Disabling Advancetrac for autocross: Pulling the ABS fuse? Anyone actually try it?

I know this topic has been beaten to death..

I've searched and read over and over about how the the Boss 302r/s module is the end all for solving the advanctrac intervention... I get it, it solves the problem and improves abs function with slicks as well as brake bias for track use.

Regardless, I'm looking for other solutions to the advancetrac dilemma for my S197 as it serves primarily as a daily driver that sees frequent autocross use. I just cannot fathom commuting in the car with the chimes on the dash lights going off as I sit in NYC bumper to bumper traffic everyday on the Cross Bronx Expressway. Yes, I could swap the modules out multiple times a year but I'm hoping there is a better solution for my purposes

Last year I had some success with cycling the key between runs, but this was imperfect and still resulted in advancetrac interference at times. Seeing how I had these issues with a 265 width 200tw tire, I'm predicting this situation will be exacerbated with 315 width 200tw tires. I would like to have my cake and eat it too with abs/advancetrac on the street and the ability to disable advancetrac at weekly autocross events

What I've seen as alternatives but would like more info about:

- A "track" tune which disables advancetrac like from AED: Unfortunately, having a 3.7 car Shaun will not tune it and no other tuner seems to be willing to write a track only tune for the car (I've called 6-7 shops). Does anyone have a lead on other tuners who have a good track record of doing this?

- Pull the #5 pin from the factory ABS controller: Saw an old thread on SVTPerformance mentioning this but the diagram/how-to was taken down, it has also been mentioned in passing on this forum without any concrete info. Does anyone have any real experience with this? This seems like an interesting way to retain ABS on track without advancetrac, then put everything back to stock for street use.

- Pull the ABS fuse (#34 IIRC) for events: Far from the ideal situation. I've autocrossed NA Miatas and CRX's without ABS, I'm aware I could lock up tires a which can shorten their life on a heavy car like the mustang. I would certainly imagine missing functioning ABS much more on a road course than at an autocross. Does anyone have ACTUAL experience autocrossing an S197 with the ABS fuse pulled?

Additionally I've heard rumblings of people putting a switch on the body control module or removing the clock spring to disable advancetrac, but nothing finite about whether or not these will achieve the results I want

If push comes to shove I'll try the ABS fuse pull myself with last seasons leftover tires as an experiment, if that doesn't work I will break down and buy the Boss 302r ABS controller and deal with the chimes/lights for the spring & summer months

Appreciate any input or insight as always!

Not sure if this is the same in a v6, I'd imagine it would be, but on my GT there are three buttons near the gear shift. One of them should have the traction control symbol. If you turn the key 2 clicks, so one away from "ON"( I believe that is the right setting, the car may have to actually be on. Sorry, been a while since I did this last), and hold down that traction control button for 10 seconds, it should pop up a notification on the dash saying "Advancetrac Off", or something of the sort.

Not sure if that is what you're looking for exactly, but it does most definitely get rid of a LOT of the electronic assist, and you don't have to spend any money or pull anything.

Thanks for clarifying, we definitely have been holding the button for the full 10 seconds until the message "Advancetrac Off" appears. Unfortunately when the car gets loose or has too much slip angle, it reactivates and intervenes
 
Might seem like a longshot, but it seems heat from the over-axle tubes may affect the TC's wiring loom as far as S197s are concerned:

One more thing to consider - the 302S/R ABS module is a very simple install and easily reversed. Just pull the CAI box and then 4 torx screws to swap. The exposed electronics are sensitive, but shouldn’t be an issue if you swapped back to street module on Sunday night in the garage. Just a thought.

I've read where other cars can re-activate their stability control systems under various circumstances, but this is the first I've heard about a S197 Mustang being involved.

Makes me appreciate my '08 GT all the more.

I've changed out the ABS module several tymes and it's not a difficult job. Maybe a half hour if you move slow like me. Had to remove it here because it would never get through inspection with the lights on the dash lit up with the 302R/S module.
 
Another option is to disconnect the yaw sensor, you will still retain ABS but not stability, it's relatively easy as it's under the console, one could even rig up a switch to interupt the 5v reference signal to it to be able to do it on the fly. But the top of the console comes off so easy with no tools it's so easy to pop it off and see it right there beside the e brake. This will also cause all sorts of lights when it's disconnected but for the track it doesn't matter to much. On another note I haven't had mine reactivate on me, as the stabilitrac light off symbol stays on throughout the run.

I have looked under the console, but obviously not hard enough, and cannot find this yaw sensor. I only see what appears to be an air bag module but nothing else. Would model year dictate where it is at? Mine is a '13 s197.
 
From what I can gather, the yaw rate sensor is built into the Restraint Control Module. As stated earlier, this is found inside the console.

The following is from Alldata for my 2012 Boss :

Stability Control Sensors
The stability control sensors for the ESC (Electronic Stability Control) system include the yaw rate sensor and the lateral accelerometer. The yaw rate sensor and the lateral accelerometer are able to detect and measure changes in vehicle direction that indicate the need for the ABS to make corrections that help prevent vehicle roll over or spin outs. The sensors are housed in the RCM (Restraints Control Module) which sends sensor information to the ABS module over the Controller Area Network (CAN).

Excellent follow up sir! I will give it a shot in a weekend or two. So far on the track it has not reactivated even in ~30 degree corrections at ~50 mph. I would like to keep it that way, especially on track with walls! Cheers.

Well, I have bucket seats so side airbags are out anyways. From what I gather, having a harness and hans makes front airbags useless as well. The 'stang is turning into a track machine as well.
