Flipping the switch shuts it all off. However, I have learned something. It seems that if I flip the switch after starting, it shuts off that WSS, that'* why only the right tire spun and the left still had TC. If I shut it off and then start the engine, both are shut off.

2000'* may have a problem trying to do this mod.

Do you hear the braking system kicking in? I have only one disabled and have no issues with any TC. Dan, please check the FSM (at work here) I'm pretty sure when I checked it, it says that if one faults, then entire system faults because if the system worked only one side that could pose a safety issue. If that proves out then the below should apply.

When I did this, I already had the LSD. Being that you have an open diff, one side can and will spin more than the other if the wheel is turned, traction is slightly different etc etc.

I did not hear the brake kicking in. But looking at the tire mark on the driveway I can see the pulse, it gets dark then lightens up and does this over and over. The other side was solid and dark. Starting the car with the switch off I got two even marks.

now children stop tweaking the cars to do better burnouts, you dont want to spin the tires, you want to launch out of the hole! hehe the 1/4 mile drag isnt a burnout contest for a 1/4 mile lol
j/k
the GTP burns both solid with the TCS off, and pulses both with it on but will boil them no prob either way.... sadly ive been having to baby her cuz its rained for the past 2 weeks... wet roads, lots of torque, not good for tires lol

So does the GXP TL. Wren use to say you had to pull the WSS as well, (to defeat other programed limits) ???? I dont know if it was his typical "I know more than You" runaround, or if it'* a year/model thing, or ??? Doesnt seem pulling one WSS does any more for me than just turning of the T/C.

And oddly enough I have different experiences with 97 than Dan. Dan, I'd like to see you test it the other way. Unhook your driver side and leave the passenger hooked up. See if you get a weak right wheel burn.

I pulled the drivers side and got even burn outs. However I pulled it and then started the car. When I shut down the left side it was with the engine running. I'll try to get some pictures and a few more tests.

OK bill, this is what I got. I'm no expert on reading schematics. But, it sure looks like the LH WSS is different from the rest.
