BMW M3 transmission setting - pwp71 - 11-24-2006 What do you think about these setting (M3 car): [ transmission ] gears = 5 gear-ratio-r = -3.51 gear-ratio-1 = 2.77 gear-ratio-2 = 1.95 gear-ratio-3 = 1.50 gear-ratio-4 = 1.21 gear-ratio-5 = 0.95 shift-delay = 0.07 [ differential ] final-drive = 3.98 anti-slip = 600.0 pwp71 - thelusiv - 11-24-2006 How did you come up with these values? Are they from a real E30 style M3 like the one in the game? - pwp71 - 11-24-2006 No, it's not real values. I catch them from sports car gt except gear-ratio-5. Do you want only original values? - thelusiv - 11-24-2006 We try to stick to cars original values as much as possible to keep things feeling realistic. The exception is cars that aren't real, for instance the AX2 is not a real car at all, so we have a little liberty to set up the car as we want to. However most people who come to the game will expect the cars to drive like their counterparts in real life. As soon as the opportunity presents itself I have a lot of work to do getting our car parts system working again. When that time comes we will need some different parts and this would be a good place to put alternate transmissions, tires, etc. for people to swap out with the regular model. - pwp71 - 11-24-2006 I've found this link: http://www.s14.net/specplus/comparisons.html I'll try to use some of these setting. Which car is precisely? M3 E30 ...? - thelusiv - 11-24-2006 Yep, ours is the E30. The site you linked to has several nice upgrade options. - pwp71 - 11-24-2006 I've made 2 versions of M3 E30 2302cc with 195bhp ---start of 195bhp---------------------------- [ engine ] position = 1.42, 0.0, -0.24 mass = 180.0 max-power = 1.46e5 peak-engine-rpm = 6750.0 rpm-limit = 7000.0 inertia = 0.25 idle = 0.02 start-rpm = 1000 stall-rpm = 400 fuel-consumption = 1e-9 torque-friction = 0.0003 torque-curve-00 = 1000, 130,0 torque-curve-01 = 2000, 137,0 torque-curve-02 = 2250, 148,0 torque-curve-03 = 2500, 149,0 torque-curve-04 = 2750, 146,0 torque-curve-05 = 3000, 152,0 torque-curve-06 = 3250, 156,0 torque-curve-07 = 3500, 161,0 torque-curve-08 = 3750, 165,0 torque-curve-09 = 4000, 170,0 torque-curve-10 = 4250, 169,0 torque-curve-11 = 4500, 166,0 torque-curve-12 = 4750, 174,0 torque-curve-13 = 5000, 183,0 torque-curve-14 = 5250, 173,0 torque-curve-15 = 5500, 172,0 torque-curve-16 = 5750, 169,0 torque-curve-17 = 6000, 167,0 torque-curve-18 = 6250, 164,0 torque-curve-19 = 6500, 152,0 torque-curve-20 = 6750, 146,0 torque-curve-21 = 7000, 145,0 [ clutch ] sliding = 0.27 radius = 0.15 area = 0.75 max-pressure = 15400.0 [ transmission ] gears = 5 gear-ratio-r = -4.23 gear-ratio-1 = 3.72 gear-ratio-2 = 2.40 gear-ratio-3 = 1.77 gear-ratio-4 = 1.26 gear-ratio-5 = 1.00 shift-delay = 0.07 [ differential ] final-drive = 3.25 anti-slip = 600.0 ---end of 195bhp----------------------------- 2302cc with 220bhp ---start of 220bhp---------------------------- [ engine ] position = 1.42, 0.0, -0.24 mass = 180.0 max-power = 1.65e5 peak-engine-rpm = 6750.0 rpm-limit = 7000.0 inertia = 0.20 idle = 0.02 start-rpm = 1000 stall-rpm = 400 fuel-consumption = 1e-9 torque-friction = 0.0003 torque-curve-00 = 1000, 150,0 torque-curve-01 = 2000, 160,0 torque-curve-02 = 2500, 176,0 torque-curve-03 = 3000, 163,0 torque-curve-04 = 3500, 181,0 torque-curve-05 = 4000, 189,0 torque-curve-06 = 4500, 183,0 torque-curve-07 = 5000, 197,0 torque-curve-08 = 5500, 187,0 torque-curve-09 = 6000, 193,0 torque-curve-10 = 6250, 184,0 