Traction control question in regards to drag racing.

Mysilverz

So I was drag racing with a friend at a local track and my traction control light would flash on launch even though I had the traction control off. I thought nothing of it at first until he told me it sounded like it kicked in for a moment on launch. So my question is what is happening and why? I'm not new to drag racing and I certainly don't want any electronic tweaking while I'm on the track. Also is there a way to turn this off? Could the ecu be Miss interpreting something? Maybe theinking I'm losing control in a turn? Would a switch on the yaw sensor solve this problem? Oh and the car is a 2013 370z base sport with 14,000 miles. Everything is stock except a stillen gen 3 intake.
