Review
I thougt I give this tune a try since I'm participating in the Nissan Silvia Championship here on GTP.
So I setup JG's tune, but realized that i must be missing some parts because the car ended up with 559PP - 422 BHP @7400 RPM, 43 kgfm @7000 RPM. Maby I'm missing the engine tune.
Anyway, I tested it against my own tune @ 535PP on suzuka on RS tires.
Pros
The Car feels really stable and it is, no surprises at all. There's no tail wagging at all, unless you really provoke it. Even at the hairpin and the chikane you can put your foot down and the car just puts the power down to the black stuff.
Troughout the corners there is no change in how the car handles, it feels like you have tonns of grip, and again no surprises at all.
You feel really confidece in the car once you have done a couple of laps in it.
+Stable
+No surprises
+No change in the handling
+Confidence in the car/setup
Cons
The feel you have of neverending grip with this tune, comes at a price. And you have to pay with understeer and loss of valuble time.
Allthough it delivers the power to the ground, you can't put your foot down early because this, more than likely will result in understeer on the exits.
This means you loose time.
The turn in suffers a bit of the same, its not sharp so go a little bit too fast into a corner and you miss the apex. And its difficult to adjust the speed and racingline at this moment because lifting off produces understeer and so does breaking.
Also I feel that the tune hides/removes the true caracter and qualites of the car.
Conclusion
I think JG sums it up in his own comment on this tune:
"Certainly a tune subject to revision, I just wanted to get another tune up before I leave on holiday for the the next few days".
This tune needs more work. The Silvia is a bit of a happy dog in its original state, it likes to wag its tail. Instead of removing this trait it should be used to your advantage. The understeer is not huge or dramatic in any way, but its there.
The tune isnt bad, but needs to be refined.
