So you can compare measurements on different days. Available standards : DIN (Europe), SAE (America), JIS (Japan), CEE (Europe) and ISO (International).
- Charts of wheel and engine horsepower / engine speed. With automatic detection of the engine rev limiter (or throttle release) in order to get a curve starting from low revs up to the red line, as on a chassis dynamometer report.
- Charts of wheel and engine torque / engine speed.
- Use of your phone accelerometer at its maximum frequency. Even 200Hz (eg LG Nexus 4) or more if your phone allows it.
- Use of advanced signal processing for smoother curves without reducing the acquisition frequency.
- The results are grouped by engine "Setup" that you can define yourself
- Possibility to enter multiple gear ratio for each car
- Curves are shown in a full screen interactive graph that lets you know the exact values ​​at any point with an extraordinary precision.
- Individual choice of units from a large number: Hp, Ch, Kw, Nm, Ft.Lb, mKg, Mph, Km/h, m, ft, G, m/s≤, psi, inHg, mBar, °C, °F
- Timer test mode to measure your 0-60mph, 0-60ft, 0-1/8mi, 0-1/4mi, 0-100km/h, 0-20m, 0-200m, 0-400m, and much more.
- Excellent measurements consistency for accurate comparisons.
- Detailed reports of dyno runs and timed runs with specific information for each type of measurement.
- Export reports in Tab Separated Value format and PNG.
- Compatible with most tablets (GalaxyTab 10.1, 8.9, Nexus 7, Nexus 10 ...) and high-resolution screen phone (Nexus 4, Nexus 5, Galaxy S3/S4/S5, Galaxy Note, Galaxy Nexus, HTC One X. ..)
