Tuning Master

Tuning Master is a drag racing tuning simulator for people who like turning wrenches and reading data. Start with a tired street car and $2,500, then build, tune and race your way from a 15-second commuter to a 7-second door car. BUILD IT • Eight fictional cars to build: light coupes, muscle cars, a turbo all-wheel-drive four, a front-drive hot hatch, a pickup truck and a mid-engine exotic. • Bolt-ons to full race builds across 18 part slots: intakes, headers, superchargers, turbos, intercoolers, nitrous, fuel systems, engine management, traction control, gearboxes, clutches, axles, tires, suspension, aero, tubs and weight reduction. • Engine builder: set bore, stroke and compression, then choose heads, cam, block, crank, rods and pistons. Every part has a strength limit, so power always finds the weak link. • Swap engines between cars, convert drive layouts and paint your build. TUNE IT • Real ECU tables: VE, target air/fuel ratio, ignition timing and boost by gear, edited cell by cell in a spreadsheet-style editor. • A piggyback tuner for your first boost, then a standalone race ECU with two-step, flat-shift and traction control. • Gearing, final drive, converter stall, clutch, launch rpm, shock settings, anti-squat, wheelie bars and tire pressure. • Weak-link gauges show knock margin, fuel capacity, mixture and part strength as you move every slider. PROVE IT • Run dyno pulls to see power, torque, boost and wideband AFR across the rev range, with tuning hints and overlays against your last pull. • Take it to the strip on four levels of track prep, from bare asphalt to race-day glue, with weather and density altitude. • Stage, watch the tree and launch. Wheelspin, weight transfer, shifts and breakages are all simulated. • Read the time slip, crew chief notes and a full datalog of every pass, then go back and tune again. RACE AND RUN A SHOP • Climb a ladder of twelve racers for cash to fund your next part. • Run a tuning shop: customers bring their cars with a goal and a budget, and you get paid for hitting it safely. Build reputation for bigger cars and bigger checks. • Parts wear with every pass. Keep up with maintenance or pay for it in broken rods and axles. No ads, no accounts and no internet connection needed. Your career saves on your device. All cars, engines and racers in Tuning Master are fictional.
