1:Can my device I already own be used to flash your files.

1: Yes most of the time your current device can be converted to flash our files. There are limitations to it as well as somethings that may need to be done to work. But most of the time they can be used on multiple trucks. Please contact with concerns/questions.

2: Autocal VS Flashscan.

2: Autocal is a cheaper more common option for a end user wanting to tune a few vehicles from the same tuner. The device is locked to tuner so cannot flash other tuners files without unlinking and relinking autocal.

2:Flashscan More expensive option has less limitaions. Can flash multiple tuners files without the need to unlink/relink. Usually a more viable option for shops doing multiple vehicles constantly.