torque-curve-11 = 6500, 163,0 torque-curve-12 = 6750, 158,0 torque-curve-13 = 7000, 155,0 [ clutch ] sliding = 0.27 radius = 0.15 area = 0.75 max-pressure = 15400.0 [ transmission ] gears = 5 gear-ratio-r = -4.23 gear-ratio-1 = 3.72 gear-ratio-2 = 2.40 gear-ratio-3 = 1.77 gear-ratio-4 = 1.26 gear-ratio-5 = 1.00 shift-delay = 0.07 [ differential ] final-drive = 3.25 anti-slip = 600.0 ---end of 220bhp----------------------------- About the torque I catch the information at this link: http://www.bimmers.com/clubracing/archives/e30m3-chips.html (I use stock and Sprocket) Certainly there are something to adjust. In my opinion between the car is too slow (for my test I used Monza). Someone could give me some advice. About total weight, is the sum of the total mass in file M3.car? Thanks. pwp71. - osiris - 11-25-2006 Your values are in ft-lbs I think torque's unity is N m in this game. Multiply everything by 1.35581807 But the M3 is good and it's great that cars are being improved. - pwp71 - 11-25-2006 Thank you very much osiris. Now seem to be a little better. I agree with you, M3 is one of my favorite car when I play SCGT.

Thanks pwp71. - osiris - 11-25-2006 I've checked about mass and it's very close to values in your links. (mass of the car according to your link - mass of the car of the mage including the driver =200 + 200 + 230 + 230 + 50 + 25 + (0.05 * 17) + (19 * 2) + 90 + 180 - 1 235.8562 = 7.9938) This car is quite good as we can be fast in corners⦠- thelusiv - 11-26-2006 Thanks for your research on this, I'll adjust the M3 files and check it in once I get a chance to test it once, unless someone else beats me to it. - osiris - 11-26-2006 With the Landshark, in N-m, with the mass modified to fit the total mass more acurately with your values : [ engine ] position = 1.42, 0.0, -0.24 mass = 172.0 max-power = 1.65e5 peak-engine-rpm = 6750.0 rpm-limit = 7750.0 inertia = 0.20 idle = 0.02 start-rpm = 1000 stall-rpm = 400 fuel-consumption = 1e-9 torque-friction = 0.0003 torque-curve-00 = 2000, 217 torque-curve-01 = 2250, 232 torque-curve-02 = 2500, 233 torque-curve-03 = 2750, 236 torque-curve-04 = 3000, 236 torque-curve-05 = 3250, 240 torque-curve-06 = 3500, 249 torque-curve-07 = 3750, 259 torque-curve-08 = 4000, 270 torque-curve-09 = 4250, 270 torque-curve-10 = 4500, 270 torque-curve-11 = 4750, 278 torque-curve-12 = 5000, 282 torque-curve-13 = 5250, 275 torque-curve-14 = 5500, 274 torque-curve-15 = 5750, 267 torque-curve-16 = 6000, 256 torque-curve-17 = 6250, 245 torque-curve-18 = 6500, 236 torque-curve-19 = 6750, 228 torque-curve-20 = 7000, 218 torque-curve-21 = 7250, 216 torque-curve-22 = 7500, 182 torque-curve-23 = 7750, 156 - pwp71 - 11-26-2006 Another modify: All four wheel: 205/55VR15 tires on 7x15-inch cross-spoke alloy wheels [ tire-front ] radius = 0.3032 [ tire-rear ] radius = 0.3032 All E30 M3s have vented front disc brakes measuring 11.1-inches (280mm) and solid rear discs measuring 11.1-inches (282mm). ABS is standard. [ brakes-front ] radius = 0.140 [ brakes-rear ] radius = 0.141 Link: http://www.bmwmregistry.com/model_faq.php?id=8 - pwp71 - 11-27-2006 BMW use low rolling resistance car tire. I don't know precisely which. [ tire-front ] rolling-resistance = 8.0e-3, 6.5e-6 [ tire-rear ] rolling-resistance = 8.0e-3, 6.5e-6 What do you think? Link http://auto.howstuffworks.com/tire4.htm - thelusiv - 11-30-2006 I've checked in the changes to the M3 that pwp71 posted on the VDrift-Devel mailing list. Thanks again pwp71. |
