Perfekt Toolbox

What it tunes

Instrument Cluster (KOMBI)
Nearly every instrument cluster except the E65/E66 and the X3 E83: module info, backup and restore, needle test.
- Speedometer
- Cruise control
- Fuel tank
- Tachometer
- Warning zone
- Consumption/oil temp
Body Gateway Module (KGM)
Hidden settings for the E60–E64: mirror folding and unfolding speeds, right mirror tilt in reverse, dimming voltage for FLA_R.

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

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.
