Maybe. I need to do some data logs of "vehicle speed" which supposedly averages the four wheel speed sensors and "driven wheel speed" and "percent slip" all of which are parameters the ECU uses to gauge whether it needs to activate traction control.

It's kind of hard to get data on this stuff, the way I've been doing it has been by doing pulls up my driveway, which is pretty long but still not ideal.
