The ebrake switch diconnnects the rear so it can freely lock up without damaging the drive train.
That is the only thing it does.

 

The x reads speed from each wheels individually. through the abs system.
Either you need RS stock engine ecu or an aftermarket one to disable the abs. Any other way your awd system wont work. It will work only kind a like a limp mode.

 

Here's the link evofan posted earlier

 

If you're just looking for more oversteer, there are plenty of ways to get it without completely disabling ASC / Traction control. Get a strong sway bar + endlinks. <-- this has worked great for me. I got Perrin's bar and put it on the middle setting. I can kick out whenever I want. Put it on the strongest setting and I'm sure you won't have any issues.

 

I know that you know how it works, but the way that you said it might confuse some people, so please let me restate it.

The only effect on any part of the S-AWC system on a GSR of the e-brake switch being activated is that the ACD (center diff) snaps to wide open. I have no idea if the SST of an MR opens a clutch when the e-brake is pulled; I assume that it does [why? because rally car!], but no-one with an MR has let me beat on their car (yet) for testing.

Most of all (for this thread): the e-brake switch has no effect on either type of traction control.

 

Does anyone else who knows how the S-AWC system works find that video annoying? Knowing the effects of a certain change to the settings (on one particular driving maneuver) is nothing like knowing the actual difference between the settings.

Let me put it this way: each time someone reposts (tritech!) that video, Tommi Mäkinen kills a kitten.

 

Another trick is being aggressive with the trail-braking (like you hadn't yet come to grips, as it were, with how much better an Evo is than a 2G DSM). I had no problem drifting every pin-turn in a bone-stock GSR at my first autocross in the car. The only problem was that I destroyed both rear Advans in about 10 minutes of seat-time.

 

Ouch!!!

 

Well, part of that was due to the ridiculous amount of rear toe-in that these cars have from the factory. That helped kill the tires. But none of it bugged me too much. The R-S3s were a half-second (or more) faster than the Advans.

"Honey, the rear tires on the Evo are dangerously bald. We have to buy new tires now, instead of the end of the season. After all, I drive the kids to school on these things."

 

I have a set of scrub Eagle RS tires I want you to try. Think of a slightly stickier R6 with better wear.

 

thanks , and yep .

the MR E-brake does a same thing.

 

I just picked up my X today, but it currently has no engine.... so I can't do any definitive tests for a while yet. Reversing the position, or simply jumping the switch wires would be easiest, but I have a feeling it wouldn't work. If someone would care to try holding down the switch continuously while the car is off->starting->running we could know if this is possible.

I anticipate needing to make a timed relay that only activates once the car is running.

Regarding the ABS, I think cutting one of the wires which goes to the actual pump motor and sticking in a dummy motor or resistor might have the desired effect of killing the system without it knowing. This will be more of a challenge. An RS ECU would be great.... if it could be found.

 

you can find RS ecus easily. Usually the RS Evos sooner or later getting ECU upgrades and there for the stock ECU's just laying around doing nothing...
But i dount it would be cheap. But still much cheaper then an after market proper ECU.
Cutting wires wont work. The Ecu will detect it.

 

You would also have to fool the system into thinking that there was pressure in the ABS reservoir. Otherwise, the system will detect that the pump is not working and shut down the ACD and AYC, as well as the already-not-working ABS and Type-2 traction control.

 

anyone know of a way/ find a way to have the car *remember* what "state" the ASC button was in when the vehicle is shut off then turned on and started again?

ie- if i had the button off-off and then turned off my car and then turned it on again, the ASC mode would still be off-off. and of course same for the button just pressed once to "off".
