Will Dynamic Dyno work with my vehicle? If you have a working 12V DC
accessory outlet and your vehicle has a gasoline engine, Dynamic  Dyno should
work. Dynamic dyno has been tested successfully with Acura, BMW, Ford,
Honda, Mazda, Mitsubishi, Nissan, Subaru, Toyota, Volkswagen, and Volvo cars.  
The table below lists the makes tested and the quality of the spark plug signal.  










What other things not included in the kit do I need?  
A recorder with a microphone input to record the run (an audio tape
recorder, digital voice recorder,a video recorder, or a laptop with a sound
card).
A Windows 98, 2000, ME, or XP PC with a sound card and serial port to
run the software. The minimum recommended system requirements are
Windows 98, Pentium II 400MHz, 64MB ram, 8MB video memory, and 62.5
MB of hard drive space for Dynamic Dyno installation.
The table below shows how long it takes to process a typical .wav file with different
computer configurations.









What information do I need to input into Dynamic Dyno?   Vehicle weight
including passengers, an estimate of the amount of fuel needed to fill up the gas
tank, final drive ratio, gear ratio, tire radius, drag coefficient, frontal area, air
temperature, dew point, and pressure.  Some of these values have a very small
effect on the calculated horsepower and torque.  Download the user's manual if
you want more information on the effect of the different factors and suggested
internet sites for finding them.

What if I don’t know and can’t find my vehicle's transmission and final drive
ratios?  A program is included with Dynamic Dyno called Gear Ratio & Final
Drive Ratio Estimator. You simply drive at a constant speed in the gear you are
doing your runs and write down the RPM value for that speed (for example
3000rpm at 30mph). After you enter the rpm value and corresponding speed,
Gear Ratio & Final Drive Ratio Estimator gives you equivalent gear and final drive
ratios to enter into Dynamic Dyno.  More detail can be found in the owner's
manual.

What if I don’t know and can’t find my vehicle weight?  You may be able to
have your vehicle weighed at a commercial truck weigh station for a small fee.
You can also guess a weight and use the same weight for all your runs. The
actual horsepower values will be incorrect but you can still see the effect a
modification has made to the power curve.  


Where can I find current weather conditions (temperature, dewpoint, and
altimeter pressure) for my area?  24 hour weather information can be obtained
from the National Weather Service including temperature [F], dewpoint [F], and
pressure [altimeter inHg] at http://weather.noaa.gov/index.html .
