Thank you for 1.0 :)

First thing I checked was if windshields get wet. I checked Sauber and Porsche. Sauber - nope. Porsche - yes. But wiper doesn't work, so I don't get the logic, maybe something is wrong on my end.

I also find it a bit strange how the grip is sorted, but I am really not sure and shouldn't say anything more without more driving.

Hi Mantasisg,

As stated in the changelog the wipers are not currently working.

- Only functionality missing is fully working wiper functionality currently, but rain support is included already.

regards.

More Sauber Cars added to balance car skin ratios better, thanks Alavaro.

The Sauber skins repeat, like either the VEHs weren't updated to point to Alavaro's skins or the skins weren't included? 31, 32, 33 are fine, but then the skins just repeat 31, 32, 33 for the higher numbered vehicles.
 
A small guide about the new tyres to save testing time to everybody.

(Only for Porsche and Mazda)

- Goodyear R500 = Dunlop Sprint => (the softer compound)
- Goodyear R600 = Dunlop Enduro => (the hardest compound)
- Yokohama, this brand have an unique compound, the rear rim have a bigger diameter (19" instead 18") than the other brands. It is a medium compound with slow heating and very stable. If you treat it well it last longer than the other tires. Excellent for long runs with medium boost.

Tires were thought around warming, not only wear and grip as main target. The R500/Sprint warms more than the others by only rolling, so this compound is good for tracks with long straights with few sections of corners. The tires keeps the heat better for the next corner, i.e. Sebring, Le Mans, Road America, but they can't cold down in tracks like Sao Paulo o Portugal. The R600/Endurance is harder and resist better the long period of cornering. It warms less on the straights, so isn't so good at Le Mans or Road America where they cold down under the operational temp.

All the tires have an operational pressure around 165-170 kpa, and they take 3 to 5 laps to reach the highest pressure. So check the pressure after some test laps to set the cold pressure at the garage. The car moves to the sides until tires reach the highest pressure.

Petros and team,
Thank you for excellent mod!
Can I ask, what is the plan for mod manual - will it be updated to contain information for other cars as well?
Information on C11 there is really excellent and helps understand the car and extract more from it.

Thank's again for your time and passion on this project!

Guys, so in real life cars were H-shifted, right? Did they need clutch on upshfit/downshift?
Click to expand...

No foot clutching was needed except when in gear at a stop.
The double clutch gearbox contains two separate clutches and their own gearbox groups. One of the clutches transmits the torque to the odd-numbered gears 1-3-5 and the other to the even-numbered gears 2-4. Two gears are engaged at the same time: the current driving gear and the pre-selected higher or lower gear. The switchover is done by the simultaneous hydraulically actuated opening of the first and closing of the second clutch, therefore the twin-clutch gearbox has no shifting interruptions in normal use. When you need to change two gears at a time, let say from 5th to 3rd, then it takes time as they both are on the same shaft.

Thanks John, good, so rF2 gearbox implementation does not limit this series as much as some others. Was shifting done using H-shifter, or was it sequential floor mounted? I'd expect H-shifter, because sequential came in later AFAIK.

Also, do you happen to know if lift was necessary on shift, like in dogboxes?

Its an H-Pattern to allow multiple steps. Absolutely needs to back off the throttle on shifts in part because the turbo popoff takes a hammering and settling time when its hit with no-load full throttle at popoff threshold, at least the IMSA versions did. The whistle you hear on gearshifts on the real cars is from the popoff open-close cycle venting.

While probably not important to know for Group C of this era, sequential shifters in racecars are much older than you know. Examples: lever-shifted Lotus queerbox of the late '50s and the H-pattern GT40 Mk1/Pantera was also sequential.

AFAIK, the paddle shifting sequential gearbox is as you believe, though I don't know when the single-ring push/pull paddle shifter appeared in rally cars.
 
You are talking about the PDK gearbox. It was introduced in 1986, but it wasn't used all the time. At Le Mans they used it for qualifying but not at the race. However, I thinkg there is no way to modelate that in rf2.

Sequential shifters have been in motorcycle boxes since the time of WW1.

First car I ever drove with sequential shifting was an SCCA D-Sports Racer I built in 1980 powered by a Suzuki motorcycle engine. I was hooked on sequential by the end of my first test lap, and some 38 years later still prefer that to an H-Pattern.

Schuppan's 962 (Rothmans Porsche #2) used the PDK in the race but didn't finish. :)
 
These cars at Sebring with a DD wheel are absolutely brutal. Love it, though I am way off the pace compared to the AI.

You are right on both things. Try the AI at 85% of speed, they do 1.48 or 1.49 that is a great lap for a race. At 80% they don't get any better than 1.50

The AI speed changes brutally from track to track, but is always between 85% to 100%
