it was great to read through this thread with all of the MGT, Hey, and Clacks knowledge scattered throughout.

Re: A Tuning Exercise: RUF Yellow Bird '87

[ Edited ]

I can get a handle on most cars pretty quickly. This car is another matter altogether. I have created several tunes using normal Gran Turismo logic. I normally use comfort soft tires while tuning, so as to avoid masking poor behavior behind sticky tires. The first time the Yellowbird snaps into oversteer, irritates me. The next ten times make me want to drive this beast to the nearest junk yard. Why does this car act so far out of the bounds of physics?

I have tried Clackman's tune, Master GT's tune and Priaiano's tune. While all are better than stock, none turn this car into something very drivable.

Frankly, it makes me wonder whether there are basic programming flaws in the design of this and the Shelby GT350R!

BANG

 

PS: I plan to get a handle on this if it kills me! Tonight I plan to test split tires as was common in the progogue days.

I think part of the problem with this particular car is that it may require different tuning for different tracks. The two tracks we just used had a few off-camber curves and with a light front end and the RR design, it really wasn't easy for most of us to hang on.

 

However, as I mentioned above (I think), my second tune worked extremely well on the Nordschleife, with almost no hint of control problems.

FWIW I don't get any ovearll benefit from that anytime wear is on at all.  Some balance change, sure, but then the 'bad' end gets worse quicker due to the tire split.  I don't think this RUF is broken, just a 40/60 car that isn't light nor has downforce to hold it down.  Also now I have to try the GT350R.

I can say this...the races we ran last night were more work than fun for me. Don't get me wrong, I had a blast, but it was extremely difficult to drive that thing for 10 laps around Spa and Suzuka. If you lose focus for one second, you make a minor mistake that turns into a huge mistake and you ruin what could have been a great race.

I'm guessing he's one of the drivers that didn't die while racing that car???

Yes, he is driving the car in the videos. As far as I know, he still chauffeurs passengers around the Ring.

I understand that different tracks may require a modified tune on many cars.

The thing that frustrates me most with the RUF is it's inconsistency. A Ford GT for instance can be a handful to drive with a stock tune and Comfort soft tires. Once the Ford is tuned well, it's very predictable and extremely fun to drive. The RUF on the other hand is unpredictable even with a fine tune. It will snap into terminal oversteer the second it has any significant weight distribution change. Any car be driven quick if we can understand that cars limits and those limits stay consistent. I cannot get the RUF to stay within anything but a razors edge range of acceptable handling, because of it's inconsistent behavior.

This truly is a tuning exercise!
