As I understand it even with the Stabilitrack disabled it will still still engage in some way if it senses excessive spin... right? Correct me if I'm wrong.

So my real question is can this be bypassed with a tune or is the traction control/stabilitrac stuff not controlled by the PCM? Are these things that could be tweaked with HPT?

I'm new to this whole thing b/c with my Silverado SS there wasn't traction control to worry about.

 

im not sure... but i can do a stand still with just traction control off isnt that excessive wheel spin

 

I can too, but I thought I had read somewhere that you couldn't COMPLETELY turn the traction control or stabilitrack off... but again, I could be wrong.

 

but it does stabiltrac off...y not go ask on trailvoy.com

 

Pressing the button once turns the traction control off, holding the button in for a few seconds turns the stabilitrac off.

 

what is stabilitrac and how does it work?

 

I understand that, but I've been getting mixed responses on whether it turns it COMPLETELY off.

 

In low-traction conditions like ice, snow, gravel, wet pavement, and uneven road surfaces, electronic stability control systems like StabiliTrak, are proven to help reduce single-vehicle crashes.

Using sensors, StabiliTrak:

1) Detects the difference between the steering wheel angle and the direction you're actually turning
2) Applies quick, precise force to the appropriate brakes to help the driver control the vehicle’s direction to help keep it on course

StabiliTrak is available today on many GM SUVs, vans, cars and trucks.

 

There are also tables like launch conrol which pull timing similarly to torque management. A full PCM tune can remedy this, I think HPTners also has it covered.

Stabilitrak is a bitch... We've done several dyno runs with our's and I just know when it kicks on at about 30mph, its robbin about 25-35 hp or more..
Basically how it works is cuts power to the engine to let the wheels slow down, but not stop. Traction Control is the one that I think applies the brakes
