Hello, I am new to this forum. :57:

I am very impressed with the new EVO MR but am disappointed that the US Spec Evo MR does not get the Active Yaw Control (AYC) like the JDM version does. I currently do not own an MR yet but I would like more information about customing the AYC into the US Spec EVO.

Has anyone heard or seen anyone do this yet? I have been unsuccessful finding anyone even talking about it on the NET.

I have seen a few good Japanese videos such as “Motoring – Factory Fighters Evo 8 MR” or “Motoring – EVO vs STI” that really tested the EVO with and without the AYC. The differences are very apparent as the car with the AYC handled much better and was much faster in lap times.

I am not sure if this is just an electronic component that is missing of the US Spec model that could be added back from the JDM model or if it is the entire differential with electronic controls.

This is something I am considering waiting for in the next model if no one can do it. The AYC is just too important to leave off (US Spec always seems to suffer) as it is one of the best aspects of the car showing innovative engineering.

Ive always heard the cars without ayc are better to drive.
And from what i hear about the new evo 9 ,the gt model,similar to gsr only a 5 speed and no active yaw is already very sought after compared to the gsr with ayc

Hello,

I really do not see how they could be better to drive.What I saw in the Japanese videos would have me belive otherwise. The way the JDM Evo VIII with AYC car cornered, especially exit corning was far more controlled over the JDM EVO VIII without AYC. You could see the difference and the proffesional drivers noted it.

The same is true for the new Acura RL, it uses a sophisticated Active Yaw Control feature to help with understeer. I can't see why anyone would not want it.

I did find more information as to what comprises the AYC. It is a torque transfereing mechanism built into the Rear Differential and uses an additional ECU for precise controll. It can transfer 100% of the torque to either rear wheel during corning (cool stuff B) )

The main reason we do not AYC is because of the stupind emission crap near the gas tank on the US models does not leave enough room for the ECU/Rear Diff.

Just another reason why most factory US Spec models would have a tough time competing with JDM models of the type. :(

As a owner of a vehicle with AYC when I hear car guys/girls ask about "why doesnt my car have ayc" the first thing that comes to my mind is... they can not drive. Simply put ayc aids in car control, snow, ice, rain...only time ayc is helpful is autocross or maybe even drag.

Enjoy your car, hell learn to drive it correctly vs whine about this and that..

I see your from overseas, chances are you use your Evo for/in extreme driving thats commendable. Here in the US most Evo owners bolt on anything they can find just to drive the car to and from work and the occasional drag strip... anyone that has either been to or seen WRC or other forms of rally know that the car is not going to use its potential. This past winter I didnt see a single Evo in the snow..why..especially when the car is made for such conditions..total lack of ability

Your country is much better than us, we don't have winter / spring & autumn here. Its summer all year round. In our country we have have car park race which is too short to fully utilise your turbo. Sometimes we go to Malaysia our next door neighbour, they have one small race circuit at Pasir Gudang & one big race track F1 at Sepang. Every once a month we have traction day all cars from different make take part for a friendly match.

[right][snapback]15161[/snapback][/right]


That's exactly why i bought the GT-spec - to try to improve my driving technique without having electronics do the work. it's fine and dandy to have the AYC, don't get me wrong, but I'm trying to figure out two things:

1. how does the ACD setting affect the behaviour of the car on tarmac?

2. what is it that the GT can do that the GSR cannot?

like gevo, i'm also from singapore, and i've watched the BM video - BMI Vol 7, The Evo Strikes Back, and have seen how the S-AYC makes a difference. The Puma Evo 8 performed admirably, but the RS with the SAYC actually lost out to the Advan Evo 8 Rally car without SAYC

Without sounding offensive here, is it the driver or the car?

The acd changes the distribution of power between front and rear wheels,theirs 3 settings i think! snow,gravel,tarmac each completely different,try the snow one on normal tarmac..its fun:D

I hear that rally teams in the uk who want a evo 9 based car are all opting for the gt model rather than the "traditional" rs model so i guess its got a competitive edge over the rs.

I can drive and race just fine thank you. I am just disappointed that JDM cars of the same model often get much better factory equipment or features then the US Spec models do. This is not whining, it is FACT!

Just look at any JDM Hondas vs. US SPEC Hondas and you will see that most of the best engine and transmission technology never leaves Japan’s shores unless it has been used and is outdated there.

Personally, without the ability to drive one with AYC vs. one without AYC on a track there is no way for me to tell which is better. I have to rely on videos of experianced Japanese racers comparing the two while listening to their comments and opions, which almost always seem favor the AYC model in tests and option.

I am waiting for the Evo 9 to hit the US Shores then I will most likely buy one, regrettably, without SAYC :(
