Introduction
What is EFILive?
EFILive is tuning software and hardware - it is not a tune. Together the software
and hardware give users the tools to write tunes. EFILive does not provide tune
files, tuning advice or support, but do provide software support and hardware
support.

Support Retirement
This document was originally created for DSP
5
and DSP
2
custom operating
systems. Support for DSP
2
operating systems was retired in July 2018.
The DSP
2
custom operating system has not been migrated to V8 Scan and Tune
software.
What is EFILive DSP
5
?
EFILive's DSP
5
custom operating systems for Duramax controllers allows
customers to be able to switch 'on the fly' between multiple tunes, all stored in the
ECM's flash memory
Having multiple tunes instantly accessible means changing tunes to suit different
driving conditions no longer requires the ECM to be reflashed each time you
choose to run a different tune. (E.g. racing, towing, or power limiting.) Simply build
multiple tunes to fill the DSP
5
slots, flash the ECM once and then select your
desired tune through via a hardwired switch at any time.
The ECM can be returned to GM factory condition at any time by reflashing a
stock GM Operating System and calibration into the ECM using the Full Flash
option.
