yes..........if the tcs is turned off in the tune, the button is always lit, you get a message in the mess center that you can clear with the reset button, and you can't turn the tc back on with the button....
Yup. I personally don't ask for it to be disabled. I like to ability to use it if I want. If I'm going to have to hit a button anyway, I'll hit the one to disable it.
My BamaChips race tune does not turn off the TCS. I specifically asked Doug about before I ordered, because I didn't want it turned off. He told me that he doesn't turn it off unless someone requests it.
