Why did Nissan wire the car so accelerator cuts when you have foot on the brake? Is there a known hack to disable this electronic nanny device? Makes it hard to left foot brake on the track!

Not sure why. Members have been asking this question for 8 years. Not a new subject.

Hmmm .....searched brake boost and didnt find anything very clear on 370z?

Shamu

Still not finding much?

Most likely engineered in to avoid liability issues. In a society that blames companies for unintended acceleration, legal departments have a lot of influence into things like this. But I road race my 350Z in SCCA and haven't noticed much problem with it- but then again, I'm primarily a right foot braker...

So is this true only for the 370, or does it happen in the 350 also?

350 does this too

The "power start" or "torque start" is a popular subject in the 350Z drag racing forum. It is a trait of the automatic transmission. Members remove the brake light fuse for drag racing.

I assume this is similar for the 370Z.

Been driving a 350Z and 370Z for 7 years. Do not recall braking and accelerating at the same time. Why? Is this some sort of cool heal-toe thing?

Why???

Have you heard about the alleged issues with Toyotas?

Don't you watch the Nissan advertisements? Here's one that specifically mentions the fact that their cars have had brake override for six years.

One is GO the other is STOP, no need to use both at the same time.

What is this? Obvious day at camp stupid?

God I hope you are being sarcastic.

How long are you on the brake for this to happen? It doesn't pull throttle when I'm using my super cool 380RS pedal to pretend I can heel-toe. Does the 380RS pedal fit 370?

Since there's no mechanical linkage to the accelerator pedal, move the pedal assembly to the brake pedal. You'll be able to modulate the accelerator pedal angle with your foot at the same time you're applying pressure to the brake with your leg.

It'll be similar to using the combination rudder/brake pedals in a light plane, except you'll only be doing it with your right foot.

Ideally, an extra accelerator pedal would be mounted on the right side of the brake pedal and slightly lower. That way, you could move your foot to the left to step directly on the brake pedal for hard braking, and use the extra pedal for heel-and-toe work. The regular accelerator pedal would be used for normal driving. You could rig the electronics so whichever one was not at idle position would be sending the signal to the ECU.
