To kill the traction control you have to open up your mid-console and rip out a Bosch modulator. That's not in the FM...

Bosch modulator? Is that the thing the Mars Martian needs to blow up the earth in those bugs bunny cartoons?

That's interesting. When I turn VDC off, I sure don't have any traction control. Just ask the last pair of rear wheels that came off my car! ;-)

So off is all off ?

Not this 50-50 stuff?

That's the Q38 explosive space modulator.

This is correct. Traction control is still on even with VDC off.

However with street tires and LSD it doesn't really seem to be an issue at the auto-x. There typically isn't enough traction to lift the inside wheel to the point that it will spin freely so instead both wheels spin when you juice it in a corner. With sticky race tires it is a different story, and I've had the traction control intervene when trying to accelerate out of a corner. It's a little annoying but the intervention isn't that painful.

So yes, traction control is still on partially, but it only intervenes if there is a large differential in speed between the 2 rear wheels. You can still do burnouts and donuts to your hearts content if that is your thing.

Yes, go back to your cartoons and leave the cars to the real men.

Ignore the morons, it's a lost cause.

Okay... If you leave Traction Control button ON. Which is default when you turn on your car. Your back tires will automatically brake, preventing you from spinning your car if one tire spins faster than the other.

If you turn it OFF. You will get less of this auto braking.

If you perform a Launch on your car, drop the clutch pedal. with the traction control button ON, your back tires will begin braking and your purpose of your launch is messed up. lol

If you take short fast corners with this botton ON, your back tires automatically brake.

So in other words!!

TURN OFF if you want to drive aggressively.

Leave ON if you choose to drive like a normal driver.

END.

The traction control is never completely off.

True. I always drive with my VDC turned off. I honestly dont remember the last time I forgot to turn it off. It is habitual now. I also dont know how many times with it off it still will kick on, not bad, but enough to notice, then I look down and it is blinking.
