View Full Version : How does torque limiting work?

Next year I told my daughter she can race my firebird and right now It will be faster then I would like her to be so I was going to do a few things to slow it down.

I'm also worried about traction and she does not have the experience to feather the throttle on the launch and therefore would be inconsistent and would hurt her chances of winning.

So I was looking through the tun file and I see the torque limiting section and I was wondering how that works and if I could use it somehow to slow the car down and or reduce the launch torque to keep the spinning to a minimum. How does it activate and what sensors are involved?

Hi Dragster:

Not exactly sure how to remedy your situation, but you could always lower the rev and speed limiter.

Local friend with a licensed teenager locked in his max speed to 100 mph. The car has over 500RWHP, so that was how he did it.

If you have traction control, you could tune that to suit.

The torque reduction is more there to save the trans i think.

you could just detune, pull timing, add fuel.

or maybe lower shift rpm on 1-2 shift and increase torque reduction on shift to reduce wheelspin.
