Heel-and-toe down shifts

[KNS]

New poster here - seriously considering a BRZ next year. I did a search and really couldn't find an answer... Unless I searched the wrong key words.

I've read that when you apply the brake and the throttle at the same time, the car will cut the throttle as a safety feature. I suppose this is a result of runaway Toyotas and owners not being able to stop the car - which is a whole 'nother subject.

My question: If you are trying to downshift and want to blip the throttle with heel-and-toe technique, does the above feature prohibit this?

I've driven manuals only my whole life and my current car is very easy to heel-and-toe on down shifts.

Thanks. Great forum you guys got here.

BRZ is easy to heel and toe downshift. If somebody tells you otherwise, they don't know how to heel and toe downshift.

Thanks for the reply, nice to hear that it's an easy car to heel and toe. But, I take it the throttle does not interrupt while pressing the brake and throttle at the same time? It says so in the brochure I'm just not sure to what extent.

Should have checked it on my test drive.

ive never had a problem with the brake shutting off the throttle during heel-toe. mines a 13'.

I've never even heard of this before, where did you read this?
But no, the throttle doesn't cut off when pressed simultaneously with the brakes during heel-toe.

No problems when I make the downshifts.

Says so in the 2015 brochure: 'Brake Override System'

"If both brake and accelerator pedals are pressed simultaneously, the system reduces the operation of the accelerator pedal to help prevent unintentional vehicle acceleration"

I imagine the lawyers came up with this one after people were unable to stop their Toyotas.

It does, but it's not instant. It takes a few seconds, I believe. This doesn't affect heel-toe shifting, and shouldn't affect left foot braking as long as you're doing it right. It's good for people that panic and hold both pedals at once.

This is only if the car is in gear. You can rev the engine all you want with your foot on the brake as long as a gear is not engaged.

If you try and do a brake stand, use the brake pedal while drifting, or brake boost (if you're turbo'd) you will feel the engine start to cut power. Unless you do the pedal dance that is.

Thanks guys, yeah, I was wondering if the trans being in neutral (for a second) factored into it.

No not at all, I heel-toe all the time!

The heel/toe downshifts work great in the BRZ.
Only after the ecu finishes it's 100km of learning.
So if the ecu is reset/battery disconnected it goes back to learning.
During learning the ecu causes sluggish throttle blip.

I had an NC Miata and heel-toe downshifts are significantly easier on it than the BRZ. I find that the BRZ's gas pedal placement relative to the brake pedal is higher and further apart than the NC's. With the NC, I use the left side of my right foot to brake, slightly rotate my foot so that the right side of my right foot can blip the throttle(AKA lazy 'heel-toe'). But with the BRZ, I really have to rotate my foot to blip. The BRZ takes 'heel-toe' literally. I have since then installed the Cusco Sports Accel Pedal, and it's definitely made heel-toeing much easier, and quicker. Just like it was on my old NC.
