I know that Track mode has more interference than Sport mode. I'm saying when I'm in my custom set-up with transmission being in Track, suspension being in Street and traction being in Sport, I then hold the button down until it chimes and shows on the screen that traction is off, it still has the interference as I have previously describe. I wonder if it has added protections in custom mode even when you turn it full off? Do you think it is defaulting because the transmission is set in Track mode? This is not just about smoking my tires off, it drives me crazy when under hard acceleration while slightly turning. As soon as the car shifts gears it's like it goes limp a little (the car not me). I cannot be loosing boost in the shift to make it feel like it lost 300 HP until it gets full traction again.?.?.?
There is ONE thing that you cannot "turn off" that affects the power output the engine has. Yes, if the traction/stability if full off /disabled you can go hog wild doing donuts with a wheel speed of 130 MPH etc. But you cannot be
over revving and you cannot be approaching the rev limiter with the engine accelerating real fast. The rev limiter is predictive and looks at the rate of acceleration and will do 2 things to control RPM. #1 Pull Power, and #2 force upshifts. If the rate of engine acceleration is real fast the Rev limiter will try and get ahead of it. It will not let you actually get to the rev limit. Also if the Transmission is upshifting then the engine will pull power during the shifts. Maybe the difference in these 2 situations you describe is a difference in the traction available or a difference in the way you are applying the throttle. Here is a good example in my Demon. That car would annialate the tires in the right circumstances. Layed some really good stipes once in default with a conservative application of the throttle. But one time I was getting home and there were some Guys hanging out so I thought I would show off a little for them. I know I was in default but it still will spin the tires and leave marks in default. But this time it was wet and there were leaves and I was on concrete. I stabbed it to the floor and I had absolutely NOTHING. Just a stupid flutter. Well, it was like being on ice and you can bet the rate of acceleration of the back tires, the engine RPM etc were enormous.
This is the reason the car will many times force upshifts even if you have the shifter in manual.
The one situation you talked about cycling the ignition. That will put you back in default everything.
Also if the car is forcing upshifts in a low traction approaching over rev situation it may be doing one shift and if that is not enough doing one more and so on and that can give the impression that it is cutting power, and it is, because it is shifting. So if it is doing multiple upshifts it can seem like it is totally shutting down the show but rest assured if you left the throttle down long enough it will probably EVENTUALLY get with the program. I bet when it does this you end up just letting off. I would.
