Evo 9 Ayc Wiring Setup?.....?
Ok.. after watching best motoring (http://www.bestmotoringvideo.com/) i have to get an evo 9... untill i heard about all the S**T the usdm model doesnt have.. like ayc better turbo engine etc.. i can live without the engine and turbo but no AYC(Active Yaw Control) come on.... so my question, has anyone tried to wire up a jdm AYC controller and all the nessecary item such as ecu, suspension im guessing. to get AYC running

Plz help me out i really want an evo and if i cant have the features that make it an evo then all it is a sti


Ps. im not buying an EVO X

also what is the diffrences in the jdm evo 9 mr vs usdm evo 9

 

A proper suspension on an Evo CAN handle as well as an Evo equipped with AYC -words taken from the horse's mouth, Robi.

As far as answering your question, I don't think anybody has put forth the effort in converting one, at least not on this forum.

 

It doesnt have ayc....nobody has put it in. Please tell us why ayc is so important, to me its another piece that can go bad and break and cost me a lot of money.

If the ayc makes the evo and evo then your just plain ignorant to what the car is.

if you want jdm go to japan......your only option is the usdm which is an evo in every shape and form as the "jdm" evo - if you dont believe it then do us all a favor and go buy an sti

I see you came from the jdm crush honda world - if it ain't jdm it aint worth having attitude.

 

they unfortunately left out ayc, they have acd. if you are not familiar with this feature then do a forum search about it. A C D Active center differential.

 

Who cares, you won't notice the difference which, in the vast majority of situations, would be minor anyway.

 

Emissions equipment take up the space where the AYC is supposed to be. Plus, for the price of a AYC, you can upgrade your suspension with change to spare and have a car that corners just as well if not better.

 

I thought the purpose of the AYC is to "improve" the driver, not the suspension. If you're not a professional race car driver the AYC can allow you to drive faster (or maybe safer)?

 

ALOT of the Evos that Best Motoring have used for the "battles" (track) have been the JDM RS which are non AYC.
Ive seen nearly all the Best Motoring videos from Evo 3 onwards and there has always been very very little difference in the track times. Often the RS are quicker than the GSRs because of the weight difference.

Here in New Zealand we have a massive amount of Evos from E1-9 (and have had the x since the beginning of Nov 08).
Alot of people change out the AYC in their cars because of longevity issues and the fact that the LSD is nye on perfect anyway. ACD has made more of an impact with the handling than the AYC.

It must be noted that all the AYC diff housings are alloy and are much much weaker than than the mech diff. The worst car to have for part time track/drag events would be a JDM Evo 9 with 6-speed gearbox, AYC and the self exploding turbine wheel that came on some models.

Save yourself some money, get some good suspension and some lessons if you are going to track your Evo.

THE GRASS IS NOT ALWAYS GREENER



Oh yeah- here are the approx prices(dealers retail) for very good condition stockish used JDM and NZ new Evo that you can buy here

The US dollar is 45% weaker against our dollar at the moment compared to the historical average, so makes the US$ higher.

Evo 1-3 are so cheap now that there are none which havent been molested and rack up ALOT of miles (just like Gen 1-2 DSMs)

Evo 4 US$8500 JDM GSR/RS 60000 miles
Evo 5 US$10000 JDM GSR/RS 45000 miles
Evo 6 US$18000 JDM 35000 miles
Evo 6.5 US$25000 JDM 30000 miles
Evo 7 US$18000 JDM GSR/RS 30000 miles
Evo 8 US$20000 NZ new JDM spec GSR with AYC/ 5spd dox 20000 miles
Evo 9 US$28000 NZ new JDM spec GSR with AYC/ 6-speed box 20000 miles
Evo x US$43000 NZ new JDM spec with all extras including brake/aero package etc etc Brand New

 

^ Also, I heard that the AYC on previous models requires extra maintenance more frequently compared to the mechanical LSD.

 

yu odnt need it

 

Yep, it requires a top up of fluids and if needed a full bleed, not as easy to work on as the RS diff.

Aaron, where have you been, we've been wondering what you've been up to.

 

Mech Lsd maintenance is very very simple if you use the correct fluid
I run an Evo9 LSD in my Airtrek Turbo.

The maintenance on the AYC units is complicated and requires special tools.
The actual AYC diff unit itself has remained pretty much the same from evo 4+ only the AYC control ecu has improved over the years.

 

good post monsta

 

To be nice & answer your question...
Other than the already-stated; no AYC
- JDM rear bumper is different...easy to purchase & install (i has it)
- JDM head & tail lights have the amber piece on the BOTTOM...MRs have flat black housings
- JDM seats; side moldings hold you better...USDM versions are tailored for fat Americans

That's all I can think of off the top of my head...do a quick search and you'll see tons of threads already out there.

 

I would think that unless you are on a pretty slick surface, the rear LSD will do pretty much the same thing as the AYC if you're taking a corner hard.

The marketing info on the AYC states that it supplies more torque to the outside rear wheel in corners to provide more rotation.

If you're on tarmac and taking a corner hard without the AYC but with the LSD, the inside rear wheel will be unweighed as compared to the outside rear wheel. With enough torque delivered to the rear wheels, the inside wheel will start sliding, and the LSD will supply more torque to the outside rear wheel. Same as the AYC, though maybe the AYC will transfer torque before the inside wheel starts sliding.

If you're not taking that corner very hard, the LSD will allow the outer wheel to turn a bit faster because it's taking a longer route through the corner. But because it's not a fully open diff, a little bit more torque than necessary will be delivered to the inside wheel, just because LSDs are not perfect and always resist any slippage to some extent (even below the breakaway threshold). But this should be very minor, and if you're not on the edge of breaking away, it shouldn't matter anyway.

So the minor benefits of the AYC vs. the LCD are probably outweighed by the LCD's reliability benefits mentioned by others.

I'll concede that I'm a bit of an Evo newb, so if I'm off base here, I'll gladly be enlightened.
