What it does
Timeslips
60 ft, 330, 1/8, 1000 and 1/4 mile with trap speed, plus 0–60, 0–100, 60–130, peak g and a speed trace — every run graded on GPS quality.
Horsepower
Estimates from trap speed, ET and road-load physics, with a coast-down mode that measures your car's real drag.
Trucks & towing
Hill Pull, Downhill Brake Test and Hill Climb score a tow on a real grade.
Laps
Circle track or road course: lap times, a track map drawn from your own line, and corner-by-corner verdicts against your best lap.
Engine gauges & scanner
With an OBD-II adapter: a custom gauge dash, trouble codes in plain English, readiness monitors and every live channel the car reports.
Christmas tree
Sportsman or Pro tree on your phone with reaction times, or let Launch Detect start the clock.
