Can you try reading the ECM using pass-through instead ? (eg from your computer).
Use the Auto-detect function in the Read options as well, then if it still fails can you please locate the trace file of the failure and Email it to support@efilive.com

Read/Flash Trace Files (V8 only)

When the EFILive application reads or flashes a controller the details of the read/flash process may be saved in trace files for diagnostic purposes.
Trace files are created on your PC or laptop in the folder: \My Documents\EFILive\V8\Trace and are named using the following naming convention:
YYYYMMDD_HHNNSS_T_CCC.htx
Where:

  • YYYYMMDD: is the year, month and day that the trace was recorded.
  • HHNNSS: is the hour, minute and second that the trace was recorded.
  • T: is the mode and is one of R=Read F=Full-Flash W=Cal-Flash.
  • CCC: Is the controller type
  • htx: is the file extension.

An example trace file name might be: 20180504_214334_F_E38.htx which contains a trace of a Full-Flash attempt on an E38 controller on May 04, 2018 at 09:43:34pm.
