What Is This Button For In S2 Stagea?

[Fassst]

Ok well I'm new here. only had my S2 Stagea for a bit over a week now.

Have noticed the below button and have no idea what it's for (the Jap manual is not really any help )

If someone could shed some light on this it would be much appreciated.

Thanks in advance.

torque split - 50/50 drive to the front and rear diffs

Is this generally only used for snow/sand etc.??

[Terminal]

Yeah don't use it on the road, especially at high speeds

[Fassst]

Yeah don't use it on the road, especially at high speeds

ok so this would be different to the "snow" on/off button that is also in the car then?

and thanks for quick reply

From memory the "snow" button changes the gearing (eg not using 1st) to reduce power to the wheels and less chance of wheel spin in the slippery conditions

Something like that as far as I know

Where abouts are ya?

it's ok to use, it just locks it in 50/50,great to use for quick getaway,probably wont help fuel consumption

[mitchy_]

its on the S1's too

my 260rs dont have that button!!

Buggar!!! Maybe I should unplug mine then I found a plug that fitted & plugged it in, then my 4WD light came on the other day - admittedly my diff hasn't been changed yet nor is my front driveshaft in but it may have something to do with it

This button changes your torque split for the ATTESA AWD system.

It doesn't actually "lock" anything - so its not like a fixed 50:50 split.

As you might know, the AWD system is controlled electronically (the ETS part of ATTESA ETS stands for Electronic Torque Split).

Under normal operation (4wd button OFF), the torque split is about 5% front: 95% rear or something thereabouts.

When traction loss is detected (or anticipated) on any wheel, the AWD system will direct torque away from that wheel.

Or in simple form, it will change the torque split anywhere from 5:95 to 50:50 as you are driving along, as it sees the need, in order to maintain full traction.

The difference with the 4wd button ON, is that instead of defaulting to 5:95 torque split, it will default to 50:50.

However if your front wheels start slipping for whatever reason, it will still transfer more torque towards the rear, therefore it is not strictly locked to 50:50.

I've seen this happen on a dyno - it definitely wasn't 50:50 once the revs started getting about say 2500rpm (with 4wd button ON).

It works on gforce sensors so it wont wait for the wheels to start slipping before it transfers torque to the front or rear or whatever.

It kind of "anticipates" traction loss, and in my experience it works VERY well

"apparently" there is some speed related variables thrown in to all of this as well, something about "when traveling over 80km/h the sync button function is overridden..." this may explain some of the action you have seen on the dyno.

I think theres about 12 threads on this so start digging and you will find more!

Thanks everyone for clearing this up for me.

I'm on the Sunshine Coast in QLD

page 162 stagea manual,

synchro mode, by increasing the drive force to the front wheels, the synchro mode provides enhanced acceleration from standstill and turning performance on icey roads and in severe conditions.

advice

when the synchro mode function is turned on, the following phenomenon will occur[these are no abnormalities]

.tight cornering effect when driving at slow speed.

.vibration when the engine is turned off with the steering wheel turned completely to the left or right.

switch.

off..100%of the drive force will be on the rear wheels when taking off.when the rear wheels are slipping,transfer the drive force to the front wheels.

on..the front and rear wheels will share 50%of the drive force each providing stronger takeoff stability.
