i dont know anything about ABS system being bypassed... dont think it can be done

engine braking would help slow the car down

if the clutch engagement is NOT smooth (yanking), then that WOULD induce a slide and exacerbate the situation

 

I usually throw it in reverse and feather clutch to slow the car down. Reverse lights really wreak out the drivers behind, and I saves the brake pads wear. Also car isnt coasting so cops cant give me a ticket.......... j/k

 

Well, I guess I don't mean bypassing, I mean just not activating ABS.

Since you would be reducing tire speed without pressing the brakes, ABS is not doing anything.

So, if the tires start to break loose on ice (or any surface for that matter) as the vehicle slows, ABS will not kick in during an engine brake. This would be true from fresh rain, standing water, road contaminants, and bad tires. I can see scenarios where engine braking would cause loss of control vs. ABS could retain the control...not in all cases but in cases where the tolerance is close enough ABS to keep the vehicle from breaking loose from the road surface.

I understand that we can rev-match, and engage the clutch slowly, but even then, it would be hard to replicate the effects of ABS which makes adjustments up to 15 times per second.

 

I haven't lived in an area where there was ice for over 30 years, and 30 years ago I drove quite differently than I do today. On ice, I'd throw the car sideways as I approached a corner or turn, and then modulate the power to alter my course. It's like drifting, but at low speeds and in slow motion. We use to get out on lake Huron in the winter and slide the cars around at higher speeds. Ice can be a lot of fun when you are young and immortal.

We've seen more than one crash due to a bad shift while cornering in the rain and the situation is much worse with ice, so BE CAREFUL guys. Driving on ice requires the same kind of smoothness that it takes to drive flat out on the track.

 

You are correct. The ABS won't stop the slide that is caused by shifting. It also won't stop you from sliding off the side of the road if you nail the brakes mid-corner. It has no bearing on anything other than the application of the brakes, so other forces (cornering, engine breaking, etc.) can still cause a loss of control.

Traction control systems don't repeal the laws of physics.

 

[QUOTE=RED MX5,Jan 15 2007, 11:30 AM] You are correct.

 

oh, i definately didnt endorse using engine braking as a substitute for the foot brakes. it should be used merely as an "aid" as so not to rely Solely on the foot brakes (when there is lessened traction due to conditions)
