Very nice video, Steve.

tc off

 

Try sliding easily around a corner with just the traction button pressed and you will find the ESP kicks you into touch.

You missed my point, hard launch in a straight line and the crossfire nose dives even with the traction off.
This thread isnt just about just spinning the back wheels its about being able to do things with your car without it stopping you mid stream.

stevieb , sorry about picking you mod apart. I didn't see or read about any relays in your instructions for your mod, and i just wanted to put it in the thread so if any one else tries this they will be doing it correctly and some what safely.

 

No problem.
You were 100% right, my fault for not pointing it out.

By the way will post the video of switches in action as soon as it stops raining. Great British weather!!

On my srt 6 i just disconnected the esp-and tc wire in the little box in front of the batt. I had to try and see if this would help me at the drag strip,
burn out # 1 about 3 to 5 ft and then went like hell============
held the brake ,it spun for about 10 ft the felt like it bogged not sure so i did that one again, repete spun for about 10 to 15 ft and car went like hell,
repete this with my foot on the brake and with our the brake everything was good.--------------------------------------------
Then i was looking for water to try it ,,no water, but i found grass, wet green grass . --------------------------------------------
spun 1 gear 6000rpm,2 gear 4000 rpm, and held that for a few seconds,,,,, then moved to blacktop, stoped ,wot took off spun about 5 to10 ft and car took off fast. had to repete that knowing the tires were wet, this time on the black top took off holding the brake spun,fishtailed but went like hell, went back to the grass and this time spun through 2 gear into 3 gear all looked good, slowed down then pulled on the street made a right turn and no supercharger,, all these runs were made in 10 to 20 min so i wanted to see if it got hot and shut down,, went about 3 blocks pulled over and shut down the engine, restart, every thing back to normal, made three more dead stop ,,,full throttle , and two more holding the brake and then at 1500 letting the car go so as far as i can see it will work. next i will try it at the track. total time from leaving my house driving to a main road and doing all the burn outs and back to my house total 25 min, jim

 

Would you mind pointing out what wires you are getting into behind the dash for the esp?

 

B.S. I have no teenage obsession with burning rubber, nor do I have an unfulfilled fantasy to do donuts at my neighborhood K-Mart parking lot.
What I do have is a desire to be able to get my car to do what I ask of it, when I ask it, and not have "Big Brother" making my driving decisions for me.
On three different occasions over the past 3 years of ownership, my car (thanks to the "black box" over riding my throttle input") has almost got me wiped out (by on coming traffic) because the car decided to go into "limp" mode at the most inopportunistic moment, simply because the rear tires broke loose ever so slightly. Possibly, the TC on the 04's (like mine) is a little more sensitive than the 05's, plus mine is a 6 spd.
After disconnecting the center wire and losing the ABS/TC, my car hasn't shut itself down once. It's a much more "fun" car to drive now, and I can actually break the rear end loose when ever I want to.
I don't drive it in the winter, and only in the rain when I get caught in a storm unexpectedly. I've never been a big fan of anti-lock brakes, and actually have had more close calls in some GM cars that had them, than any car that I've owned that didn't.
I'm not recommending that anybody disconnect their ABS/TC like I did, but for me it was the right thing to do.

 

Wires for ESP are not behind the dash but located under the center consol behind the gear shift.

Thats where you will find the yaw sensor that controls ESP.

Steve

 

Do you remember the colors of wires or pinouts on the yaw sensor?

 

I just installed my switch from the wires in the engine compartment and unplugged my yaw sensor, but I can't figure out how to hook my yaw sensor up to a switch, there are several wires connected to it and I don't want to cut them or anything without knowing for sure what i am doing. Can anyone tell me how to connect it?

Here is the switch I already installed, the yaw switch is going to be identical on the other side.

 

Here is a diagram of the sensor. I'd start by seeing what happens when the +5V sensor supply wire is disconnected. If that doesn't work, next I'd disconnect the steering angle signal wire. I don't know that I'd do the mess with disconnecting the sensor ground wire since it will probably still find ground through the chassis. Hope this helps and let us know how it works.

 

Thank you for the diagram, I"m probably going to try it tomorrow so I'll put pics and results up as soon as I'm done.

Also does anyone know if it has to use 50 amp switches and relays? I used a 50 amp switch but there is no relay on it as of right now because I could only find 30 amp relays at my local auto parts stores. I'm going to order 2 50 amp ones online, but I would like to know if it would be safe to use the 30's.

 

What are you using the relays for? If it's a 50A fuse that you're tying into, your 30A relay isn't large enough to handle that load. It might not always be that high but they put that size fuse there for a reason and if they could have gotten away with a 30A, they would have.

 

Right now I have a 50A rated toggle connected to the Hydraulic Unit(Traction) wire, I guess what I'm asking is do I need a relay at all or is the 50A toggle enough by itself?

Also, I have an identical 50A toggle for the yaw but I'm not sure what the amps would be on the yaw sensor so I don't know if I even need a relay for that either or if I do, what size it would have to be.

 

Keep in mind when you disable the hyrdaulic traction unit under the hood you lose your brake lights as well, i was really dissapointed when i found this out. but taking out the yaw sensor does disable stability program just not traction, which was perfect for me.

 

that's weird, I still have brake lights even with both switches engaged

 

My brake lights still work with everything disconnected, maybe it's just varies depending on the year of the XF. Mine is an 04.

 

Ok, It took longer than I expected... maybe because I'm lazy, but I finally got my yaw switch hooked up.

I still don't have the switch mounted because I have to borrow someone's drill for that but all the wires are hooked up and it is functional.

The red wire is the one you have to cut into to hook up the switch. it is labeled as #3.



here is a pic of it hooked up



I apologize about the quality of the images but the only camera I had to work with is my cell phone.

 

All,

Has anyone taken their car to a shop to have them disable the TC/ESP using the MB star software?

I just got off the phone with a particular Crossfire Tuner and he said it couldn't be done - as it is wired into all of the control modules in the car, but I have heard others say it could be done using MB star software.

I tried pulling the TC/ESP fuses and the car absolutely screamed for a couple of launches and then promptly went limp.............into limp mode that is.

I am also not out to do stupid teenage tricks with it, but I do not like the TC/ESP. That is all I am going to say there. Please do not post the benefits of TC/ESP. We can save that for another discussion.

I would really just like to know IF someone has disabled it using software, and did it go into limp mode afterwards?

Any info would be greatly appreciated!!!!!!!

Thank you all!
