Earlier today, I was flipping through an old Modified Magazine (October 2006), and I came across an item called the Motec Mitsubishi Diff Controler. It replaces the stock acd controller, and it allows us to adjust the torque split between the front and rear diffs. I haven't ever heard of this part nor anyone using it. Does anyone here have one? If so, is it a mod worth the investment?

 

So from looking at all of these posts, I guess I might be the first one testing out this item? Haha bump..

 

I'm sure it works in conjuntion with the Motec EMS, which is used very sparingly in the Evo world. Though i do know of 1 person who has posted about their Motec install on this forum, so if you simply search for the word "motec" in thread titles, i'm sure his thread will come up.

I doubt he is the person to ask about the diff. controller, but if you can find out who his tuner is, you may get some useful info...

 

Thanks I'll try that. I searched for diff contorller and other abbreviations for the product, but couldn't find anything. Well fro anyone that's interested, I have a link to Motec's catalogue with the part. Scroll down to page 20: http://motec.com.au/pdf/MoTeC_Catalog.pdf

 

^Crazy interesting. Make sure to post up findings when it comes in. I want to know how/where this installed, and what the new setting are...

 

There fixed that for you .

Anyway since the ACD doesn't actually do a torque split I am not sure how changing the software/hardware can make it do that....it may adjust the settings for how the center differential locks and unlocks ala the Ralliart custom tune.

 

Found on the Motec Product Catalogue for ease of reference:

 

So is this the torque split or the center diff lock %?

Or am I retarded and they're the same?

 

well from what it says on motec's catalogue, I'm assuming everything is percent. It seems like a nice modification to have for optimal handling when at the track. i'll look around a bit and try and find whether any companies from japan or other places may be using this.

 

if it worked as a standalone without their main ECU this would be very appealing

 

According to Motec:

This device works as a replacement for the regular ACD controller (no EMS required). They seem to imply that it will be able to adjust the torque split between the front and rear differentials, but I think it just adjusts the rate at which the ACD locks. Anyone know anything more about this?

 

I talked to the Motec Rep. at the PRI show in Orlando nad I am almost 100% posative that you will need the Motec ECU in order to use it.

 

Do you know if it splits torque? Or does it simple just change the rate at which the differential locks?

 

ive heard of more people using it in the Audi world, if you surf theirr forums ( www.vwvortex.com biggest one) im sure youll find out more how it works. Wether or not it works the same for us is beyond me.

 

The way I understand it. It has four settings where it changes the differential locks. Three of which can be selected from the existing A.C.D. controls on your dash.
I believe one can use the Traction Control Multiplexer (TCMUX) to help split torque. (Not, almost 100 % sure on that one.)
