We have had several SERIOUS 6.7L Cummins ECM failures in the last 24 hours. We are currently investigating. The common thread is all were previously tuned with SMARTY. Our development team are currently working through the issues, but can verify that ORIGINAL stock tunes and the latest public release software DO NOT cause failure. We will provide further updates as more information comes to hand.

just did 2 this weekend with no problem both had smarty's on them previously... thank god nothing happend!! hopefully figure out why this is happening!

Also did a 5.9 that use to have a bullydog and got my first experience with that...lol
 
What we know so far, the three trucks that failed were all ones that had been 'returned to stock' by the Smarty programmer.
All are running the ECM OS number 11720300, two were previously 14ME, the other 14TNT.
I don't know MADS update system, you guys would probably have more idea on how old those are and what they've been replaced by.

As others have noted, there is no issues with the current release and real stock tunes, others are saying that have been using the later Smarty 'returned to stock' files ok as well. Initially we suspected something must have been wrong with our update, however it looks like just a bad co-incidence that three trucks happened to be running the same 14 Smarty release, this seems to be the only common link.
 
We have updated our software with additional warnings. The Public Release software (Apr 03) is now available for download from our website. Download Software

For Cummins, this release adds additional warnings for incomplete files, and updates the Cummins ECM Reference Notes.PDF which can be found via the menu selection Start>All Programs>EFILive>V8>Documents>Cummins ECM reference notes.pdf

Many box tuners DO NOT return the ECM to stock even on the stock setting.

Whilst some incomplete files may be suitable for flashing, EFILive is now advising against this. Each box tuner has their own flashing routine, and it is impossible for us to know and understand each and every method they use for each of their products, software versions and operating systems. Consistency DOES NOT EXIST, therefore customers SHOULD NOT TAKE THE RISK.

Customers will need to obtain a true stock file either from their EFILive reseller, the tune library or their dealership.
