Nothing the TC only engages based off front tire spin vs rear tire spin. It has nothing to do with any left or right movement. Its just launch control for dummies so you dont roast tires from a stop. Causes the rear brakes to clamp down. You can leave it on it wont hurt anything. The TC will still function like normal on. I just always had mine off, unless it was raining or snowing. It can be helpful then.
