What it tunes

What you need

No installer: unzip it anywhere, for example C:\EC-APPS\PerfektToolbox\, and run it.

Perfekt Toolbox writes settings straight into the car's modules. Back up a module before you change it. The program comes as is, without any warranty: whatever you change, you change at your own risk.

What's new

Version 0.3(current)

  • Instrument Cluster: new option “Use motor step data for testing” – the needle lands on the mark you asked for even on a non-linear dial, such as the M5 speedometer.
  • Changes not yet written to the module are marked with an asterisk on the “Write to ECU” button and in the tool tree.
  • Instrument Cluster: Test-drive is available only after the data has been read or written, so the needles are never tested against values the cluster does not have.
  • When a module rejects a value as out of range, the error message now says so.
