A quick summary as these are the challenges that still need to be worked out, for some this isn't going to be an issue.


  • If you didn't get your own ECM unlocked you'll need to have the ECM set up like a new ECM would need, eg VATS, Injector Trims etc....I am not sure how this is done on the L5P.
  • You need to get a stock file (probably via TIS) and it will need to be configured to work with EFILive. (currently this requires a lot of manual manipulation of the TIS files).
  • There is some checksums that aren't currently corrected, EFILive needs to have some of these mapped for the V8 editor before that can happen (a no start will result).
  • You need to get an Auth-code for flashing (if you know the ECM Key you can create one), we cannot auto generate Auth-Codes for the E41 at the moment.


Again this is why we have not announced this as a feature as it isn't really ready to roll out yet, it all got put on hold and hidden in the software late last year to focus on the V3 development (and V8 editor).
