Hey Sarge, Check out Ricardo's GPL site, it's a great place to start: http://website.lineone.net/~richardn/ -- don New Programmes for Converted GPL Tracks http://www.ianparker1.clara.co.uk/clara.net/i/a/n/ianparker1/webspace/gpl/

Please accept my apology... Unfortunately "Jimmy" has been (albeit erroneously) part of my lexicon for over four decades and unlearning it is still very much a work in progress. However, in the interest of trans-Atlantic congeniality, I'll have another go at it. Sent via Deja.com http://www.deja.com/ Before you buy.

Thanks for the sites -- I'm readin' The differential lock-up settings never occured to me; but now that I think about I recall a discussion on this board about that just before I got GPL -- so much to learn... Thanks again, Sgt Sent via Deja.com http://www.deja.com/ Before you buy.

Okay, I've done the "one car, one track, one setup" thing with GPL off and on for a couple of months; Eagle, Spa, std setup with full-fuel -- now I've decided to attempt some setup changes (something I've had modest success with in Papy's N-series over the years), but I'm stumped. I read somewhere that Spa needs a little oversteer, but first to lower the fuel load so I can chase down the AI in those long (for me), 9-lap races -- don't laugh. So I cut the fuel load in half, with no other changes, and immediatly picked up a push (along with slightly better lap times of course) where I used to have a nice, comfortable trailing throttle oversteer... So I (very slowly), started playing with sway- bars trying to put a little more cornering load on the rear, then a pound more air in the rear tires, but I really don't want to kill rear tire stick, I want to increase the front end bite and now after lowering the front and raising the rear slightly (attempting, I thought, to play with roll-centers, hence weight transfer). What I've got now is a quirky beast that has about half the trailing- throttle oversteer I'd like (I was quite comfortable with trailing throttle balance the way it came out of the box), and a very noticeable push coming off the tighter corners which transitions into an explosive oversteer once it gets on the pipe. Braking is just plain a bear, although I seem to be able to down-shift almost anywhere in the turn without upsetting the car too badly -- I'm now officially lost... I'm no Jimmy Clark, so there are lots of driver induced problems to be sure (can't seem to tune those out either), but so far I've not touched brakes, shocks or any of the stuff I'm familar with from N1, N2, N3... This is a wonderful Sim, but at the rate I'm going, I'm going to have to start over with the BRM, or maybe a taxicab. Ideas, basic theory, websites????

The coast side settings on your differential can have a big influence on trailing throttle oversteer.

Run, do not walk to this URL: http://simracing.com/alison/gpl/ Alison Hine and her brother Nate have a program called GRE that has been of tremendous benefit to the "setup theory impared". The utility is quite useful in of itself, but the associated Help files really give you the straight poop on doing setups. One tip I can give you. The Diff settings have a lot to do with how the car will corner. Try taking a corner neither accelerating nor deceleration, but at a neutral throttle. It behaves completely different because that's the only time the diff isn't locked up. When the diff's locked (to a greater or lesser extent depending on it's settings) the back wheels want to turn at the same speed which tends to make the car understeer straight ahead.

Eh? Jim Clark was known as Jimmy as well. For example, Derek Bell, quoted in Jim Clark by Eric Dymock, "Jimmy told me, ' don't get too close when you come up to lap me because my engine is spitting and banging'...". Most often Jim, yes, but not exclusively. Tony Whitley Still so much in awe of Jim Clark that I get a lump in my throat if I crash into his computerised alter ego <[email hidden]> wrote in message news:8ib2r8$f6r$[email hidden]...
