What do I leave alone on the GT-R SpecV '09?

LSD, because of the Active Yaw Control? Torque sensor, for the same reason?

Its currently at 576 HP - all removable attachments; no engine/weight upgrades.

The Nissan GTR doesn't have AYC.

To be honest, you're not really giving enough detail for any kind of worthwhile response, from even the greatest tuners here.

Start by, clearly, stating either what the problem is of what you want to overcome or trying to do / achieve.

Other infomation, like what tuning parts (custom suspension - if s stock / default or tuned - if so, waht's your setup).. What tyres you're using?? You talking about online or offline racing??

There's many different "answers" depedning on what your question is, but when what you're asking is so vague and unclear, it's impossible to find right answer, or any answer.

But, if it's an '09 GTR and you want to tune the diff, try this.

Initial:
Front = around 20/25 / Rear = around default 10

Acc Sen:
Front = around 20 / Rear = around default 12

Braking sens:
Front = around 40 / Rear = around 10

This will help make your car turn both going into and out of a corner, but depending on what tyres, brakes and suspension you have will mean that those figures quoted are about as rough of a "guestimation" you can get - not a chance of being specific until you provide more details.

That is if you're in a GTR and don't mean EVO as you quoted AYC and only Mitsubishi's have that. If you can explain what a torque sensor is aswell, that'd be cool too.

I think he means the torque sensing/torque split diff by torque sensor, you know, one where you can adjust the power bias from 50/50 to 10/90.

Sorry, I'll explain a bit further

A few weeks back, I was reading a post on these forums that talked about how the GT-R has an Active Yaw Control, and that installing an LSD on that car would ruin its driveability.

Now that I think back to it, I'm actually wrong - it was a thread about the Lancer Evo vs. the WRX STi, and people were saying Evo is better because it has AYC. I'm not sure what got me confused with the GT-R and the Evo, but i'm currently tuning a GT-R SpecV and didn't want to mess with any automatic functioning the car has.

Thanks, Highlandor, for the LSD settings. My settings were much different than that.

Yeah, agreed...

We just call it Fr/Rr power split

Less of a mouthfull!

AYC doesn't guarantee the EVO's are better, don't believe the hype, Ive been racing onine in a road car series for 10 months, the Scoobys murder the EVOs - PERIOD.

AYC is a great theory, but what some people forget is that the AYC doesn't take into account a "bad" setup in terms of suspension. So it'll be great when it's working 'with' a suspension setup, but if your suspensions setup is fundamentally causing problems, the AYC isn't a magic cure for this.

The Scoobys are fast straight "out of the box" on GT5, an EVO you could spend hours tuning an EVO and still end up seeing a Scooby just leave you for dead. Shame, I love the EVOs, but on GT5 - either Mitsubishi have p*ssed off Kaz or Subaru have bribed him because, unlike Prologue, the Scoobys kick ass on GT5.

Also, the AYC seems to have worse side affects on the X than the earlier model EVOs, this needs to be taken into account to.

With your GTR, not sure how tuning any of it will not affect any of it's in built systems, that car has quite a few.

Sometimes the standard LSD is able to deal with tuning - check out some of the RKM tunes for the older GT-Rs, they leave the LSD and torque distribution stock on some cars and they still feel great.

You might be better experimenting with 2 setups, one with a stock LSD and Fr / Rr power split, then setup 'B' having these with custom settings, see which one you prefer.

And that's the first time I think we've ever agreed on anything…

LOL

Don't worry, probably won't last long - we'll be back to our olds selves soon enough
