As mentioned in a recent thread holding the traction button for 10 sec will remove any torque steer you are experiencing buy shuting off esc,

but esc (big brother) can save your azz in an unstable event. I know this threw personal expirence.

 

In my automatic I put it onto competition mode, hard on the brakes left foot, gas pedal to the floor and then when I let the brake off I really wish automatics came with a limited slip because all I get is wheel spin. Leaves way harder than anything else I've tried. Probably don't want to hold that for more than a few seconds but it feels like competition mode just loads everything but really doesn't open the throttle with the brake on. Which makes me wonder, does it work the same not in competition mode, never tried it?

Something to consider is that with the issue Toyota has had we may get laws that will prevent the gas pedal working while on the brake. An overide.

The override would kill two foot racers who gas and brake in a corner and brake torquing.

 

GM already sort of does that on many of their cars since the early 90's. The brake pedal is down, the throttle is down and the vehicle is not moving. They know what you are about to do and will "take the fun out" as they say. With the electronic throttle they could just ignore the throttle until you release the brake.

Yeah, I'll bet a law is coming for that. At least we are safe from lawn darts......

 

99% of all cars are not going anywhere with the brake on. The brakes will stop any car in the first application and over power the engine. The ones that can't stop usally have applied them several times and not one hard application. Once they get hot you may not stop then.

GM has not done anything accept with the drive by wire cars you can't really rev over 3000 RPM in part or neutral. My GTP with Drive by wire back in 04 was the first I noticed it on.

Now with it in geat all of my drive by wire cars it is game on and you get full throttle brake or not. It may not over power the brakes but the power is there.

I was just thinking of the Audi claimed stuck throttle that led to the shift interlock on all automatics today. There was one that hurt Audi but it was found later to be driver error. I never saw the press correct their error on that one.

 

I think you missed my point. It's not about the brakes being overpowered, it's about the ECM knowing that the combination the brake being applied while the throttle position is not 0% and you aren't moving can mean only one thing -you are intending to do a burnout (power braking).

GM in fact did have a subroutine in the code that would watch for throttle and brake pedal down at 0 MPH and take action. I know because I hacked the 88-95 SC PCM code and it was clear what they were doing. They would also give you up to 25 second of fun and then start to pull timing and bypass the SC ("Now Take the Fun Out" is literally in the official code listing.)

I don't know if they still do it since I no longer hack much code (the last thing I did was the 95 6.5L Turbo Diesel late last year), but they aren't stupid. I've seen the early official 3800S2 code long before HPT and everyone else got into it and GM was still watching for what they deems as abuse and would take action.

It interesting they provided the Launch Mode but you can bet torque management is engaged heavily.

Either way, this is disintegrating into a did too-did not discussion. I will leave it to the rest to work out comp mode. With electronic throttle they can just not read the pedal position and leave you sitting there.

 

I keep forgetting I have competition mode. When I remember and use it on occassion, it's like Christmas morning all over again. :)

 

I do believe that is called a TRANS SLAM which brakes expensive parts don't do it.!
