I purchased a Curtis 1313-3231 scan tool to help diagnose problems. I would like to be able reset speeds but it wont let me. Is there any way to upgrade either with program on an SD card or by interface on line with my computer?? too many carts at our resort are set to go way too fast ! I use the scanner on a regular basis to help diagnose and fix problems so if there is a cost factor I would be willing to pay a reasonable fee !
