Setup Matrix (for virtual racing) |
||||
This document is intended as a quick reference guide. It is not supposed to include detailed explanations. Please refer to the source material, if you want more detailed explanations of what's going on. Virtual racing is a fantastic hobby, and is certainly not for everyone. However, if you have the patience to persevere, it can be very satisfying. I set this up to help solve specific tuning problems. That is, sometimes I get in a car I don't know, or on a track with some extreme(ish)/odd situations/corners (Knutstorp), and I want a quick reference to see which adjustments I should be fiddling with. This was originally a paraphrase of the setup guide in the back of the handbook from EA's F1 2002, but I have added sections from a few online sources, and given credit when I did. For actual explanations of various bits, I highly recommend you read RacerAlex' Avanced F1 Setup Guide (http://watcher.drivingitalia.net/index.php?name=Downloads&d_op=viewdownloaddetails&lid=23) NOTE: This was based on information from a variety of sources, and is supposed to be a general purpose tool, so not all items apply to all cars. Link to the PDF version for download, and printing. Link to a quick reference card, based on this guide, by Jake Francis I certainly take responsibility for my work.

Engine Brake Mapping will affect how much the engine helps slow down the car - lower numbers result in MORE engine braking, which also uses less fuel. The downside is that the engine only slows down the driven wheels, which can cause a braking imbalance between high and low speed. From the rFactor ReadMe |

Preload affects how quickly the transition between power and coast differential occurs. If you used a preload of '1' and slammed the throttle down you would get a very quick transition to whatever your power percentage age was, the reverse would happen with taking the throttle off. With a higher preload the above effect would be a lot more gradual. TKD in the RSC rFactor forum (http://forum.rscnet.org/showpost.php?p=2626021&postcount=24) People tend to use the words "understeer" and "oversteer" when describing the effect of the differential lock. In reality, oversteer is truly the only thing you are actually adjusting. It's only because a lack of oversteer naturally moves the car closer to an understeer condition that understeer is used as a descriptor at all.

10.a | It's become apparent that a couple of the works on virtual racing are incorrect on this point. Notably the EA Sports F1 2002 manual. Think of it this way: A weight can only ever have 1G of effect in a downwards direction. As you go faster round a corner the weight has a greater lateral effect. If you are going round a 4G corner, the weight is acting laterally with four times the effect of its weight acting downward. Front engined cars understeer, and rear engined cars oversteer - ask a Porsche driver. |

Slow damping affects the weight transfer of the car's sprung mass (chassis pitch and roll) on the springs; fast damping controls the springs response to the deflection of the car's unsprung weight (the tire/wheel/hub assembly reaction to bumps) RacerAlex' Avanced F1 Setup Guide (http://watcher.drivingitalia.net/index.php?name=Downloads&d_op=viewdownloaddetails&lid=23) |

Simulating understeer, and oversteer during cornering with the brake, and/or throttle |
|||
21.1 |
Increase Brake |
Decrease Understeer |
This applies to a car that is neutral, or understeering slightly going into a corner, and has a forward brake balance. As you apply brake pressure, the weight balance moves forward, the front wheels gain a little more traction, and the nose points in more. Too much understeer cannot be corrected in this manner. |
|
21.2 | Decrease Throttle |
Increase Oversteer |
If you lift sufficiently during cornering, the rear tyres will break traction, and the rear end will come round. If you do this carefully, you can use this tool to point into the corner. For this to happen, you do need to be carrying enough speed, and you do need to lift a little quickly. |
|
21.3 | Increase Throttle |
Increase Oversteer |
As long as there's enough torque available at the time, you can make a car's back end step out during cornering. You can take advantage of this by lowering the gearing, so you're in the meat of the power band during the corner in which you'd like to induce oversteer. |
|
21.a | These are the essential components of 'trailbraking' and using them as such requires a good touch, and sufficiently sensitive hardware, in a simulator, to feel, and control the effects as they happen. You also have to get the other components balanced so the car doesn't 'snap' around on you, and you have to have enough cockpit time to know what you're feeling, and predict what will happen. |
|||
22 | ||||
22.1 | Increase Axis Travel/Decrease Sensitivity |
None |
Reduce apparent nervousness; Allow a finer degree of control. |
|
22.a |
This is, of course, a matter of personal taste. However, after consulting with a number of hard-core gamers, you are looking for as much control, and as much feeling as you can get. When talking about first person shooters, the general advice was to set the mouse sensitivity as low as you can stand. This takes some getting used to, but pays dividends in accuracy, or so I'm told. As this applies to driving simulators, you want as much steering wheel travel as you can stand (It will take getting used to.), and as much pedal travel also. This may seem counter-intuitive, but think about it: You don't want minor twitches to have large effects, and you want to be able to make the finest possible adjustments during maneouvering. With force feedback equipment, this lets you set more, and stronger forces, thus allowing you to feel more of the road without having the wheel ripped from your hands. Note that some drivers turn off the software that comes with the equipment, preferring instead to use the in-game controls alone to set the force feedback, button mapping, and so on. This is also a matter of choice, and possibly system resources, but you may lose some features by turning off the manufacturer's control software. Note also that some controller software has one effect, and the in-game adjustments are overlaid on the system settings, so turning off the controller software requires retuning the in-game settings. |

CaveatInclusion of a link in this list is by no means an endorsement. However, I am certainly not an authority on racing chassis tuning, and some of these guys might be. Also, some of these links are quite simulator-specific, so get what you can out of them. I do, on the other hand, wholeheartedly support anyone who would take the time to write something to help the community, and post it for all to read ;-) My personal preference is to drive a car that feels like a real car, and have a setup that might be usable in the real world. Suffice it to say that alien setups are, for the most part, unrealistic. They'd either rip the tyres to shreds, break components, or actually injure the driver. The common response is "We don't drive those cars; we drive these cars." so you decide. |
