FlashScan V3 vs. AutoCal

Hello,


FlashScan V3 vs. AutoCal

How do I know which one should I buy? Is AutoCal for the ready tuning that I received from someone or it's for remote tuning through third party?

Please clarify to me as I didn't get the difference between both products.

my other question is whats the file used with EFI Live is it BIN or CTZ

AC:
your tuner programs it, you plug it in and flash your ECM.
needs to be linked to a FlashScan (your tuner's).

FS:
you edit your own tune and flash it.
you edit other people's tunes and flash them.
your tuner sends you a .ctz file which you flash
