You could always test it if you are on really good terms with the dyno operator.

Jack up one side a little for a pull until one wheel starts to slip.
You might be able to hear the ABS system actuating and see the response in the dyno data. (small step function in torque when it applies brake)

Bad idea. The pedal dance (Inspection Mode) exists specifically for chassis dyno safety.

HINT:

If Inspection Mode is not used, the vehicle may unexpectedly move off the dynamometer because of TR(A)C and VSC operation.
The VSC OFF switch must not be used to disable TR(A)C and VSC operation when the vehicle is to be operated on a dynamometer. Pressing the VSC OFF switch does not disable TR(A)C and VSC operation completely.

Of course I know that.
It would be for "engineering evaluation purposes only".
Do Not try this at home
This test is being performed on a closed dyno by professionals
We cannot be held accountable for any property blah blah blah.

It would still be an interesting test.

One of those F1 car test rigs would be fun to test our cars to explore the behavior of the various VSC, TC, ABS, EBD, & EDIFF modes.

Haha... Well, if you put it that way...

Didn't do the pedal dance to tune my 15 or my 17 - shrug.

Without eyes on the source or at least a solid functional diagram that text is no more than a liability disclaimer. Intentionally lifting a wheel to see the effect is a different story. I'd hate to read about a mishap because someone actually tried it.

@CSG Mike, can you comment on the acceleration/torque between an e85 with Ace header tuned BRZ vs a stock 2015 WRX? What about a 91 tune and a WRX?

CSG Mike · 12-01-2016, 05:04 PM

Turbos make torque.

That's not a comparison I've ever had the opportunity to make, beyond a dyno.

CSG Mike · 12-01-2016, 07:58 PM

Because Laguna Seca.

And CSG's Laguna special is not ready yet so I can't buy one.

Zero rattles with stock front pipe. Awesome.

Thought you have both vehicles. Can a tuned BRZ keep up with a stock WRX on the straights?

I don't know; I haven't tried.

Header stage2 e85 frs was neck to neck with stock WRX from 20roll all the way to triple digit, then wrx started to pull slower then my mom riding bicycle.

This was at Mexico of course

Sure, although I can't promise anything spectacular!
