This will be a push for TunerPro since all files are community made!

I'm sure more will follow, right now EPA is hitting the diesel tuners so it looks like an effort to avoid legality the software is changing before it hits them. EFI Live is not based in USA, so EPA went after diesel tuners using it.

From the EFI Live forum.

Diesel tuning restrictions for USA customers
As many of you may have heard or read about in the last few days, our next software update will contain restrictions to the available calibrations for diesel engines. More specifically for the LMM and 6.7L Cummins that have a DPF system fitted.
USA based customers will no longer have access to alter the calibrations affecting the operation and diagnostics of these emissions controlling components. For EFILive users outside of the USA this restriction will not apply and you should notice no change in what you can and can't tune. There will not be separate USA and International versions of the software, there will still only be one version for downloading.

We would like to make this thread the official place to ask questions regarding these changes, however, if the questions are nothing more than you venting your dissatisfaction about this then the post will be removed.

Please read THIS as a starting point.

Based on the ongoing discussions in this thread, below is a few key items, an FAQ of sorts that you might miss reading through the various pages.


  • Your existing V2's, Autocals etc will continue to work fine with the current public releases, V7.5.7 Build 211 & V8.2.1 Build 203.
  • If you update the firmware in the V2/AC to that in the next release it might not work correctly with older software, it's always been this way with each new release anyway.
  • For any existing tune files you have, the tuning changes will remain untouched, all new tune files created with the next update will not have access to the DPF related functions for USA customers.
  • It's still your choice if you update or not, we aren't forcing you, we aren't sneaking the restrictions in.
  • There will only be one version of the EFILive software, there is no secret 'international' version USA users can install.
  • The restrictions have nothing to do with your registration details on the forum or with your V2 warranty cards.
  • Sending EFILive staff Emails and PM's asking how to get around this will simply be ignored, no response whatsoever.
