I don't know what's with the flood of comments about how it's "dangerous" or "stupid" to drive on the street with ASC turned off. I am an experienced driver with quite a few track days and autoxs under my belt, and I don't like traction control; I can control a car under powersliding conditions just fine and don't like the ecu getting in my way. When putting around town, the car isn't driven aggressively enough to even engage the ASC to begin with so talking about it being there to "prevent me from hitting a telephone pole" is ridiculous.

If you hit a telephone pole from aggressive driving, it isn't because traction control was turned off, it's because you suck at driving. Perfect example: some 16 year old kid on here (I'm not going to mention names) crashed his X because he tried to take a 90 degree turn at like 45 mph and flew into the curb. He said that he mashed the brakes on, cut the wheel, and the car just plowed forward into the curb. Then he blamed it on the AWD system for "locking up his tires." It wasn't the AWD system, it was YOU.

You tried to take a turn faster than what physics will allow any car to do (which you would've known if you weren't a first year driver with no racing experience), you cut the wheel and mashed the brakes so hard that even ABS couldn't stop the wheels from locking, and the car plowed forward into the curb. Neither traction control or god himself could've stopped that from happening . People like him need ASC, not me, so stop with the proposterous safety comments.

 

^ I am not talking about a controlled situation, I am talking about when someone pulls out in front of you and you panic. Not questioning your ability or trying to make a stab I just want to know how it could not help in a uncontrolled panic manuever.

 

I know what you're saying, I just don't think that ASC is going to make the difference of crashing or not even in a panic situation unless you're a novice driver. Anyway, the point of all this (to get back on topic) is that it's not really that big of a deal for most people if the ASC stops working temporarily. It is my understanding that this "service needed" light only comes up under obscure scenarios anyway, like overboosting or from doing what that one guy did where he would free rev several times up to redline in his driveway until it cut on. I believe (correct me if I'm wrong on this) that it clears out once the car is cut off and cut back on again, so until mitsu releases a fix (if they even do), it's not that big of a deal. Just my .02.

 

I do autocross and I like using the ASC sometimes. It doesn't matter how good a driver you are. The function of the ASC is to add power or take away/brake in 100th of a second intervals individually to each wheel. You physically can't do this without it. If I didn't want ASC I would've saved about 10k and bought a Ralliart and spent about 4k to get it up to the hp of the Evo.

It's a big deal to me. I'm not going to forfeit 10k worth of stability controls I paid for to impress my friends at the drag strip. I'm holding off purchasing for just that reason.

Just my opinion.

 

Well put.

 

Not every knows how to drive(they think they do), adjust and compensate.

So you are contradicting what a billion dollar industry is trying to make a standard??? Ok.

Wasn't F1 that ban most of the electronics(any driver assistant computer) because Ferrari won all the races since they had the best budget and could get the nicest toys???

There's a reason the evo 10 is quicker while it is also heavier and not making that much more power, is all those computer and technical gadgets that we all like to talk down about.

 

I remove ABS from every car I own, even if the industry thinks it's better for me.
I drive only manual transmission cars, even if bilion dollar industry thinks automatics are a standard. I do not eat at McDonalds either.

 

TTP do you disconnect the ASC when you dyno tune? I remember when my STI, MR 9 and X got tuned the AWD was disconnected. So isn't the ASC service light a byproduct of the dissconnection?

 

Yes we do for a few reasons. The quarter mile passes on the dyno will invoke traction control and slow the car down. Same thing happens at the dragstrip.

For one gear pulls we want zero braking or input from the car's electronics screwing up the transmission of power to the wheels.

 

So go take your Evo X to the dragstrip and leave the awesome traction control on and we'll look for your thread in the drag racing section with your 18.3 E.T. timeslips at 94mph.

I mean after all, Road and Track and Car & Driver are all parts of a multimillion dollar media company and they test all of these cars in the quarter mile, correct?

Why are they disabling traction control? Certainly since the manufacturer put it there for the buyer to take advantage of the "$10,000" in drivetrain technology, why would anyone less than Tommi Makinnen ever not want traction control?

 

What shop was this and what type of dyno?

 

Road and Track "The Evo X is laden with technical gadgetry. Among them is AYC (Active Yaw Control), which transforms the Mitsubishi from an efficient handling sports sedan into a corner-devouring monster. AYC controls the torque split between the rear wheels, transferring power accordingly when it senses abnormalities in the car's yaw movement. In simpler terms, it drastically reduces under- and oversteer. The result is exceptional control and speed through all types of corners. When compared to an all-wheel-drive car without yaw control (like, say, the WRX STI), the AYC-equipped Evo turns in sharply and stays on the correct line as if it were tethered, even if you overcook it into a turn."

Car and Driver "But let’s not dwell on the bad, because there is plenty of good about the Lancer Evolution. For starters, it clings to the road. We recorded 0.97 g on a slippery skidpad, fighting oversteer all the while. That’s right, oversteer. Most cars lose grip at the front end during a steady-state corner, but the electronic wizardry in the Evolution’s systems makes sure the back end is the first thing to gently break loose."

The ability to turn the ASC off will always be there, but the ability to turn it on and it stay on is the concern. Don't get me wrong, the Z chip is a great product and TTP has done a great job getting the most from it. It would be that much better without any drawbacks, that's all.

 

All the fastest track times are confirmed with ASC turned off. As an experienced driver with a good bit of track experience, I can tell you that ASC is a feature for novice drivers and only slows you down. Not only that, but it's like an on or off switch that doesn't really seemlessly blend into the driving experience with minor intervention; as soon as you really get the tail hanging out it cuts power so hard it feels like you hit a wall.

If you haven't experienced this in your autox events then my suspicion is that you arent driving the car hard enough to even engage the ASC and probably aren't aware that you're not even using it. ASC doesn't ever add power, BTW, it only limits torque output and applies the brakes to individual wheels to prevent spinnage.

If you disable the first stage but not the second stage, the braking functionality still works in the rear to control the level of oversteer, but even with it being totally disabled it's still very controllable and lots of fun. Anyway, If you think that ASC is what separates the X from the ralliart, then you need to learn more about these two cars. Night and day differences in suspension and geometry, transmission, AWD system, brakes, and so much more that I don't feel like typing it out.

Seriously, if you would've bought the ralliart if it weren't for ASC and think that's where the 10k extra went, then you don't even know what you're driving right now. No offense.

Uh, wow you are confused. ASC is NOT AYC. Perhaps that's why youy are confused. AYC (active yaw control)vectors more torque to the outside rear wheel when cornering to prevent understeer. ASC (automatic stability control) prevents tire spinnage by cutting power to wheels that are spinning to prevent oversteer, effectively counteracting the benefits of AYC. The asc is really meant for extreme weather where snow and ice or severe rain are present to ensure an extra margin of safety, and for novice drivers.

EVERY MAGAZINE has commented that for maximum performance, the ASC has to be disabled because it slows the car down when it doesn't need to be. I will supply links commenting on this if you would like. Anyway, if you are concerned about this "service asc light" issue disabling AYC, which is what you are citing as being so great (and it is), it doesn't. It's just the ASC that is affected by this bug and it'll most likely get fixed by a software update soon, so I wouldn't worry about it.

 

2 different shops both with dynojet. ASC is a pita. I always have mine off. My point was that when you disconnect it you get service light. The same light seen in the video right?

 

I was more asking for the STi and the Evo 9 as the only way to "disconnect AWD" is to disconnect the drive shaft, and even then the center diff is going to spit out metal stuff on the dyno.
