I can download the initial spark software and all that but when I link the actual flashcal to my computer's usb port I get a "usb serial port" failure message. It did allow me to download the TPMS upgrade and says ready to use. Anyone else have this issue and know how to remedy it? Not sure of it's safe to use or not. FYI, I am not computer savy.

 

U need to download a driver for the flashcal uninstall spark and reinstall it then reset ur pc then plug in the flashcal and it should boot up normal

Also try a different port or a different cable

 

Sorry I do not know computers. Uninstall the spark software and reinstall it. What do you mean by reset my pc? You mean restart after I install Spark? Thanks btw.

 

Yes restart the computer also use a different usb outlit from ur pc

 

Ok, I will try that. Thanks.

 

Ok this did not work. Guess I will email tech support.
