Engine braking doesn't magically give you more traction than using the brake pedal. You're still putting resistance to the ground through the tires
That's right, but the engine isn't trying to bring the wheel to a complete stop, like the brake calipers are. If an engine-braked wheel slips, it might lose a few MPH until it regains traction, but it won't lock.

You do realize there are infinite positions on the brake pedal between standing on it with all of your weight and having 0 pressure on it, right?

Actually, there's a beginning (rest) and end (planted to the floor) for the pedal. So infinite is not correct.

If we're still beating this dead horse..

Infinite is correct... A CVT has an infinite number of possible ratios between two set points. A line segment of any size has infinite points on it. There's an infinite amount of numbers between 0 and 1.

Like I said, infinite is correct.

edit: In case you still don't believe me https://en.wikipedia.org/wiki/Contin...e_transmission "...is a transmission that can change seamlessly through an infinite number of effective gear ratios between maximum and minimum value." and if you actually needed that to be convinced, maybe take a middle school math class.

You said infinite in regards to brake pedal positions.

Really though? You can't read my post that's right there? Talk about lazy

"infinite positions on the brake pedal between standing on it with all of your weight and having 0 pressure on it"

I did read it.

You directly said about the brake pedal. So wherever the CVT argument came from, I don't know.

But you won the internet. It's been real. Subscription removed.

Understood, but the calipers are trying to bring the wheels to their own speed (stopped).

Regardless of how much or little pressure you apply to the brake, the instant caliper to rotor friction exceeds road to tire friction, your wheel will quickly stop as the car continues moving.

A wheel under engine braking does not behave the same way.

Well in reality, at speed, there's 0 difference to the tires whether you're braking lightly or engine braking. At low speeds, yes there would be a difference, but not much.

In reality, if what I described happens at any speed, your wheel will lock. It's why ABS works at all speeds.

The whole reason ABS exists is because of people (apparently like you) that can't regulate their braking so their wheels don't lock. There is 0 difference to the tire whether you're braking with pads or the engine unless you press so hard on the brake that the ABS needs to activate. The only difference is brakes are designed to stop you so they apply force much more evenly and efficiently than the transmission would. Engine braking is just a side effect of having an engine, no one except turbodiesel heavy duty truck makers specifically make their engines brake efficiently.

ABS/VDC exist because they can react faster than any human and can brake the wheels independently.

What you don't seem to understand is that available traction fluctuates wildly and varies from wheel to wheel.

You cannot brake the wheels independently.

You cannot tell with certainty which wheels (if any) have locked.

You cannot respond to a locked wheel in 1/20th of a second.

You cannot use the brakes to direct power.

You cannot reduce braking force to a locked wheel without reducing braking force to the others.

You cannot use the brakes to correct the orientation of the car.

ABS and VDC do all of these things.

I'm writing this mostly for others who might consider your bad advice since you seem hell bent on wrecking your car.

And you think engine braking somehow fixes those problems? That's so unbelievably stupid that I'm done talking to you.

I said no such thing. Read again, this time for comprehension:

My post about ABS was in response to this:

Driving skills aren't a substitute for ABS (or good tires).

Engine braking is just another tool that's useful in winter driving.

The car does behave differently slowed through 50/50 open differentials than through the brakes.

Using engine braking together with ABS helps regulate braking force and wheel speed vs braking alone, which is why I suggested it to averagewhiteboy.

Default VDC installing

Hello from Prague, Czech republic.

In contrary to you I have another issue. I would like to INSTALL VDC on my Impreza MY08. But unfortunately I am not able to find any "DIY" guide.
Do you have any idea if it is possible or not?

It is probable, that a lot of wires, switches and other stuff are already there.

Thank you for your response.

Pavel

would be better to create a new topic as this is about the MY12 and newer cars.
