Attesa system?

[crozo]

Hey guys sorry for he nrebie post but i'm rather new to skylines. I was just wondering how the Attesa 4WD system works for the GTR? Also is the R32 GTS4 equiped with the system? I know it controls the power of the rear and front wheels. Is there anyway to control it? like a swtich in the car or something? I was told by someone that the 4WD system for the GTS4 'switches around' the power differnential from front to rear based on road conditions. Is this true?Sorry once again for the newbie questions. Any advice is greatly appreciated.

The GTR's AWD driveline is electronically controlled. ATTESA-ETS stands for Advanced Total Traction Engineering System for All-Electronic Torque Split. This is combined with an active rear limited-slip differential. The system monitors individual wheel rotation 100 times per second and can re-direct torque away from slipping wheels. What this means in plain english is that the GTR acts like a rear-wheel drive car most of the time until the rear tyres break traction. Then the torque split is 50-50 front to rear, gradually feeding torque to the front wheels. This is why GTR's are king at launching and for ultra-fast take-off's because the initial slip at the rear tyres prevents the engine from bogging down through too much traction.

The GTS-4 does not use the same AWD system.

What is the difference between the GTR and GTS4?

do the non v-spec GTRs have lsd as well??

I thought GTS4's used the same Attesa system as the GTR? Least that's what i read. So how does the GTS4 differ then? Is it constantly on 50-50 torque split or does it shift between front and rear?

My bad! I didn't explain it properly. The GTS4 DOES have the ATTESA system, However, the calibration of individual wheel rotation is slightly different. Aside from this fact they are essentially the same. Both the GTR and GTS4 torque split is biased 100% to the rear wheels until they start to slip. When the system notices slip, the torque is re-directed and can vary to a maximum of 50-50 front-to-rear gradually feeding power to the front-wheels. To give an example of difference in each car: When gunning it out of a corner the GTS4 is much safer and more forgiving than the GTR. It won't get into such wild oversteer attitudes at such an early - and often unexpected stage. But what would you expect? One's a certifiable dangerous Group A weapon/legend and the other is a chuckable/fun sporty coupe.

Nissaner, Yes they do. Normal GTR's have an active lsd. While the V-Spec 1 & 2's have an updated electronically controlled lsd.

r we talking about R34 GTRs here?? just curious coz u said vspec 1 and 2... there r no vspec 2 for R33 GTRs??

i was wondering if my non vspec R33 GTR have lsd or not , thats all...

[SHUTO-BOY]

my mate has an active LSD on his r33 gt25t. and it was stock fitment. its very rare tho

his dash has a slip, and A-lsd lights

[Airzone]

All skylines have some form of LSD tho, don't they?

[Doctor]

i think they mean at the front wheels.

But back to the original question, does any one know about any devices that can control the torque split? I know its a pull a fuse in the r32, but what anout r33 and r34?

I saw an article in autospeed where they modified the sensors, but that sounded pretty bodgy to me. Any other way to control the torque split?

am i the only one that thinks vspec is complete shit

have drivend both aroujnd a track the v spec is great for 2 laps untill the center diff over heates and the whole car turns to shit

non vspec is better from a sporting perspective

Nissaner, I was mainly referring to R32 & R34 GTR's but in answer to your question - Yes, your non-VSpec R33 GTR should have an active lsd. :uh-huh:

[NFERNO]

so hows does the A-LSD / SLIP on the gtst r33 work then???

any benifits?

i know it makes the car heavier.......

ahh... okies... how come u know more about my car than me??

[GT-Rmgedon]

I actually worked at Nissan in Japan for a couple of years and had some input into the Skyline range.

Naah j/k. I've just read-up heaps on GTR's & had some hands on experience. Farkin Luv Em :uh-huh:

I'm currently saving for an R32 GTR to buy @ the end of the year. Still considering whether to go through with it or not coz of the daily driver aspect and just general concern. I've driven one before but don't know how that'd go on a daily basis. This is why i'm also considering a heavily modded 33GTST. But I'd rather Godzilla coz there's sumpin bout the feel of the car that just does it 4 me.

Btw, Beautiful car Nissaner, I Luv black!:burnout:
