The app

From the number to the finished file

Open the unit's read in CARTESIAN: the app names the unit from the file, then lists what it can do with it. Switch on what you need: the file is written with a correct checksum.

  • DPF, EGR, Lambda, speed limit, start/stop and more, one switch each
  • Fault codes by name, switched one by one
  • Automatic checksum, and IMMO OFF on supported control units
  • A modified file turned back into its original

Capabilities

Everything a workshop needs, in one editor

A focused desktop tool that reads the file, applies the solution and hands you a file that flashes straight.

Ready solutions

DPF, EGR, Lambda, DTC and speed-limiter solutions, applied per file and verified against the calibration.

Automatic checksum

Every file you save is checksum-corrected, so it flashes straight to the ECU. No extra tool, no manual step.
