A DPDT switch (AKA reverse polarity switch) will work just fine but you'll only use one pole of the switch. A SPST switch will also do the job and should be cheaper.

Thanks for the reply I'm going to check for the cheaper regular two pole. But all they seem to show online is the reverse polarity. I would assume they would have both but figured I would check just incase

Can anyone tell me if this will let me stand on the brake and do a standing burnout for the drag strip, there are so many posts of people that do this mod and they say they don't know , not sure, haven't tried it blahh blahh , so who can say for sure yes or no that I can do a standing burnout with the brakes?

Unsure; as I added line-loc to mine also...didn’t want to fry the rear brakes.

A yaw switch will not allow standing burnouts; you need to pull the stop light fuse. There is also at least one DIY on how to install a switch to accomplish the same thing (breaks the brake-lights-are-on signal to ECM).

The other option is the throttle hijack feature from Ecutek.

I just got mine working, and the software changes to the ECU will now allow me to burn rubber with the brake on as far and as long as I want.

My yaw sensor has been disabled for years. That had zero impact on burnout capability.

What actually happens in your case, is that the throttles will be closed, if the ECU sees the brake switch on and the gas pedal voltage high. This effectively prevents the driver from pressing the brake and gas pedal at the same time. The yaw sensor is not an input in this case.

interesting...did yuou have to splice any ecu wires or is it straight to ecuteck via exisiting? im about about to finish off my flex tuning in the spring and might ask to have this dropped in on my phone app (bluetooth dongle).. do you know if that kills ice mode as well, or is that an abs hard disable?

BTW..

as of time of this post, i found the switches on amazon... they cost me a buck & change each and fit perfectly.

i already hooked up my pump speed controller override, the vdc bosch box is next and have duct fan control on #3 in the works.

only thing of concern.. watch your wiring, your e brake can bump and possibly snag the wires, so keep that in mind...

and for petes sake, use spade connectors, heat shrink and solder. its a permanent install so treat it as such.

Ok thanks guys , it looks like I'll have to get the arc add on to my up rev tune then to enable burnout mode

When switching off traction control and the installed yaw switch does the ABS light also come on, effectively shutting off ABS too?

Descriptions, drawings, schematics, etc are in the FSM (link in my sig).

Not that you shouldn't believe Gomer_110 (he gives good answers), but:
1) Everyone here is just Some Guy On The Intertubes.
2) The FSM is a great resource for anyone that does their own work on a Z.

I have the FSM; however, as we all know it simply doesn't tell the experiences of others when it comes to modding factory systems. IMO it's useless in my query.

It would tell you that the yaw sensor was not involved in the ABS system.

But, yeah, it's good to get confirmation from other members.

Most of the time at least.

No. You can cut the power to the yaw sensor and still retain functional ABS.

So that green wire is a pain in the *** to get to. Would it seem smart to insert two posi tap to the wire at both ends, then extend the wire to an on off switch. After that, just cut the wire in between the two posi tap?
