I have a schematic for the ebcm system on my truck, I have verified that it is getting correct signal from the button to the ebcm, which it is. It just has some kind of software that overrides the switch once the wheel speed and yaw get out of line, even if its disabled. I guess I'll just do like the others and intercept the power wire from the fuse box to the ebcm and install a switch.

 

That is what I am thinking about doing, I wonder if you could just use two jumpers and an inline fuse and use a switch to interrupt the circuit?

 

On mine i notice as long as i go wot and stay there it will do what i want, its when im part throttle or in and out that it will kill power. Like if i turn the tcs off when its dry i can power break it and go white line to white line as long as im wot constantly. But i notice in the wet or snow when im in and out of it or at half throttle in snow is when it will activate. Why is it like that?

 

i dont have this problem at all....

my truck, in 2wd or 4wd, will do donuts all day (well, "cyclones" in 4wd). this is of course after i hold the traction button for 5 seconds, and it says "Trac OFF", then "Stabilitrac OFF".

my truck is running a stock tune right now.

2010 4.8l 4wd, like it says in the sig.

 

Tested it out today a good but and the only way I can truly get it to turn off is by pulling the # 9 fuse as Area47 explained so I will be building a circuit this week that will interrupt the circuit controllable with a toggle switch.

 

I confirmed the same thing. I will say this though, with the converter in now, Stabilitrak is not limiting me now?? I disabled a bunch of the transmission fault enablers because of the converter and I can roast both all the way through first and into second with a 4.8 w 3.23's

 

I wired the fuse power through the normally closed contacts on a relay and then use a SPST toggle switch to activate the relay when it is time to set the 6.2 to KILL MODE.

 

can someone post a wiring diagram of how they did their switch, and or relay? im getting mine tuned this weekend, and i would like to wire this up at the same time.

 

Cut power wire from fuse box to ABS module CONNECT: terminal 87A to one end Terminal 30 to other half of wire. This is the closed contacts of the relay.

Ground terminal 85 of relay
power from toggle goes to 86 of relay.

Terminals 85 and 86 are the relay coil terminals you can switch power or ground between terminals and the relay works the same.

When you activate the switch it energizes the relay breaking the relay contacts and de-activates the ABS to put truck into tire fry mode.

I just spliced the switch power into the same wire that powers the abs module so I did not have to hit any external 12v sources in the truck

 

so doing it like this, you are running an external toggle switch, or are you using the factory TC button as your switch?
