For guys that havent seen it happen in there cars, go to an empty parking lot, and floor it with the wheels turned (ala trying to do a donut) it will most definitely cut power and do it in a hurry, maybe its something with the torque vectoring system and not wheel spin

Yes, very true, I have had this happen once... wheel was turned pretty far... she just sat down until I let the throttle go... then reapplied with less turning... off I went. No wheels spin, just turning for that.  However, never had power pulled in a straight line except when i lost the LPFP and the car went into limp mod and then died.

Just brainstorming now, but maybe with the added power from meth, hes getting a little torque steer, and turning the wheel to correct and somehow triggering an oversensitive torque management system..?
 
Is this similiar to the same issue GAD had in the other post from Will3231? I thought there was nothing you could do with the tune, it was the TC system. Curious to know if Torrie can disable that. I know they used to do it in the 03-04 Cobras.

I don't think torque steer is an issue. It doesn't really have any honestly. My grasp on the issue is that when the wheels spin the stability/trac system will cut power for just a second in order to gain traction, which results in boost being dumped and power being lost.

It's happened on every tune I've had both with and without meth. Seems to me like it should be something that can be swapped / modified in order to stop it. I'll talk to Torrie but as others said I don't think it can be turned off with a tune.
 
I apologize for not reading the whole post but did you try ruling out a faulty speed/abs sensor,overtime from dirt and corossion buildup can lead to faulty readings which can lead to intermittent issues,by the wheel well if you can disconnect the speed sensor and use some electronic cleaner and inspect the contacts,also check the relays/fuses in engine bay to make sure there getting the proper contact,or try installing new relays for the speed sensor,inspect the abs module for any kind of water intrusion.Z
 
Wonder if it's a steering angle sensor problem...roll over protection cuts power when too much torque meets wheel angle variable?

Rich

 
Agree with Rich also,but these cars have a total of seven modules,one is the abs module which if found faulty or the related sensors will cut power by the ECU.Z
 
Mine is a PP and it has cut power a few times even with the system totally turned off. I am trying to understand what I am hearing at the end of the video. Is the car applying the brakes? When mine did it in the past it just disengaged the system and bounced off the limiter.
 
Right at 30 it doesn't brake it's just like as if I let off the pedal for a second (which I don't) and then it finishes off 1st gear without making boost. Then once second gear starts I get boost back and it's normal. I know this because my methanol light is on til that power cuts off and never comes back on again until 2nd gear. That means once it cuts power I make less than 8psi of boost (if not any at all) until 2nd gear comes. I can probably make a video of my rpm gauge too when it happens.

Wow! Thats pretty bad! Looks almost like you were shifting.....
What kind of tires were you running on that run?

If your referring to I, I have the Goodyear f1 supercars on her.
 
PP does it with traction off, well i will be mad at ford if that is the case with mine. i have not tested it yet. anyway you can  take it back to dealer for a reflash, and tell them that traction off button does not work? lol

I would do just that... You have the PP, and you can't perform!
 
Your "Cool Turbo Sounds" Sounds like surge from pluggin up your BoVs.

But the auto quality on that wasn't the best.

The bovs always worked (vented to atmosphere) until I started this tune. I'm assuming that it is within the tune because if i go back to my previous not methanol tune the bovs work every time and I don't get that high pitched reverse turbo noise. Either way it's not harmful which is why I'm not worried about it.

There's nothing in that statement, or in your OP I wouldn't be worried about.

This is also why I don't buy used cars.

All that aside. My tune is complete garbage for anything that's not wot. I can't tell if it's the actual tuning or the TCM freaking out over having more power at different places. I have half a mind to go back to stock because these platforms clearly hate extra power. I hateOBD2 Tuners.
