The only way to get it to turn off completely is if you had a new ECU and Transmission control module. The cars ECU has the Traction Control relay wrapped in with the Electronic Hydraulic system. If you turned it off completely, your car wouldn't be able to shift properly. It would potentially get stuck in shift lock. Your traction control system is one of the key players in regulating the pressure solenoids. If you don't know what I'm talking about. What it does is regulate the amounts of pressure applied based on the Voltage levels running through it. Here is an example of how it works. Say the that you driving and your running temp is 221 degrees(F), the voltage running through there is 1.83 Volts w/ a resistance of 1695.0. Now if you car was running at lets say 293(F) the voltage increases to 2.11 volts w/ a resistance of 2148.0. So you see when the voltage increases, so does the pressure, and the traction control helps to regulate, as well as make sure that its getting done as well.
I guess the only way you can trick the car is, if you some how fooled the speed sensors around on all four tires, as well as your Horizontal Accelerator sensor. If you can get them to all read at the optimal levels at all times, then you would be able to burn out and have the traction control system thinking that your fine. It wouldn't be easy to do, but I'm sure someone could do it. I hope this helped you a little bit. Oh ya and by the way welcome, were all a bunch of performance freaks, looking for the stuff to make our cars look cooler, or go faster.
