I mean, sure it may be useful if you plan to take the Evo in the snow or mud, but how many of you plan to do that?
Besides, if THAT is the plan of action, Mitsu should've anticipated that these people are hardcore. But hardcore people can choose the RS instead. And guess what: the 3-setting switch on the RS is an option. Which leads me to believe, even in competition trim, it's not necessary. Hence a gimmick
Again, all IMHO.
Oh people might point out that since AYC isn't available in RS, that it's a gimmick too if following my logic.
No, AYC DOES work. It works wonderfully I must say.
ACD switch does work as well. But it works to promote more understeer. So MAYBE it's good for the newbies pushing this car for the first time around the track. Other than that... well like I said, maybe it works under snow and gravel conditions but I don't know anyone who has tried it.
By the way erikgj, the ACD details you provide, that sounds like AYC. You sure that's what ACD does, in STANDARD form?
Oh wait put it this way: ACD by itself, that is the center differential, DOES work I have no doubt about it. But the 3 switches are options which I think hardly anyone will EVER use for real.
So an Evo with ACD and AYC 100% in Tarmac mode is good enough for me.

First, I don't know about your friends but almost everybody I know who has a 7 uses the ACD settings. In addition, most of them say that the "Gravel" setting gives the best balance on dry tarmac. I also switch to the "snow" setting when it is wet.
You clearly don't understand how the ACD works - erikgj simplified it. The actual inputs are - steering angle, throttle position, speed of each wheel, longitudinal and lateral g force, vehicle speed plus another I cannot remember. The ECU basically works out the ideal front/rear torque split and constantly adjusts it. The three settings are just different programmes. I personlly think their names are misleading. In fact, the fastest track times achieved in Japan during testing were achieved on the gravel setting. Driving style will determine which setting best suits you in any given condition.
Next you say the AYC works wonderfully. Well, it is a lot better than on the 6 but you can still feel it having an effect and it is far from perfect. However, it is close enough to being good that IMO, its not worth changing. Interestingly, when using the K1 ACD ECU, the AYC seems to behave much better. I suspect this is due to better power distribution to the AYC.
As for you being happy with the ACD always in tarmac and the AYC, great. But not me or many others I know.

About the RS and options on that one, you are off too. That car is meant for people that are planning to race the car. Why would they spend some extra money to have a factory brakes or differentials or anything else, when they will use their own anyway, which is more appropriate for the hard core racing. RS has 3-setting switch an option just for that, but not because the car doesn't need it as you might think of it.

Instead of thinking that Tarmac is the standard mode for the ACD, you should think of it as the most aggressive settings, which creates most of the oversteer in the car. The Snow settings one the other hand is more like the normal (kind of like 50-50) distribution between the front and the rear. If you would have no active diffs in there, that is most likely how would the car feel.

As of the reason, how is just a marketing thing between the BOZZ and the Cusco...

I have a ? MrAWD
Does the ACD vary the percentage of front to rear power beyond the setting it is programed for (ie. even though TARMAC mode is 60/40 rear to front it will vary the percentage based on inputs)?
