Can you pull the fuse for TC? I know the TrailBlazer SS has this issue on the dyno and lots of guys pull the fuse and dont worry about the rear brakes applying while they are dynoing.

Hmm, then Im out of ideas.

Just wanted to make sure you werent on the dyno and have the StabiliTrak kick in and give you some red rear brakes!

Hi Ross
You can maybe set the available torque for traction control to zero and reduce all the timing subtractors. But im not sure that will work.
I havent had trouble with Crewmans laying rubber :) but i guess you need it for the dyno.

Is it a 4wd hub dyno ? , the system needs to be setup so all 4 wheels are going same speed or you will have issues , dynapackl should have software to suit

pretty sure the traction control is linked to the ABS on these things and can't be disabled.
I have played with one, zerrowed out all torque management, TC, etc and it still would not do doughnuts on a sandy beach :bash: ABS just applied brakes :nixweiss:

What if you temporarily disconnect the ABS wheel speed sensors? For offroad testing only of course.

For the dyno to operate correctly all 4 wheels need to be going at the same speed or it will activate the brakes to the faster wheel to get them all back into synch.

This vehicle has a open centre in the transfer case so they cannot be run safely in 2wd more or on a dyno that doesnt have a speed matching program on the front to rear retarders.
