  • Modified UI to allow more configurable options
  • CSV header customization - you can now customize the order of the CSV header rows, and create your own custom formatted header row
  • STmin adjustment - allows manual adjustment of inter-frame delay. This is useful for some bad gateways that drop frames.

  • Variable selection now persists across inits, it is no longer cleared every time.


  • Added workaround for some Mercedes EDC17 controllers that do not support DDLI properly
  • Some Mercedes controllers have data arranged as large measuring blocks with many values in each block. Changed the ID's in such controllers to show block number. Choosing variables from the same block means higher logging speed.
  • Translation DB Updated


  • Mercedes UDS Basic ECU protocol now supports all UDS ECU's
  • Due to data source changes, some variable ID's changed in Mercedes Basic gasoline ECU definitions, one of them is knock retard. Please adjust your profiles (sorry!).
