English Racing ACD Tune Pre-Season Sale 2018
Just got word that English Racing is doing a pre-season ACD tune sale - $225 as opposed to the normal $300, until the end of March. Pretty sick deal for anyone who's been waiting to give this a shot.

i'm curious what the impact of it would be on an AYC car honestly - for the evo 8/9s with mechanical diffs, it allows more difference between the front and rear wheels, improving turn in and lock up on acceleration. what would it do for the Xs, specifically? they don't need to be any looser, so i guess make the car more understeer-y on turn-in? two active diffs for center and rear seems redundant

Well, ability to decide how much of torque/power goes to left/right rear wheel is quite a big improvement over non AYC cars and does way more than what ACD and mechanical diff could do. Whether they could be made to work even better than stock (I do strongly believe they could, btw) is probably not an easy task and reason for not having anything for those cars yet. Me thinks at least!
i.e., look at the focus RS, which has no center differential, and the rear diff which, effectively onto the pavement, does essentially what the AYC does. the rear wheels on the Focus, when engaged, are overdriven, which is like sending more power to the rear, but that is not really what an ACD does. Would it be faster with a center differential? Likely not, maybe marginal improvement.
The ACD tune on the hand for 8/9s, helps compensate for the decreased effectiveness of the rear diff by more aggressively both opening and locking the center diff

no trick, but it's pretty easy. remove the side a pillar covering, and look up and it's up there. one 10mm bolt that holds a few ground wires & the bottom of the acd bracket, once the 10mm is off, you can just pull it straight down. i believe you can send the bracket along with it

Here's my next question; what happens to the diff when the acd ecm is disconnected? Does it stay open or locked?
I put in my order so now I get to pull the ecm, but this weekend is the annual wake up from hibernation maintenance ritual. Can I drive the car to get aligned/balanced (new suspension bits) without the acd control unit installed?
