WinOLS JSON output for licensed WinOLS users

Source map values are not copied into the customer export

Optional DPF, EGR, AdBlue/SCR and DTC removal maps are offered only when supported

Where this fits

Workflow role

Upload the ECU binary, let WEREMAP match the closest supported profile, then create the WinOLS JSON. The base mappack contains matched tuning map definitions. DPF, EGR, AdBlue/SCR and DTC removal maps are optional add-ons and are offered only when the map set is safe for the uploaded software.

Best fit

Professional tuners who want a fast WinOLS mappack starting point for supported ECU software instead of manually transferring every map definition.

Before you use it

  • Upload the original ECU binary whenever possible.
  • Check the match score and optional map availability before creating the JSON.
  • Use manual file service when you need a complete mappack for a weak or unsupported software version.
