- Drag racers tuning a car between passes
- Worth noticing
- The site says one browser-saved combo can prefill calculators, avoiding repeated entry of weight, tire, and gear data.
Field notes
The calculator library is grouped into ET and horsepower, weather and fuel, engine math, and gearing. Examples include weather-corrected ET, E85 blending, converter slip, and tire-size changes. The site says a single combo saved in the browser can prefill fields such as weight, tire, and gear; it also advertises live air readings for 40 tracks and a separate $39 tuning logbook.
