TuneWorks

Plan a race fuel load, reserve, start weight, and projected minimum-weight margin. Calculates from measured inputs without authentication and does not read or save account data. Assumes the entered per-lap consumption applies to race, formation, and allowance laps. Finish weight retains only the selected reserve. Confirm your series weighing rules and validate consumption with real data.

Check speed, RPM, and shift drop from tire size, final drive, and gear ratio. Calculates from measured inputs without authentication and does not read or save account data. Use measured tire diameter when possible. Tire growth and converter/clutch slip can move real-world numbers.

Turn cold, hot, and target hot pressures into the next cold pressure to try. Calculates from measured inputs without authentication and does not read or save account data. This gives a next-test pressure, not a universal ideal. Recheck after the next run.

Calculate cross weight, left/right balance, and front/rear split from four scale pads. Calculates from measured inputs without authentication and does not read or save account data. Measure the car in the same state you drive it: driver, fuel, ballast, and tire pressures matter.

Convert spring rate and motion ratio into wheel rate for setup comparisons. Calculates from measured inputs without authentication and does not read or save account data. Wheel rate compares spring changes. It does not account for bars, bump stops, tires, or aero load.

Estimate injector size from horsepower, fuel type, injector count, and duty cycle. Calculates from measured inputs without authentication and does not read or save account data. This is a sizing estimate. Confirm with your tuner and fuel pressure data.

Convert AFR and lambda across gasoline, E85, methanol, and race fuel scales. Calculates from measured inputs without authentication and does not read or save account data. Use this as a conversion reference. Tune targets depend on fuel, engine, load, and calibration strategy.

Estimate front brake bias from piston area, rotor size, and pad friction. Calculates from measured inputs without authentication and does not read or save account data. This estimates mechanical bias. Tire grip, weight transfer, ABS, and balance bars still matter.

Compare tire diameter, circumference, ride height, and speedometer change. Calculates from measured inputs without authentication and does not read or save account data. Actual mounted diameter changes by tire model and pressure. Use manufacturer specs when available.

Check camber and total toe against broad autocross and track baseline ranges. Calculates from measured inputs without authentication and does not read or save account data. This is a baseline checker, not a vehicle-specific prescription. Tire wear and driver feedback decide the next step.

Compare two laps or sector sets and see the best theoretical lap. Calculates from measured inputs without authentication and does not read or save account data. Use sectors from timing, video, or data logs. Compare similar conditions before blaming setup.

Calculates an ethanol blend for a fresh tank, existing fuel, correction, or ratio without authentication or account-data access. Percentages are 0–100 and all volumes use the selected unit. Source ethanol contents are measured values. Fresh mode requires finalVolume; existing mode requires finalVolume, currentVolume, and currentEthanol; correction mode requires tankCapacity, currentVolume, and currentEthanol; ratio mode requires no volumes.

Provides understeer/oversteer setup guidance without authentication or access to TuneWorks account data.

Interprets inside, middle, and outside tire temperature readings without authentication or access to TuneWorks account data.

Provides a bounded shock/damper adjustment recommendation without authentication or access to TuneWorks account data.
