Anyone notice that in the '05 owners manual for the MR it states the "center diff dissengages at -13 degrees or lower"

It seems this can also be done by pulling the e brake

 

sti has this feature, but i didnt know the MR did, im gonan read the manual right now!!

 

Has potential for good highway gas mileage. Pull up on the hand brake just enough to get the light to engage and voila.

 

Yes, before the '03 was launched without ACD, some of us were contemplating to have this feature to use a 2WD dyno for convenience.

 

wait...when you pull the e brake just alittle it becomes 2wd??!

 

Huh? I'm confused.....Does this appy to the GSR too, or just the MR?

 

you can't say its just for the mr, its for all '05s.

 

wouldnt that hurt your e-brake?

 

It's the electronic center differential. It makes the rear diff open, i.e. mostly 2wd. You could fool the computer by tapping into the e-brake switch wire, and it would unlock the center diff.

 

Couldn't you just utilize the ACD button?

 

what?

 

it seems that doing that wouldn't be good for something... I don't know, it just seems odd to do that

 

IT is a good idea, if there is no prolong wear from it!!

 

what page in the manual??????????/

 

I read about this in 05 manual. I dont know anything about it other than that. I havent tried puling the ebrake yet. I think its crazy that if your in -13 degree weather the all wheel drive system takes a smoking break till it warms up. Seems like some owners in the northern states might actually want thier 4 wheel drive to be active in very cold weather. 300hp and front wheel drive problably aint great in the snow!

I also wonder if you could, with the e brake on, floor it, release the clutch, spin the fronts to the limiter for a few secs, and when the light goes green release the ebrake. I realize this sounds like a great way to kill the transfer case and would never do that but I was wondering if its possible.
