This document is intended to assist EFILive customers with the basic operations
and steps necessary to work with 2010-2018 6.7L Cummins supported vehicles.
CM2200 & CM2350B ECM Overview
Due to the CM2200 and CM2350B ECM's restrictive architecture, Cummins 2010+
ECMs cannot be read via the OBD-II Port. These ECMs can only be read by
opening the ECM and soldering to the CPU debug port using expensive 3rd party
tools.
Customers will need to obtain a suitable base file for editing and flashing. A
selection of EFILive compatible base stock files are readily available on the
internet or custom files may be purchased through organizations that have the
necessary hardware and software to create personalized base files.
There are two ECM types; EFILive refers to these as CMD and CME.
Because you cannot read the existing tune in the ECM it is important you select
the correct base tune to suit your vehicle.
RSA Digital Signature
In early 2009 Cummins ECMs were manufactured with higher levels of security
consisting of an RSA Digital Signature on the calibrations. The RSA Digital
Signature does not prevent the flashing of stock tunes, it ONLY prevents the
flashing of modified tunes, so to flash a modified tune the Digital Signature must
be switched off.
The EFILive ECM flash process manages the removal of the Digital Signature via
OBD-II flashing in the following circumstances:
In vehicle and bench harness flashing.
In vehicle flashing for CM2100 and CM2200 controllers requires the BootRSA
Patch file process to remove the digital signature. Please refer to the Cummins
Boot RSA Patch User Guide.
