Windows Dyno Software
Auterra's Dyno-Scan for Windows dynamometer features include horsepower and torque
measurements, acceleration tests, and fuel mileage. The remarkable dyno features
are are an Auterra first! Never before has a product combined the power of a
diagnostic scan tool with a performance measuring dyno package. Auterra

Did that engine modification really increase horsepower? What is my vehicle's
0-60 time? How fast is my vehicle on the 1/4 mile? Auterra's Dyno-Scan measures
this and a whole lot more!
The Dyno-Scan software records speed and RPM signals while the vehicle
accelerates through the RPM range. With vehicle and environmental parameters
entered, such as vehicle weight, drag coefficient, altitude, and air
temperature, the software creates horsepower and torque curves.
Environmental factors are corrected for using the industry standard SAE
J1349. This dyno correction factor is used to standardize the horsepower and
torque readings, so that the effects of air pressure, humidity, elevation, and
temperature are removed from the measurements. With this dyno correction factor
applied, measurements from a vehicle dyno'ed on a cold day in Denver will
produce the same results as a hot day in San Diego.
Vehicle factors, such as drag coefficient, frontal area, and vehicle weight,
are also compensated for within the software. This means regardless of whether
your vehicle has the aerodynamics of a Ford F150 or a Porsche 911, the software
correctly measures power and torque.
