No sir you did not.

But we were talking in this thread about heating up your tires for dragging. So when you say burnout in the context of this thread I assumed you were talking about standing. No one said anything about not being able to spin the tires once VDC was turned off.

I jumped to conclusions based on the direction of the thread.

how far down the page did you go to find that picture? most popular result per google for burnout

The first 6 pages of images are all either the typical standing burnout or screenshots from the videogames

Also the first sentence of the wiki for burnout says GFYS http://en.wikipedia.org/wiki/Burnout_%28vehicle%29

By the way no hard feelings just F'n with ya

(Glad I wasn't in the front taking pictures).

When I posted my first reply here at this thread it was to gain information that would help me configure my car for the drag strip.
A specialized racing environment...Just needed to get my car to work better and get down the track faster.

My intent here is to understand my car better and maximize it's performance ... Modding it to do just that.

I've gotten a lot of helpful information (and have made some new friends) here on this thread and on other threads as well...

In my opinion this thread shows the passion, personal involvement, expression, and enjoyment that is typical of Z drivers.

Now on to the Semantics :

The phrase 'Burn Out' to a drag racer means something totally different than it means to a street racer.

Drag Racers lock the wheels and spin the tires - and go nowhere - all to heat the tires to create traction from a standing start. ...it has a definite purpose that affects straight line acceleration from 0 mph.
The Z's inherent limitations restrict the ability to do this.

Street racers and drifters on the other hand don't need to do this.

Either way it results in buying new tires ... but we all do need to be safe when we Flex the Muscles of our Z's.

About Performance / Why we need to Mod : and why we ask our peers

The Z is a well engineered reasonably priced sports car but lacks flexibility ... it's just not in he same category as a high priced super car that has a lot of set up options.

Super cars have a ton of user adjustable settings that allow you to set the car in different modes depending on an individuals preferences,driving style, and road or track conditions at will.

The Z only has a few stock user control/adjustments available ... and the engineers have purposely designed the car so that (hopefully) it won't hurt you, you won't hurt it, and the general public won't get hurt either.

In other words ... the car has a number of built in safety limits that are intended to benefit the majority ... at the cost of maximum performance.

Some of these safety limitations however can impede the performance of the car in a racing environment...or even just spirited driving.

About Maximizing Performance : Why we do this

As racers and enthusiasts, we need to find workarounds for some of these limitations when they interfere in order to maximize the potential of our cars.
This is why we ask questions.

There is always a trade off that we need to understand and accept when we do this.

There is also more responsiblity involved when we modify our cars outside of it's original design intent.

Bottom Line ... we all share that Need for Speed ... a loosly knit Brotherhood of sorts.

It is Good to Burn Rubber ... But NOT Friends

Totally Awesome .... cough cough

This sez it all ... pls disregard my last post !!!

Thinking about this some more today. You guys will have to be careful when using your cruise when that wire is cut. Its no longer going to know to kill the cruise when you tap the brake which means if you forget or if someone else is driving your car and is used to killing the cruise with the brakes (like myself) you could be in trouble.

Just a caution I thought of today while driving a sweet rental car in West Texas. haha

I wouldn't be surprised if the cruise control just failed to work at all with the ABS controller dead. Be interesting to see what happens

Actually the cruise control is on a separate brake switch circuit. there are two brake position switches one for lights and vdc and one specifically for cruise control.

Also I did some digging through the FSM for you and found out (in theory) how to bypass the brake switch while still keeping your lights.

Its a bit hard to see but you essentially want to cut the wire going from your fuse block to your ABS controller. This will kill and brake signal going to your CanBus but yet still let your brake lights function as they should.

Again hard to see but the ABS connector is E41 and its pin 30 with a SB color of wire. Knowing first hand how hard it is to get to the abs connector I would probably look at the fuse block end of things (pin 1F of E103).

Hope this helps! I might do the same thing come summer.

Hey Mitch ... !!!
Car is in the shop right now and we are at the point of decision as to how to best nuetralize the VDC and ABLS when I go to the track...and then return the car to 'Normal' for driving on the street.

There have been some changes (or adaptations) along the way as the build has progressed...

The research and info that you have provided has been invaluable.
The shop has make the final determination as to the ease, effectiveness (and cost) of the modifications now.

I downloaded the FSM ... yikes !!! there are a ton of individual PDF files ...
Where can I find these particular diagrams ???

Just wanted to thank you again for your eagerness and ability to help me with this... AWESOME

Will keep you posted as to the results !!!

Bob

I would bet that the ABS would be disabled as this is what occurs when pulling the fuse for the whole circuit.

Hey Again Mitch !!!

Apologize profusely and muchly ... have so much going on in my head with the build ... couldn't find this info and that you already answered my question ...

Keep in touch with me ... THANKS

Bob

dimitarm · 05-27-2014, 02:54 PM

can somebody help me find the actual (pin 1F of E103) located at the fusebox so i can make switch to turn on/off the abs.

thompsontechs · 08-19-2014, 01:06 PM

Sorry to drag this one from the dead, but I had a concern here and wanted to ask you guys about it. I have a switch to disable yaw and I like it that way unless it's raining. I know it's basically an accelerometer, my concern is whether or not doing this might disable airbags?? If so I will rethink. I am thinking not because the airbag lights are not lit, but just wanted to make sure...

Thanks in advance

wstar · 08-19-2014, 02:01 PM

No, the yaw sensor shouldn't affect the airbag system at all AFAIK. The yaw sensor's hooked to traction control and ABS, but not to the safety system. There are impact sensors around the car that do that.

1slow370 · 08-19-2014, 03:32 PM

yeah the airbag system is entirely separate from any other system on the car, the NHTSA demands that it be separate so that a failure in one system cannot affect it's operation.
