Hello there i decided to create Nismo Z-Tune version of R34 GTR for my own offline races stock R34 should be about 1600kg, AWD, 2.6L L6 twin turbo engine, "276 HP (206 kW) @ 6800 rpm and 260 lb·ft (353 Nm) @ 4400 rpm. By the end of production, power levels had gone up to around 276 HP (206 kW) @ 6800 rpm and 289 lb·ft (392 Nm) @ 4400 rpm"- wiki Other source: L6, 332 PS (244 kW, 392 Nm) (advertised as 276) In game Nissan is V-spec version has 325 HP and 392 Nm of torque - Vspec version is just different aero parts ... however real Godzilla has been build in just 20 specimen they call it Z-tune http://www.nismo.co.jp/Z-tune/contents_e.html 368KW (500 HP), 540 Nm of torque 1600 kg of weight - and here it comes I'm trying to figure it our how power settings are working in AC there are 2 files that i found: Power.lut and Power_ORl.lut Power.lut: 0|125 500|125 1000|130 1500|155 2000|172 2500|200 3000|206 3500|230 4000|227 4500|223 5000|228 5500|225 6000|222 6420|211 7000|190 7500|173 8000|165 8500|106 9000|0 I Can't figure it out what are those values Kilo Watts ? Horse Power?, Wheel Horse Power?, Torque ? Power_ORl.lut: -3000|100 -250|100 0|100 500|120 1000|124 1500|129 2000|197 2500|238 3000|281 3500|306 3750|310 4000|304 4500|300 5000|302 5500|288 6000|280 6500|274 6700|267 6800|264 7000|256 7250|246 7500|213 8000|0 Same its more similar to Torque curve but still it lacks of torque... Second problem lies into tyres .... Z-tune had 265mm wide tires meanwhile stock/vspec/vspecII had 245mm wide ... I'm trying to create a little bit more sticky tires for that version however my lack of skills and language barrier WIDTH=0.245 RADIUS=0.3266 ; tyre radius in meters RIM_RADIUS=0.254 ; rim radius in meters (use 1 inch more than nominal) ANGULAR_INERTIA=1.62 ; angular inertia of front rim+tyre+brake disc together DAMP=500 ; Damping rate of front tyre in N sec/m (values usualy from 200 to 1400) RATE=358000 ; Spring rate of front tyres in Nm DY0=1.2798 DY1=-0.050 DX0=1.2368 DX1=-0.046 WEAR_CURVE=street_front.lut ; file with lookup table to call SPEED_SENSITIVITY=0.002563 ; speed sensitivity value RELAXATION_LENGTH=0.0739 ROLLING_RESISTANCE_0=12 ; rolling resistance constant component ROLLING_RESISTANCE_1=0.000505 ; rolling resistance velocity (squared) component ROLLING_RESISTANCE_SLIP=5248 ; rolling reistance slip angle component FLEX=0.000679 ; tire profile flex. the bigger the number the bigger the flex, the bigger the added slipangle with load. CAMBER_GAIN=0.158 ; Camber gain value as slipangle multiplayer. default 1 DCAMBER_0=1.1 DCAMBER_1=-13 ; D dependency on camber. D=D*(1.0 - (camberRAD*DCAMBER_0 + camberRAD^2 * DCAMBER_1)) , camberRAD=absolute value of camber in radians FRICTION_LIMIT_ANGLE=8.1 ; Friction limit angle. XMU=0.28 PRESSURE_STATIC=35 ; STATIC (COLD) PRESSURE PRESSURE_SPRING_GAIN=10200 ; INCREASE IN N/m per psi (from 26psi reference) PRESSURE_FLEX_GAIN=0.6 ; INCREASE IN FLEX per psi PRESSURE_RR_GAIN=1 ; INCREASE IN RR RESISTENCE per psi PRESSURE_D_GAIN=0.006 ;loss of tyre footprint with pressure rise. PRESSURE_IDEAL=40 ;Ideal pressure for grip FZ0=3208 LS_EXPY=0.89 LS_EXPX=0.89 DX_REF=1.20 DY_REF=1.20 FLEX_GAIN=0.183 FALLOFF_LEVEL=0.87 FALLOFF_SPEED=4 Which value i should change to get more sticky tyres P.S i tried to change width Can You guys tutor me?
