Driven it, at auto-x

 

I digress, but not concede! Its just not worth e-debating anymore over it.

It would be really helpful if we could drive two otherwise identical Exo IXs, one with active yaw and one without, for comparison. Maybe even throw in a third car with the center diff reprogram.

I'm a magazine/DVD/internet racer about it too, though. That Best Motoring Evo Strikes Back where the rally guy doesn't have the SAYC and the other guys say the car sucks without it sticks in my head. Also that SCC mag wagon writeup where they drove the Japanese spec IX with SAYC and said our car sucks in comparison.

The only other Evo I've driven with AYC was that TME Evo VI, and it was a really early version of AYC, but I think it would whip the IX and X we had onhand on track handily, probably mostly due to the weight.

 

Before I digress, what kind of course? To me, the SAYC intervention doesn't get stark until you are up in third gear. I think on a big track, its a lot more handy than in an autox. The car just doesn't have the momentum for the SAYC to really shine on a short course.

Given the front to rear weight bias, I don't think that possible without yaw control. You can literally spin out an Evo X on throttle like a RWD car. Its highly unnatrual, but predictable since the system is repeatable, but its nothing like a mechanical diff. Drive an X in fury on a big track.

 

What would be best is 3 IX's, one with SAYC, one USDM, and one USDM with an upgraded rear diff, then run laptimes, track and auto-x. That would really put things to bed. I think the other changes between JDM and USDM IXs are minimal enough. I honestly DO think the IX handles relatively poorly without some kind of additional help from the rear though, totally agree.
The ACD thing has less to do with it, just a center diff reprogramming thing.

 

Sorry, didn't see this -

I did reach 3rd, but only in the "long" straights. A buddy of mine has one, we tried each others for a change. Rest of the course was fairly tight, staying in 2nd gear. I did notice it though, but I don't know how it's programmed to work, if there's a difference at lower speeds or not.

A post of a guy who actually spun 180 after the rear diff upgrade - the guy in the post right under said he did the same thing.

You're right though, I've not driven a X in a high speed track. Closest to that I've come is in a video game lol

 

Pics/video or it didn't happen! LOL j/k

 

Worth noting is of all the Group N Evos in WRC, none of them have AYC. Only the RS and GT (both don't have AYC) were homolgated. Probably for reliability concerns

 

lol omg i don't have any, i really don't lol. i think i have about two pics of me auto-xing from my entire career of autoxing..

lol i like your ninja edit

 

The GSR's 5speed is notchy in 2nd and third, and based on just my downshift/upshift/heel toe practicing, it's synchro related. Just don't expect the X's manual tranny to be perfect

For anyone who wants to see what non AYC feels like in an X, disable the ASC all the way (5 sec hold); it effectively does that for you. WOOOO was my reaction, the yaw rate should have been captured at the track during my upshift going around the curve, instead I went sideways and backwards. I'll leave ASC in the med setting from now on.

 

Ok I'll say it -

Disabling the ASC does not = a non AYC X. ASC is the stability control, and disabling that allows the Evo X to drive how it should, which I think was the gist of what you were saying in that paragraph..

Enjoy your Evo!

 

Disabling the ASC disables the brake control portion of AYC, it does not disable the torque control from side to side. You both were kinda right.

 

It would be easier and more accurate if you just test a VIII or IX RS then a GSR in other countries because they have the same S-AYC (although tweaked differently in an X) but not S-AWC using the brakes. VII or older models have regular AYC although it shouldn't be too big of a difference. The only 'official' tests and reports are from Mitsubishi, Best Motoring and some other Japanese magazines, they could be biased for marketing purposes. A lot of Best Motoring's drivers have kind of similar driving, somewhat twitchy and schitzophrenic, which makes it perfect friend for AYC. If you watch their driving then watch Petter Solberg or Walter Rohrl, then you will know what I mean.

Facts:
- It will add 70-80lbs
- It will increase number of mechanical parts and electrical parts
- I don't see it banned anywhere, unlike traction control or ABS, so it is highly unlikely that it improves lap time and the lap time consistancy for skilled drivers

Rumor:
- Increase in power makes it very unpredictable
- Increase in power will make reliability of AYC suffer, but I don't think there are enough cases around to prove that it is always the case

 

Are you sure you're not talking about AWC there? last I heard ayc does not involve using the brakes, though it does uses inputs from the brakes to determine its action.. pretty sure it doesn't actually control the brakes

 

There is a white paper out there that discusses everything thats S-AWC. I cannot find a link to a text version, and its too big to upload here. But on page 7, paragraph 4, it talks about the ASC button when held, will "disengage the AYC brake-control function."

 

ohh hmm interesting. makes sense that it does that when the asc is on though. but yea, asc fully off does not = a non ayc evo
