Traction control, wheel speed sensors... who wants 'em?

Nope, you're Rtek wouldn't be able to use these. You would need the Race Logic box to take advantage of these.

The RL box doesn't adjust the boost, nor does my ECU. I've got my boost control as boost vs gear and boost vs tps and boost vs trim switch and boost vs how aroused I am so adding the TC is really like adding a back-up. I can run a more aggressive boost curve and let the TC do it's thing when the ass step's out in the higher RPM's.

You're right though, the basic idea is to sense the difference in speed between the rolling wheels and the driven wheels, taking into account a difference in wheel speed in the rear when turning, and soft cutting the ignition. Brian is excited to see these things work
