Definition / Meaning / Explanation of AYC
we should all know by now the usdm evo 9 isnt getting the AYC
, but maybe / hopefully the usdm evo 10 will get this equipment

Q: What is Active Yaw Control (AYC)?
A: From the Evo 4 onwards (GSR models) Active Yaw Control was introduced. It is a type of active rear differential that helps to provide maximum traction to individual rear wheels according to sensed forces on the car and the drivers input.
Q: What are the benefits?
A: Due to the nature of the design of normal ‘open’ type differentials they will transfer torque to the wheel offering least resistance. You can see the effect when one wheel of an axle fitted with an ‘open’ diff is in mud and the other wheel is on tarmac. The wheel in the mud (low grip, least reistance) will just spin away while the one on the tarmac (high grip, high resistance) does nothing! You can also often see this process happening on the track, especially on the front axle of normal road going FWD cars. When entering a corner the outside wheel becomes heavily loaded due to weight transfer while the wheel on the inside of the corner becomes unloaded. With an ‘open’ diff the inside wheel can spin as torque is transferred to the wheel offering the least resistance, which is the inside wheel. To stop this torque loss a Limited Slip Differential is often fitted, especially to high performance cars. Limited Slip Differentials (LSD) come in various designs but their one aim is to limit the torque loss (‘limit’ the ‘slip’ of the wheels) and to transfer it to the wheel with the most grip and therefore providing better traction. Standard LSD’s are totally mechanical in design and can only provide torque transfer in one direction proportional to the amount the ‘unloaded’ wheel is spinning. Mitsubishi’s Active Yaw Control system builds on this principle and adds electronic control of the torque transfer.
AYC has several advantages:
* It can help equalise the loading of all four tyres and therefore provide the maximum cornering potential.
* Understeer when cornering is reduced as a Yaw moment can be set-up by torque transfer at the rear wheels.
* Sharp corners can be taken with smaller steering angles than normal due to a Yaw moment set-up by torque transfer at the rear wheels.
* When driving or pulling away with the left and right wheels on surfaces with different friction levels the AYC can transfer torque to the wheel with the most grip.

no need to remind us of what "were not getting"you still getting 0-60 times/ 0-100 times at a track that doesnt give out this info on their timeslips?

Oh and you got nothing better to do but to start dum a$$ threads. From now on anytime you post one of these non essential threads, I'm going to bomb you out for the mere fact that everytime there is a good iformative thread about guys getting harassed by the police and looking for answers to help, all you can do on everyone of those posts is type "stupid pig"
So no, I won't keep the negitive posts out of your thread, by any means do a search where there is something about cops and you will see all you can post is " stupid pigs or stupid pi@s"
Also get a life I have been on here several times and have heard many people say that all you are is a post **** trying to get that post count up. Your a classic for starting a dumb thread, then having some dumb first post, then finally you post up information from a magizine that everyone has read!!!
You are on the ball bro!!! Keep it up

But anyway, I'll stay out of the mans threads, I have to admit one of the reasons I did it is because of the great responses he has put in the police and cop threads.
No foul, it's all good.

So your kind of right in a way, thanks for reminding me.

go pull over someone to make you feel better...
this thread is important to the people who want to know what ayc is. and if and when they try a search, they will find it.
and if its not important to you, then dont post. keep your stupid comments to yourself, and if i wanted to be a post ***** i know i would have quite a bit more posts than i do now
btw - go back to driving your car and stay off here.... at least my threads. can you get that through your thick skull; you 'think you are above everyone else' cop?

Evo-Police...it looked like a perfectly informative thread until you came in here and acted like a jackass. If anyone's the idiot, its certainly you. If you have a problem with him making Pig comments on the forum, then maybe send him a message instead of jacking his thread.
