yes it is also on manual cars, i tried it myself. and yes, you can still heel and toe just fine, i tried it myself. i don't know how it happens but i'm guessing maybe pushing the clutch pedal overrides the throttle cut off.

Can heel and toe for sure, but I'm not sure what happens when the clutch isn't pressed.

But uhh, here's a picture of the start of the corner. I went back and checked out where it all happened. I did NOT nip the corner as I first thought. It was my only logical explanation as to why my TCS would have lit up. So, now I'm completely clueless to be honest.

Coincidentally a grounded power line right there. But, I have a hard time believing it's the cause myself. We'll find out soon

The wheel spin sensors aren't that shielded from EMI - maybe they're feeding bad data...same with the gyros in the car which tell it which way the driver is intending to go vs where the car is heading.

i donno, some times people think they are on the brakes while they are hitting the gas while they smash into stores and poles and crowds of people.

Just out of curiosity, what's your source of that info? Since the Toyota debacle, I've been wondering whether or not the 370Z has a brake override.

Just Google it.

Per After Toyota Troubles, U.S. Weighs ?Smart Pedals? in All Cars - NYTimes.com

The override system is meant to deactivate the accelerator when the brake pedal is pressed.

Often called a “smart pedal,” the feature is now installed in many automobiles sold worldwide, including models from BMW, Chrysler, Mercedes-Benz, Nissan and Volkswagen.

Nissan Motor (7201.T), held 44 percent by France's Renault (RENA.PA), is the only Japanese carmaker that has a function on nearly all of its cars that prioritises the brakes when both pedals are depressed. This excludes 660cc minivehicles sold in Japan under the Nissan badge and cars produced by other automakers on an original equipment manufacturing (OEM) basis.

Gotcha, but I'm wondering if there's anything documented that the 370Z has the override. I would think that it would be mentioned in the Users Manual if the Z had it, but it's not (as far as I know).

Yeah I don't recall seeing it mentioned in the manual, but FWIW, over in this thread How to launch control with A7 370z? I've seen it mentioned that you can't launch the 7AT by standing on the brakes with your left foot while depressing the throttle with your right due to the override.

I don't know if thats really a brake override. You can't rev the manual in neutral over a couple thousand rpm either, brakes on or off.

Sorry to read about this. I have the exact same setup as you, but my car is an early build. I've never had an issue thankfully.

I could redline in neutral. That I'm sure of. You can't?

When making a video with my Berk exhaust we hit the limiter, that was the first I had ever seen of it.

semtex · 03-28-2010, 07:46 PM

Mine revs to 4k in neutral, if I remember correctly. When I made my exhaust vids (the stationary ones) I had to put it into 1st and keep my foot on the clutch to rev up towards redline.
