Instructions for downloading and viewing the raw dyno data.
* Download and install the dyno data viewer.
* Download PencilGeek's dyno data file here.
* Run the Dynapack Viewer.
* Press <F8> (Folders). I don't think the function keys actually work here, so place the mouse over the <F8> key on the screen and left click.
* Press the "Import Files" button.
* Locate the file you downloaded and saved on your computer. Highlight it, and click "Add" then "OK"
* Select the "Vehicle Folder" on the left of your screen where you just imported the dyno results. On my system, it was in my TEMP directory, so the folder name is "TEMP"
* Double Click on "PencilGeekDyno-2008-05-08." When the "Load Data" dialog box is displayed, select "Source"
* When promted to overwrite the current vehicle setup, select "YES"
* When the dyno chart is first displayed, you'll want to change a few settings (if they are not already set). Select Setup->System. Look under the "Power Correction Standard." Change the Standard to "SAE (adapted)" setting.
* In the "Units" area, select your preferred HP/TQ, PS/KW/NM settings -- according to how prefer to view this data.
* Makes sure the "Correct Torque with Power Correction" checkbox is checked (bottom right of screen)
* Press F10 -- OK
* Change the display: Display->Flywheel Torque Graph.
* Look at the various other display graphs as well.
