AYC Controller?

[MOTORTRENDmitch]

i just bought the 2005 mitsubishi Evo, and it has an AYC controller come stock... And ive never seen this before? can someone explain what it means, whats it does, and how it can help/affect the car

thanks

EDIT: I don't need any replies this is from August.. haha It was bumped pretty badly

it just gives the power to the wheels that have the most grip.
Like jeremey clarkson said
"Sometimes it can be 1 wheel drive in tight turns"

In my experience, it tends to mean the car is going to handle like a brick in tight turns. I tend to avoid the Evo for that reason or just get the few that don't have it. Surely it can be tuned to be better, but I haven't really put much time into one yet.

Real EVO's (and ones in GT5 I've tuned) have less understeer than Impreza's, so that should be your answer right there.
AYC controllers can be fantastic.

For future reference, if you click the little '?' mark on the settings page of an item in GT5 it will give you a decent explanation.

Ive not driven any Real Evo's yet so I cant compare those, but I have driven a number of Imprezzza's and the only one I would say had any understeer was "the hatch" Sti from a few years ago. In my opinion that car was a disaster to drive even compared to the Legacy GT wagon of the same year due to all the electronics and settings and knobs and switches and modes. I just couldn't get a decent launch out of that thing and it felt soooo heavy with all the body roll.

I've had good tune's on evo's in the past but haven't on gt5 yet. In tight turns like Côte D'Azur the ayc just feels so foreign to me that I lose interest in those cars. Well, all except the Super Rally Car. 👍

Also I do know what the ? box is.

You know the Nissan GT-R has computer controlled variable torque bias front-to-rear right?

Well the AYC in the Mitsi Evo is effectively the same thing but working side-to-side as well as front-to-rear.

When the car is understeering it will provide more torque to the outside/rear wheel(s) and vice versa. Change the AYC strength to change how much the torque is varied, stronger setting = greater tendancy towards oversteer (as it primarliy affects handling characteristics under power)

Automatic Yaw Control.

Where Yaw is the angle of the car relative to the desired direction of travel when viewed from above.

But does anyone have an optimal setting for the AYC or is it based on your preference?

Well if this isn't a HUGE Thread bump i don't know what is..

At least he searched.






Anyway:

I tend to prefer something around the 75 range, with a 40:60 F:R torque split. I've found that that offers the best raw grip/turning ratio for the way that I drive. Everyone is different though, so it is best for you to find what best suits you; and some cars operate differently with the same settings (for example, the post-Evo VI cars are more stable, so you can generally dial in more yaw without causing stability problems).

Indeed, asking for a tune though? wrong subforum

Oh, it's just a simple question about the AYC and it falls into the thread that's already in this section. I suppose you have no input, as you'd just answer the gent's question. Let's help the person, rather than focus on nothing important, unless the goal is to just boost your post count.

To give my input, PureHeavyMetal, the AYC setting is personal preference, but I wouldn't crank it all the way up. It also depends on your other settings. I think Toronado hinted at the other "buddy" of it, the Torque censor. You could also use the LSD settings. Cranking it up (100+) makes the oversteer run wild, especially with Comfort tires. 60-80 is okay. Lower if you can't handle the oversteer, higher if you want a fun ride.

jack it up to 100 and get a 50/50 f/r torque split and try for a Zero turn donut

 

[MOTORTRENDmitch]

AYC Controller: Active yaw control is based on a computer-controlled rear differential which can actively split torque based on input from various accelerometers in the vehicle measuring longitudinal and lateral g forces, steering, brakes and throttle position. Where ABS brakes are fitted they too are included in the input parameters. It accomplishes this via two hydraulic clutches which can limit torque on individual axles. This system should not be confused with stability control systems which utilize the braking system of a vehicle by individually braking certain wheels to rotate and slow the car (such as Electronic Brakeforce Distribution). AYC is a performance-oriented system which aims to increase cornering speeds.

You are indeed correct.

I didn't mean to bump (only joined this forum like 5 days ago) and like Toronado pointed out, at least I didn't start another thread asking a question that's already been asked. Sorry!

Thanks. I just read about the AYC on Wikipedia and heard it increases cornering speed. Since cornering at speed is something 4WD cars generally suck at, having something to make them do it better would really help.

LOL! Damned if you do, damned if you don't... You did nothing wrong, dude. Hope you got your answer.

haha don't worry about it, at least you searched unlike most.

 

[HuskyGT]

I found it to work better in previous GT titles where only the Evo could get it. In GT5 I can make the car handle much better with the torque split differential and the LSD which automatically disables the Yaw Control.

...and yes... major thread bump means that people are finally using the search option.
