Private League Derivative for TTM at THR===========================Base car comes from v3.0 of this Original Mod:https://www.overtake.gg/downloads/ford-sierra-cosworth-rs500-pack.24027/===========================TTM version is derived from 2021 THR League Proposal Physics Changes by JackCY===========================Updates by THR for TTM 2024 season:v3.0.2 Bugfix:- tyres.ini: corrected DY_REF and DX_REF of HX compound==== Physics (on top of JCY physics) ====- drivetrain.ini & setup.ini: configured all 4 gearboxes that were Group A homologated for RS500 in Group A competition by F.I.S.A. (5- & 6-speed)- final.rto: added all 38 final ratios that were Group A homologated by F.I.S.A.- colliders.ini: new ground collider- brakes.ini: added brake temperature modelling- dash_cam.ini: re-positioned to match 190E and M3- electronics.ini: upgraded ABS to 4-channel specification again to match TTM-spec M3 & 190E- tyres.ini: --- added new Extra Hard (HX) tyre compound--- reverted thermals of S, M & H tyres to Kunos M3 Gr.A92 specification- ext_config.ini from v3.1 and expanded to add dedicated highbeam headlight emissive, 1 reversing light, and some better dash lights. No rear turn signals because the tail light object to texture mapping makes it impossible to configure skins:- original real-life skins by NWRAPGraphics- added real-life DTM 1988-89 skins by =LM=908GTS:https://www.overtake.gg/downloads/ford-sierra-cosworth-rs500-skins-pack.32952/=== Physics basis: 2021 THR Proposal by JackCY ===DTM regulations added weight and mandated a restricter on the turbo's inlet to reduce horsepower. Much more of a fair match to the E30 M3 and 190E.Details below:=== Equal to existing DTMs ===- ABS_V2 1 channel ABS [revoked in THR TTM update]- brakes 2500- cockpit adjustable balance- handbrake 600=== Setup ===- front spring step 20- no fast dampers adjustment in line with existing DTMs- damper rate ranges and steps in line with existing DTMs- older version final drive ratios = better adjustment and top speed- BRAKE_POWER_MULT available- both older and newer version gearsets- ARBs changed to steps in line with existing DTMs- front and rear adjustable aero=== Engine ===combined and adjusted power curves of older and newer version to fit better with found data, 329.5 bhp/424.9 Nm at the wheels, gives power to weight ratio in line with other DTMs now 295.52 rwhp/tonne, power and torque at engine: 378.7 bhp/488.4 Nm.reworked turbo and turbo drop offfuel consumption to match other DTMs and expected engine power efficiency=== Car ===- found real weights, changed to 1115 kg including driver- default fast and slow dampers in line with existing DTMs- aero fixing the scientific notation of numbersfront and rear DTM aero- bumpstop distances raised in line with existing DTMs- lower clutch torque for easier starts- AI shifting- drivetrain version and extra data- disabled debug logging- RPM led blinking enabled=== Remaining ===- the RPM analog dial is off, same goes for Ks Alfa=== Dragstrip 500m ===13.4s 211 km/h Ford Sierra RS500 1050kg original v303 (way too OP power, aero, brakes, even fuel)13.6s 207 km/h Alfa 15513.8s 209 km/h Ford Sierra RS500 1115kg updated (this version with all the changes)13.9s 208 km/h BMW E3013.9s 207 km/h Mercedes 190E=== Performance ===power/tonne = acceleration, equal to Alfa, higher than E30 and 190Etop speed higher than all stock content DTMsdownforce/weight similar to E30, good weight balance car, a lot of power and top speed but as the real thing it has worse aero than newer DTMs
