As the emission requirements have changed over the years, the ECM used to control the 6.7 Cummins in the newer Ram trucks has gotten more and more difficult for tuning companies to offer programmers. Even today, there are still only a hand full of companies that have late model tuning available for the 6.7.

There have been rumors for the past few years as to whether EFILive was going to offer tuning or not for the late model Rams. Today, they released the following statement:

“EFILive is pleased to announce that our beta program to support the Cummins 6.7L 2010-2012 ECM (CM2200) and the Cummins 6.7L 2013+ (CM2350B) has commenced.   Like our support for the LML Duramax, we’ve had to make some technical adjustments to support these platforms compared to our usual method of platform support.

Re-flashing of both pickup and C&C tunes is working successfully, taking between 7 to 8 minutes on both ECM types, a significant improvement over the factory tool which generally takes about 25 minutes on the 2013+.

Mapping for the 2010-2012 ECM, and the 2013+ ECM has been finalized over a select number of operating systems, and the Anti-Tuning disable patch on the 2010-2012 has been implemented in an identical fashion to the CM2100 2007-2009 6.7L ECM.  Scan tool functionality is also being tested.

Due to the ECM’s architecture, 2010-2015 Cummins support does not adhere to the typical “EFILive process” for tuning supported vehicles.  EFILive generally requires customers to first read and save their ECM file, then edit the calibrations before finally flashing the modified tune back into the vehicle, however it is not possible to read the CM2200 and CM2350 ECMs via the OBDII Port.  Customers will need to obtain a base file for editing and flashing purposes, and It is expected that a library of stock tunes will be available prior to public release.

CSP5 for both ECM types is planned, however will not be available for our initial public release.  Like CSP5 for existing platforms, the space constraints of each ECM will limit the parameters made available for switchable tuning.

Given the ECM controls both engine and transmission functionality for 68RFE equipped vehicles, transmission support is likely, however at this point of time development for transmission parameters has not commenced.”

While they are still working on Beta testing of their tuning, being able to offer beta testing indicates they are close to what they believe will be a final product.

Unfortunately, due to the man hours required to not only finish the development of the late model tuning, but to maintain it, they are discontinuing the 2003 to 2005 SCI development.

We will keep you posted as we find out more. The only people able to Beta test this current version are people on the Beta tester list. As soon as they have thoroughly tested the software, they plan on making a public pre-release version as well. So, stay tuned!
