A simulated engine on a dyno, run by a standalone ECU you tune yourself. Change the fuel map, the timing or the boost and watch what happens to the power curve, the mixture and the knock sensor. It behaves like the real thing. The engine model runs every combustion event. Lean it out and it misfires. Add too much timing and it knocks, then cracks a piston. Fit bigger injectors without telling the ECU and it floods. THE ECU - Fuel VE, lambda targets, ignition, boost target and wastegate duty, idle, warmup, cranking, accel enrichment and dead times - Closed loop, knock control, rev and boost limiters, auto learn and "Fix from pull" - Select cells, drag curves, type values, interpolate and smooth, in a grid or in 3D - Lay the data log over any table and see which cells ran lean or knocked THE ENGINES - Ten engines: fours, a flat four, straight sixes, V6s and V8s - Naturally aspirated, turbo, twin turbo, supercharged and nitrous - Nearly 100 parts: injectors, pumps, lines, regulators, turbos, housings, wastegates, blowers, cams, pistons, rods, head gaskets and fuels, E85 included THE DYNO - Hold any rpm at any throttle, or do a full wide open throttle pull - Power, torque, mixture, boost and timing on every run - A full data log you can zoom into - Engine health: knock, over-revving, boost and heat all wear parts out, and some failures are sudden CAREER MODE Start with a rented unit, a small dyno, a stock project car and $1,500. Customers bring in cars with vacuum leaks, tired fuel pumps, stuck wastegates, burnt valves and lying sensors, or ask for a power target on a budget. Find the fault, fix it, tune it and hand it back for a test drive that grades your work. - Eleven kinds of job, from base tunes to E85 conversions, race class builds, blown engine rescues and cars three other shops couldn't fix - Four rival shops with owners and an 8-week season. Beat them at Dyno Day and their customers switch to you - Cars come back weeks later. A tune too close to the edge breaks on a hot day and returns on warranty; a safe one turns the customer into a regular - Intermittent faults that only show hot, cold, under boost or near redline - Eight story customers who bring the same car back chapter after chapter, with your parts and tune still on it - Diagnostic tools, a bigger dyno, more bays, weather, deadlines, rent and 31 achievements DAILY CHALLENGE One broken engine a day, the same for every player. Nine hours on the clock to find the faults and tune it, then see where you land on the leaderboard. Tuesdays and Saturdays are free on the Turbo Four. LEARN A guided tutorial takes a broken project car from flooding on the stand to a full tune. Twelve more lessons cover VE tuning, MBT, knock, boost control, injector swaps, fuel system limits, E85, nitrous, big cam idle and cold starts. GAME CENTER Leaderboards for the daily challenge, peak horsepower and horsepower per litre. A pull only counts if the engine is still alive five seconds later. FREE AND PRO The Turbo Four, the guided tutorial and the Tuesday and Saturday daily challenges are free, with every part and every table. Tuning Simulator Pro is a one-time purchase that unlocks all ten engines, custom builds, every lesson, Career mode and the daily challenge every day. No subscription, no ads, no account.

=== TEXTES APP STORE (FR) - v1.2.8 === Sous-titre (29/30) : Construisez le moteur, roulez Texte promotionnel (162/170) : Construisez votre moteur pièce par pièce, réglez-le, puis conduisez-le : plus de 1 800 véhicules, routes, circuits et un pays ouvert à explorer. Sans compte. Mots-cles (97/100) : mécanique,piston,turbo,vapeur,Stirling,hybride,diesel,boîte,garage,camion,tracteur,V8,wankel,auto Nom de l'app : SIMULATION MOTEUR Description (2446/4000) : SIMULATION MOTEUR n'est pas un jeu de course. C'est un simulateur de mécanique : vous construisez le moteur vous-même, pièce par pièce, puis vous allez voir ce qu'il vaut sur la route. ▬ LE MOTEUR SE CONSTRUIT Mono, en ligne, V, VR, W, boxer, Wankel, H, U, X, radial et rotary radial : jusqu'à vingt-quatre cylindres. Alésage et course au dixième de millimètre, soupapes, distribution, alimentation, turbo ou compresseur, échappement, calage du vilebrequin, régime de rupteur. Chaque réglage se lit tout de suite : courbes de couple et de puissance, et coupe animée des pistons, bielles et soupapes à la vitesse réelle du moteur. ▬ PLUS QUE DES MOTEURS À ESSENCE Diesel, moteur à vapeur avec chaudière, moteur Stirling, turbine, électrique et hybride. Chaque famille a ses propres réglages, ses limites et ses façons de casser. ▬ PUIS IL SE CONDUIT Vue intérieure avec compteurs, vue capot ou vue extérieure. Boîte manuelle avec embrayage (qui s'use), ou automatique. Les propulsions partent en glisse quand on insiste : il faut contre-braquer. Soleil, pluie, orage, heure et température se règlent. La nuit tombe pour de bon : à vous d'allumer les phares. ▬ PLUS DE 1 800 VÉHICULES Voitures, motos, quads, camions, autobus, tracteurs, chars et trottinettes. Chacun a sa fiche : masse, traînée, pneus, freins, étagement de boîte et son moteur, de la citadine trois cylindres au W16. Concessionnaire, garage, atelier, banc d'essai à rouleaux, réglage de la boîte, de l'aérodynamique et de l'ABS. L'huile s'use. Remorque et caravane s'attellent, et se sentent. ▬ ROUTES, CIRCUITS ET GRAND TOUR Autoroute avec aires et péages, route de campagne avec carrefours et ronds-points, route de montagne, montée du col, ville avec feux et stops, circuits fermés et tout-terrain. Le GRAND TOUR : un pays ouvert à explorer librement, avec sa carte, ses villes, sa mer et sa montagne. Chrono et adversaires sur les circuits. ▬ SANS COMPTE Pas de compte à créer, pas de connexion pour jouer. Vos véhicules, moteurs et réglages sont enregistrés sur votre téléphone. Le jeu affiche des annonces, seulement au retour au menu : jamais au volant, jamais en pause. Elles ne sont personnalisées que si vous autorisez le suivi. Un achat unique et facultatif supprime les annonces. ▬ LANGUES Français, anglais, allemand, espagnol, italien. Toutes les marques, séries et appellations sont fictives. Toute ressemblance avec des véhicules existants serait fortuite.
