Sardegna WTC 800 - help with Toyota FT-1 GT, Honda NSX GT500 08 and Bugatti VGT

[Cheesehead64]

These should be Sardegna killers but I'm struggling. The Mazda 787B is a slam dunk for me, as is the 962C.

FT-1 I can't tweak to over 774 PP - you can't adjust many settings unless I'm missing something. Also it takes a long time to get up to top speed but when you do it is really fast. I think I'm short shifting it. When should I shift?

I feel like I should be winning easily in this, the Honda, or the Bugatti but I'm not.

Usually one stop for fuel on RH, fuel map 1, should do the trick (playing normal difficulty).

Tips, set ups, strategies, etc., for any of these cars? What am I doing wrong?

I'm blindly guessing but you are probably detune with ECU and power restrictor only -- try put 200kg ballast @ -50 first, then reduce ECU, only until you reached ECU 70 but PP is still over 800 then you start reducing PP with power restrictor.

You can reduce both front/back downforce to minimum.

For transmission you probably should make your top speed about 300 km/h (~185 mph) or slightly lower.

Also check LSD settings, if you feel you're unable to turn with fuel or braking, reduce the values then. Personally I use values around 20.

What are ur laptimes with the NSX? I just won Sardegna with it. FuelMap 6, one pitstop, laptimes ~1:41. Was 1:11 ahead.

I had many different setups for the nsx and can’t remember, if I did not win a race with it. It’s a Gr.2 Car. It shouldn’t struggle.

Pre- 1.13 update the NSX was great stock on hard tires. Not sure if update put that over PP limit but it was a bit under before. First stint save some fuel and do 8 laps. Second stint full gas 7 laps. At fuel map 1 best laps 1’38 but that is overkill and will win by almost a full lap.

The NSX is even better after 1.13, as you can now fit RM tires and stay under 800pp.

The FT-1 doesn't get over 800PP as OP mentioned, so no detuning. The Honda is slightly under 800pp stock, so no need either.
Only the Bugatti needs to be detuned.

At Endurance events you should always try to detune by lowering power and not ballast (less power means less fuel consumption and also less tire wear, so as less weight). Of course there is a point where you may reduce power to a point you have too much drag to Hp and the car will struggle in terms of top speed, specially if you run long gears to improve mileage. Also, in many situations, reducing downforce will increase PP because you get less drag and more top speed.

But on that matter, the OP already detuned both the Porsche 962C and the Mazda 787B, he knows what he is doing.

@Cheesehead64 there are many things that could be happening. I used the 962C various times and some were slam dunks and some other very hard. In other hand the AI isn't always as fast or slow as you expect, only in terms of pit stops is always the same. Once I lost with the 962C, after spinning twice, because I was struggling on specially fast AI drivers and a test setup to understeery. Just to realize how much out of the box that race was, It was won by Grady in Audi R8, which usually struggles just to get on the Top 10!

Here's two Audi R18 TDI '11 detune to 799.24 and 799.27, one by ballast and one by ECU and power restrictor. Notice their huge difference in acceleration in 100-150 km/h (2.21 vs 2.81 s) and top speed (281 vs 319 km/h). I struggle with the ECU tune but easily win with ballast tune. And this tune can still finish Sardegna WTC 800 and Spa 60 min without refueling if using leaner fuel map.

The Honda is extremely quick for this race, see my setup in this post and the one above it:

These are the top 9 cars I've tested so far. Frankly, using even the Viper Gr.3 is a bit masochistic IMO, as it's just horrible to drive compared to the faster cars. NSX GT500 Gr.2 (tuned) 25:02 FL 1:36.2 F1 GTR Gr.2 25:04 FL 1:36.9 NSX Concept-GT Gr.2 25:22 FL 1:38.1 Alpine VGT Gr.1 25:31 FL...

It's almost certainly possible to make it even faster than that.

Did some rough test on Sardegna WTC 800 event, first lap. Using auto transmission to eliminate shifting timing differences.

Condition	Lap Time	Fuel Consumption
Ballast tune, fuel map 1	1'44.468	20% (4.3 laps remaining)
Ballast tune, fuel map 6	1'49.129	12% (7.8 laps remaining)
ECU/restrictor tune, fuel map 1	1'48.620	15% (6.3 laps remaining)
ECU/restrictor tune, fuel map 6	1'51.859	9% (11.4 laps remaining)

Then, using ballast tune with manual transmission, short shift at ~5000 rpm:

Ballast tune, fuel map 1, short shift at ~5000 rpm	1'45.690	15% (6.2 laps remaining)
Ballast tune, fuel map 6, short shift at ~5000 rpm	1'50.055	9% (10.9 laps remaining)

So using ballast tune you can achieve fuel economy and lap time of ECU/restrictor tune with short shifting, but still have the flexibility to run fuel rich and high RPM for sprint/overtaking.

PS. Perhaps my memory about it doesn't need refueling is incorrect, just from seeing these fuel consumption numbers. Maybe I'll retry a full race later to confirm this. By the way if I remembers correctly the Bugatti VGT (Gr.1 version) and Porsche 919 Hybrid '16 can both finish this race without refueling, and specifically the Porsche 919 will have ridiculously amount of fuel remaining even when using fuel map 1 ...

Edit: Tested. 1'44.391 with only 10% of fuel used, this is on fuel map 1 with auto transmission!

I like the R18 a lot and have won this on RH FM1 doing one pit stop. I'll have to mess around with your tunings and try to do a no stop...

EDIT: which set up is better? Faster acceleration or more top seed for Sardegna?

Cool. I'll have to try out your setups...

 

[Cheesehead64]

I ran the 787B and 962 this morning and both won by 40 seconds or so on normal mode. Laps between 1:39 and 1:44. Not sure if that's any good.

Ran the Bugatti. In the 787B and 962 I'm close to the lead around them time of the Ai's first pit (lap 5). With the Bugatti I'm still struggling to pass the cars at the tail end after several laps. Need to futz around more with the settings...

Sorry I just tested R18 TDI '11, and using fuel map 6 with short shifting I can only do almost exactly 13 laps without refueling (and I pitted after lap 12 to refuel), so my memory was incorrect ...

The one using ballast has both higher top speed and higher acceleration.

The Bugatti VGT (original version) is much heavier and has much more power than Gr.1 version, and my memory was from the Gr.1 version (duh) so it's reasonable to more struggling and need more refueling. Time to try it ...

 

[tiberiusteng]

Tried Bugatti VGT, with this tune, fuel map 6 and short shifting at 6000 rpm I'm doing 1'42~1'44 and overtaked the lead mid 4th lap, fuel tank holds for 14 laps and I pitted after lap 13 to refuel.

Noice! Gotta try that one!

The track is all about acceleration. In the other thread we discovered it's best to have min front downforce and max rear downforce, even though it makes the car understeer horribly. Both of them reduce the PP and it provides more benefit to spend the PP instead on making the car accelerate faster rather than having the higher top speed that less rear downforce would give.

 

[tiberiusteng]

Tried FT-1 VGT stock tune, fuel map 1, I shift when the red bar just appears, maybe 8500-9000 rpm, doing around 1'40~1'42. Pitted to refuel after lap 6 and lap 12, the time almost the same as Bugatti VGT but the AI's time seems way off ...

I'm sure this time the difficulty is set to normal, perhaps earlier the AI was on easy (ouch)

Just won using your set up. Fun drive. RH, 1 stop for fuel. FM 3 or 4 for a few laps but then. FM 1 the rest of the way. Won by 30 seconds...
