How much for the EVO 7 AYC?
I was wondering if anyone have a pricing on the brand new AYC unit (the whole thing) from the EVO 7? Use part price would help also!
Thanks
Mr. AWD

I hope you're not planning to install that onto your car.
You will have to get the whole system including the rear diff portion (w/ LSD), hydralic pump, lines, wires and the AYC ECUs...

BTW, what did you mean by the "whole system including the rear diff portion"? Are you trying to say that hydraulic part and diff part are two separate units? I was under the impression that there is only one unit in there and everything is inside. That is why I specified the whole unit originally...

mmm....as far as I can tell, the hydralic pumps are not located within the "main" portion of the AYC (rear diff). In addtion, you will need to install sensors onto your steering wheels, connecting to the AYC ECU.
For a performance car, I see a good mech LSD is the way to go (Cusco LSD), just my opinion

So far, I didn't hear about this, but if there is a pump, it would have to be driven somehow and the best place would be somewhere close to the engine.
Anyone knows more about this?

On the other hand, this whole idea sounds pretty interesting and it will bring me back with the stuff that I liked doing a while back - control systems. Either way I go, I should be able to learn a lot and have fun doing it. If it works at the end, that would be even better!
As of regular LSD being enough for the rear, I don't think that is completely true, and at the time I believe that you need to have something active in there to make a best use of the AWD system that is in there already.

Wheel speed sensors, steering position sensor, two g-sensors, AYC ECU, electrically driven hydraulic pump, hydraulic lines, hydraulic reservoir… Did I miss anything? I doubt the changes between the Evo 6 and 7 are noteworthy.
The AYC pump and reservoir is located to the RH side of the trunk. The whole mechanism uses three kinds of fluid. Gear oil for the open diff., Dextron II for the hydraulics and SP III for the AYC clutches. AYC fluid is apparently no longer available so SP III has been substituted.
Figures quoted by someone who has done the swap suggests that you are adding about forty pounds to your vehicle. With your apparent knowledge of control systems it would be interesting to see if you can make it all work in a worthwhile way.
For motor sports use I would suggest a very short service interval for the AYC fluid.

Lan Evo is right, the AYC pump is actually a separate electric unit found in the rear of the car. Check out this page, which was posted by erikgj on another thread:
http://www.lancerregister.com/faq/G04/g04.html
There is also a simple ECU schematic, so you can examine exactly what inputs the ECU expects to operate the AYC. Hope that helps

Well, people are saying that EVO 7 is much better regarding the active stuff compared to the EVO 6. Do you think that the main reason for that is addition of the ACD or AYC is improved as well?

The Evo 7 is more lively from the rear because of the ACD: when you pull the handbrake, the center diff is clutched out, not trying to catch it. AFAIK, the TME and Evo 7 AYC are the same thing.
You have to realise a lot of people driving Evos in the UK are polishers, only a fraction of them go to track days, and even less know how to drive fast. Dont take their comments for fact.
I do have my AYC for sale, and I do have people interested in it. But they do not want to buy the driveshafts and the propellor shaft that go with it, because they already have them and they only rarely fail.
The lighter the car, the better for performance, no doubt. But 40 lbs is merely the difference between two different drivers weights. Surely adding a little weight to the rear would help balancing the car better.

Are you talking about all this for your Talon? If so there is just about no way your going to make it work and have it increase performance. You are much better off getting a suspension upgrade and maybe going with the LSD's.
Here is one offered by Road Race Engineering:

See bottom of the page.
if this is for your DSM, you are trying to take a system and slap it on, and it will likely underperform, especially since your cars weight distribution and handling characteristics are probably nothing like the EVO.

Since you mentioned weight distribution, do you actually know what is it on the stock EVO 7?
As of the EVO not matching characteristics of my car, you are right. Stock EVOs are much slower and they don't handle even close to my car!
Thanks for the info!

As you said, extra weight is an extra weight. Once everything is in there, we will see whether this is going to be improvement or not!

The AYC/ACD computer also comunicates with the sports ABS system. The ABS also senses all four individual wheel speeds and supplys that info to the ACD ECU.
You would also have to make sure all the sensors on your car are compatible with the ACD ECU.
It would be a big project.
