Figure 27: Parameters for dyno calculator
Only three parameters are required for the calculation:
•
Input Speed Signal:
Choose Vehicle Speed from GenericOBD2
•
Input RPM Signal: Choose Engine RPM from GenericOBD2
•
Input Vehicle Weight (lbs): Enter the vehicle weight in pounds
The other parameters can usually be ignored, but you can try tuning the values for increased accuracy:
•
Input Acceleration Filter Time:
•
Input Accel Calc Type:
•
Input Speed Filter Constant:
The driver generates two measurements that may be assigned to any gauge (section 0) and can be data logged just like any other signal
(section 0):
•
Calculated Horsepower:
•
Calculated Torque:
If you’ve assigned either statistic to a gauge but you’re not seeing values, double-check that you’ve assigned signals for both the Input
Speed Signal and Input RPM Signal parameters. Also try assigning the input signals to a gauge to verify that DashDAQ is actually able to
get a reading.
FUEL ECONOMY CALCULATOR
DashDAQ can calculate instantaneous fuel economy and display the results by distance (miles per gallon) or by time (gallons per hour).
Make sure that the “Statistics Calculator” was selected when reflashing the firmware (section 0) and install the driver on an available
port (section 0).
