Why are there two versions of EFILive's software (V7 and V8)?
We are currently in a transition phase from the current V7 software to the new V8 software. The new V8 software supports the standalone features: BBL (Black Box Logging), BBR (Black Box Reading) and BBF (Black Box Flashing) collectively known as BBx. V8 will eventually include new and improved Scan-Tool and Tune-Tool software. However, until then you must continue to use the current V7 software for pass-through logging and tune file editing. Even if you don't intend to use the BBx features of the V8 software, you must still download and install it because it contains the FlashScan and AutoCal firmware updates.Those firmware updates are required even if you are using the V7 software exclusively.
