doesn't use accelerometers, so road conditions will not affect your
results. It uses the "rolling" chassis dynamometer method to
measure your vehicle's horsepower and torque. You won't be required to
start your dynamometer testing from a complete stand-still. Now you can
perform your analysis in the gear that is best for your vehicle--not the
testing equipment.
How accurate is the "rolling"
chassis dynamometer method? Of the two methods (crankshaft or chassis) the
"rolling" chassis method produces the most usable results. This
method will show you what the net horsepower and torque are at the driven
wheels; after the frictional losses from the clutch/torque converter, the
driveshaft, half-shafts, the differential, air resistance, and drag. We
have tested and proven our methods accuracy through several tests against
very expensive roller-based dynamometer equipment.
What sets our performance analysis
software apart is that the results are corrected for environmental
variables using the SAE J1349 standard and built in vehicle profiles.
Using the current environmental variables
(humidity, elevation, and temperature) we can correct the results to
insure the most accurate and consistent results. Correcting for
environmental variables is not enough in the case of force induction
vehicles. The SAE formulas are made for normally aspirated vehicles. We go
one step further and correct for forced induction as well. Without these
corrections your torque and horsepower readings would be inaccurate from
day to day and region to region.
SpeedTracer makes inputting your vehicle
profile easy because it has most vehicle profiles built in. If your
vehicle's profile is listed, simply select it and begin your performance
analysis. In case you have special modifications to your vehicle, you can
change your vehicle profile to take those into account too. You can also
create and modify vehicle profiles to suit your needs.
How does it work: 1) set the
environmental variables so the proper corrections can be made; 2) select
your vehicle profile; and, 3) run your vehicle to its full potential and
see your results. It's that easy. |
