I've just raced this Evolution VI GSR to remember it has this AYC controller.. I've raced it with 30%, 80% and 130%. Car is sooo easy to keep up with the accelerator engaged in high/slow turns, tho it might feel a bit loose at 130% but still, so much better. Best 4wd without messing around with the settings (eccept this setting :D )

Question: How does this AYC works? And what is its disadvantages / advantages? When set to full, what.. will be the negative behavior to the cars performance/handling... I know, I know what the ''advantages'' is but still... Sorry for not beeing able to put it in better words, any answers will be appreciated!
 
I drove an EVO IX for a few laps, and AYC is basically this. Technically the AYC or active yaw control works by controlling your torque. Its like a limited slip but for 4WD cars, its a differential that works on the fly, on the go, so you don't have to press many fancy buttons like in trucks to activate it. It splits your torque that your car produces to wheels that have the best control, that way it can maximize acceleration. Example, your approaching a straight the rear wheels have more grip than the front, the AYC would transfer torque to the rear wheels for more power because it grips the road the best.

With the word transfer, it pulls power away from the wheels lacking grip to the ones with grip, so front to rear transfer. Improves grip and traction. In terms of advantages, yes, the car corners like a beast! I tried to break grip in one, incredibly hard, as it just keeps on finding traction. Disadvantages, maybe a cooler name? Sounds too technical, something like Corner Killer lol is much more intense.

Increasing AYC settings means more power to the rear, and vice versa if you reduce it. If you put a lot of power to the AYC, then at times it will feel like a full blown RWD car, so thats why it might feel loose.

I don't mess with AYC settings IRL, but it might be fun to play with it in GT.
 
Evo IV, V, and VI had electronically controlled, active rear differentials, distributing power based on a set of parameters.
These included; longitudinal and lateral g-forces, steering angle, throttle position, wheel speeds etc etc.

From the VII and onwards, the center differential went from permanent to active as well.

In the Evo VIII the system was called Super Active Yaw Control, utilizing a planetary gearset which could support an even greater torque bias than the previous system.
 
Am I the only one who can't feel the effects of AYC in the game? The Evo VIs behave like normal AWD cars with most of the power going to the rear wheels. I can't feel the AYC at all.
 
AYC is what makes the rear plant, and the car oversteer slightly, when you pin the throttle in a turn. Most AWD's have a tendency to push out neutrally, or understeer, when you do this. The Mitsu's want to turn in, they want to make it. You can feel/see the pivot into the turn when you hit the throttle with AYC on.
 
I noticed a strange bug with the AYC. If you get the Fully Customizable LSD for an Evo, the Rear Initial setting will become linked to the AYC setting. Whatever you set one to, the other will end up having the same value. I don't know what PD was trying to actually do here, because in previous games you can only have the LSD or AYC, but not both. So PD was probably trying to have them somehow connected, but kind of messed it up in the process. It would kind of make sense if they were connected somehow, but it doesn't make sense that they have the same value. The LSD setting is an arbitrary number, whereas AYC is a percentage. One thing I haven't tried yet is what happens when you set AYC to something >60%, since the maximum value for the LSD is 60.

The LSD will be at 80 if the AYC is 80... Just a thing I noticed when I played with the AYC
