EFILive V8

Due to the new security/encryption option in this release, all tune files saved using this release will no longer be compatible with older versions of the V7 or V8 software. If you distribute tune files to other users (i.e. your customers), the recipients must be:

  • using this version or a later version of the V7 and/or V8 software.
  • using this version or a later version of the V2 and/or V3 firmware.

AutoCal users should only update software and firmware at their tuners specific request. Updating to software and firmware versions higher than your tuner may lead to your tuner being unable to offer you support until they update.



  • When loading a tune file for comparison, if the alternate tune file's operating system is not supported, either via an EFILive defined *.cam file or a user defined *.cax8 file, then no comparison is attempted.
  • Changed the "Copy as Lua Source" hot key from Shift+Alt+C to Ctrl+Alt+C to prevent clashing with the tune tool window's "Capture Screen to Clipboard" hot key which is also Shift+Alt+C.
  • When opening calibrations using the favorites hotkeys (Ctrl+Shift+0..9), sometimes the wrong calibration was opened, sometimes no calibration was opened.
  • Fixed configuration/setup problems with speedo calculator.
  • Speedo calculator window now closes when the parent tune file window is closed.
  • Fixed fault where scripts running from the command line were not retrieving FlashScan's/AutoCal's license number correctly - which caused problems when applying security options to tune files.
  • Added Cummins injection timing calculator.
  • Added cax8 section [AddressOffset] to allow similar cax8 files to share address lists where blocks of calibration addresses differ by the same offset.
  • Added option when selecting scan-tune PID links to override the unit matching and allow any PID to be linked to any axis, regardless of units. This option is primarily to allow PIDs to be selected to link with tune axis that have no units.

Calibration Updates:

  • GM T43
  • GM E80
  • GM E78
  • Cummins CME (CM2350B).
  • Cummins CMF (CM2450B).

Known Issues:

When logging DMA PIDs (i.e. PIDs whose names end with "_M" or "_DMA"), if the ignition is switched off for an extended period while data logging but data logging is not terminated, then when the ignition is switched on again the data log automatically continues. However, the DMA PIDs may no longer return valid data.

Workaround: EFILive recommends stopping the data log and restarting the data log when switching off the ignition for extended periods.
