In it's simplest form AutoCal is a way for professional tuners to compete with handhelds. Instead of having to be experts in developing hardware, developing software to create tunes as well as being fantastic tuners, we've taken the first 2 requirements out of the equation.
Effectively we've provided the tools to move the market from 4 or 5 tuners into a market of unlimited professional tuners - all the traditional barriers that have limited the market have gone. Many talented tuners now have the vehicle to deliver their tunes. Their success will be dependent on the services they offer and marketing.
In most cases AutoCal is rebranded by the tuner so you don't even know it's an EFILive product - simply put it's a handheld. Where it differs to traditional handhelds is that tunes can be emailed, data logs can be emailed, and you can tune multiple vehicles.
You wouldn't expect a traditional handheld to allow tunes from another manufacturer to be placed on the device and the same rules apply here.
FlashScan on the other hand is a tuning tool - as a user you are in control of the source of your tunes - you can make them yourself, you can edit them, you can purchase them if you wish to do so.
