Dear Guy's, could it be that 67 setups are useable for 66 cars, or is there to much difference??
If so this would be helpfull getting my cars driveble!! Thanks for your advice on this,....Hez. thumbsup.gif

Hi Hez,

I don't pretend to be an expert on this, but when the '66 mod first came out I tried a few experiments with transferring setups from '67 to '66. I also took note of the information that the mod developers gave out about things that have changed between the two. These are my thoughts on the subject:

(1) Some of the cars in the two mods seem very similar, for example the Ferrari 312, Honda RA273 and others. However, as the '66 car models (visual and performance models) were developed independently from the '67 cars, there are bound to be some differences between them.

(2) And although some of the cars may look similar to the '67s, in real life there was a lot of engine and other technical development done between the two seasons, and the mod makers have probably taken this into account when designing the '66 cars.

(3) The '66 mod includes a loss of engine power at low revs to reflect real life more accurately, so first gear will have to be adjusted for most setups.

(4) The extra slipstreaming / drafting / tow that's included in the '66 mod might make it necessary to adjust the higher gears to prevent engine blow-ups and other differences on the track, especially for faster circuits.

(5) The '66 mod includes a simulation of high-speed aerodynamic "lift", which gives you less grip in high-speed corners. This may require suspension changes.

(6) The smaller '66 mod cars, with engines of 2.5L or below, will be noticeably lighter than the 3.0L '67 cars. Again, this will require adjustments to suspension stiffness. Trying to drive a small '66 car with a stiff '67 setup can sometimes feel like you're in a rodeo on the back of a grasshopper! biggrin.gifThis is especially true at circuits where you have to cut raised kerbs with your inside wheels to get a good lap time.

To sum up, I didn't really have much luck copying '67 setups to '66 cars. I don't have the space to use a FF steering wheel, I'm limited to a non-FF joystick, so I can't get the sensitivity into my setups that I would like. My efforts at tuning setups doesn't seem to pay off. After a couple of months of driving the '66 cars, I had some very basic setups that were drivable. But the big breakthrough came when the Alternate GPL Track Database started making setups available from other drivers. I immediately found that some features of setups from Dark and Steve Cloyd could help my lap times immensely.

If you have a FF wheel yourself, you might have more luck in feeling the subtle differences between setups, and therefore you might be able to tune them more easily. But me, I just find it easier to "steal" the good bits from others who have more sensitivity, more driving skill, and better lap times than I do! biggrin.gif

Thanks Saiph, you made it very very clear................., very appriciated,....Hez. thumbsup.gif

I've never tried using a 67 setup as a base for a 66 setup. What i wonder is how did the fast guys come up with the first setups, did they use 67 setups for the big cars and 65 setups for the small cars?

I'm merely a setup vulture circling above the internet, what pickings i find i mix together to see if i can find something that tastes nice wink.gif

having some experience, to develop new setup's, 67's could be a good start point...
My first similar attempt happened once I was looking for a keyboard Nurburgring setup for 65's, being unsuccessfull on finding something stable.
Having no other option, I used the Brabham 67 setup as a base: the lighter and less powerfull 67 car, the closest for 65's I have found. even being stable, not much on track and my limitation in 8:47.


Conclusion? Do it only if you can set fast setups by your own. Saiph must be right.

If memory serves (and it probably doesn't), I copied in a 65 setup, then kept playing with it until it felt right for whatever physics we were using at the time in the beta. By the time it felt right, it was entirely different. I'd then copy it to another car and change gears mostly.

Ahhhh ok, i suppose the 67 cars were far too different to be able to convert to a 66 setup easily think.gif

Thanks for the reply Steve thumbsup.gif
