinning. It does this via the ABS wheel speed sensors....if the computer sees that a sensor is registering a speed much higher than the car is actually moving it intermittently applies the brakes to that wheel, sort of pumping them, the reverse of ABS(which pumps the brakes when the wheel speed sensor detects the wheel is moving to slow for the actual speed and other sensors, or is locked up all together, the ABS then releases/applies/releases/applies etc. or "pumps" the brakes to allow for a controlled stop).

 

read your owners manual
chapter4-pages 7to 10 it should clear all this up

 

my front end was out of align as well(as well as had a bad wheel bearing)... they fixed it and replaced all 4 tires... really only one tire was worn, but I didn't complain with 4 new ones, took about 2 weeks for the tires to come in though....

 

Thank you, no one seems to take the time and read the owners manual anymore.

 

should I post a picture of it to lesson the number of new threads as to which book is the owners manual and the warranty manual?

 

This is correct, except many cars will limit the power applied to the wheels as well as braking. TC and VSC is also different than ABS in that it uses the pumps to build pressure to the wheels, where ABS uses the pump to evacuate the accumulated fluid that is dumped off from the wheel that has too much pressure applied.

 

My manual doesn't say anything about competition mode or NLS. Does yours?

 

Really? comp. mode 4-9



no lift 2-30 part of the manual transmission operation section.

 

Thank you! The manual for my 08 doesn't have either of those sections...

 

Your welcome, seems weird gm must have updated the manual for the 09's

 

Weird indeed. Maybe the people responsible for keeping the manual up to date were laid off... or maybe they're just incompetent.

 

That info came along side the original manual, it was just a sheet of paper until now.

Not sure if this was mentioned above or not, but IN ORDER SHUT ESC OFF THE BUTTON NEEDS TO BE DEPRESSED FOR 7 SECONDS, You will see ESC OFF appear.

 

mine isnt in the manual, but it was on a paper in the bag the owners manual came in. i have an 08 also.

 

does this affect the ECM/ECU when it's tuned or flashed??

 

Tuning is all about changing the ecm, tunes however have no effect on the traction control/esc or the competivie mode parameters. Vince will however suggest that you do not use the no lift shift after tuning.

 

Mine defintely didn't come with that paper.
