I have a non-s 3500 and I love it..... but I can't seem to get the Horsepower to display..... the configuration option to amend the Horsepower Calibration is grayed out.... so I tried to save all the data files to the SD card so that I could edit the configuration on a PC with a text editor, expecting there to be a horsepower.afd or horsepower.afc file, but no such file exists. It's as if the AFS3500 has lost that file and that's why the menu item is grayed out.

Is there anyway I can get hold of an example horsepower configuration file so that I can populate it with the data for an IO-360, and then restore it to the 3500? or am I barking up the wrong tree?
