Can AYC be deactivated ?

I've pinched this photo from elsewhere, so sorry for the red arrow and the light reflecting off th interesting bit! Anyway......

Over near the right hand side is a list of fuses. The one that you want to see is fuse 17 I think. The picture on the top of the fusebox (in the engine bay by the battery) shows what I think is two wheels joined to a diff by half shafts. There are arrows pointing in different directions, which I believe to be the symbol for the AYC.

IIRC it is an opaque yellow colour when you lift the cover.

Hope that helps!

is there an AYC Controller??? or somethin like the GTR'S have to distribute the front and rear diff ratio makin it more rear wheel drive than front sort of thing???? and if so where can i get one from? email reply to masta_bazza@hotmail.com please as im travelling
cheers

The aYC is in the diff (not the transfer box), it controls the power split between inside and outside wheels, see below

AYC
Active Yaw Control
The AYC system controls the vehicle’s rotational forces (roll and pitch movement) by sensing road surface conditions, steering wheel angle, lateral acceleration and electronically controlling the distribution of power to the left and right rear tyres. When entering a curve the power is applied to the outer wheels thereby improving manoeuvrability. When accelerating in the latter half of the curve the power is transferred back to the outer wheels to reduce understeer.

Check out mitsubishi motors .co.nz for all the technical info.

Try this link to see why it is quite a good thing!

These cars are very clever, there are sensors everywhere, if you have ASC it is a combination of AYC, TC, ABS,if you are on full lock and you accelerate, the car will react differently, also throtle sensor knows how hard you press the pedal, the auto box learns how you drive, toooooooo much stuff to go into, read up about the set up and research and development.
This car brakes without you touching the brake pedal, there was a problem with this and this was part of the ASC recall, anyhoo you are sitting on a lot of technology, don't just rip it all out to save weight!

try the link again!, check AYC video on this page, and read the rest!

OK so AYC vs LSD....
I have a manual with LSD (that makes it a type V?), I'm wondering am I able to install the AYC system and if so I might as well chuck in the Evo 8 diff and S-AYC right? The other side of teh argument is keep the LSD but upgrade to a Cusco item, would this be an Evo one?
fatmikenz, how did you go building the car for superlap? I'm thinking along the same lines too

[bradc]

It would be near impossible. You would need to install the G-sensors, the ecu, AYC pump and diff as well as all of the lines.

Easier just to get a really good cusco one Most EVO diff's should work.

If you get rid of your LSD for AYC I would be interested in buying the diff off you (or swapping for standard AYC if you prefer) as I will probably want it if I RWD the galant

tyre pressure is the first thing to check, then check that your tyres are worn evenly.

Agreed, I have had the same issue in the past and once my pressures were corrected the problem went away. Credit to AYC system though as it is very sensitive.

[timiano]

Without AYC =



Further compounded by shagged rear brakes, and bald Toyo Proxies!!

[bradc]

ahh yeah, but without AYC you have a completely open rear diff, which is quite different to an LSD.

Nice pic though! Do you have a bigger version?

[Nick Mann]

Heh - it's a nice pic if you know he is facing the wrong way!!

Castle Combe, earlier this year, I believe.

Like some other people I assumed all the late model VR4s had AYC. Anyone been lucky enough to drive both the AYC and LSD type VR4s? It might be the way I drive but I feel the VR4 understeers a bit, either of these options are going to influence this characteristic? Unless theres another way such as getting more power to the rear wheels....

Well if I win lotto this week I'll buy another car and do both just to find out!

[Subaru ETA]

i feel my car tends to oversteer more....

[bradc]

Uc has an LSD equipped type V Galant (similar to your car really) but I haven't driven that one enough to know how it handles, and I don't think he has driven an AYC car enough to know either!

[Subaru ETA]

i have driven uc's one at speed on windy roads and to tell you the truth...i didnt even realise it didnt have ayc!

Ive just taken my legnum out for its first run in the wet today and went a little to fast round a corner on a back street to see AYC in action but my car started to slide and none of the AYC lights came up on the dash. Does this mean its been disabled by someone. I had a look at fuse box by the battery and that all seems fine.

Probably. It is really easy to get one or two bars to light up in the wet. If it was sliding then you definitely should have had 2 or 3 bars

[bbunnys]

So if its not the fuse im guessing it would be costly to get fixed

If it is the fuse, it has probably been pulled intentionally to hide or as a cheap fix for a problem.

May or may not be costly to fix.
