The Maptuner Nano Dealer Service Application is the next evolution of our professional diagnostic and service tool suite.
It’s designed for workshops and dealers that manage a large number of vehicles — now with full smartphone control through the MyMaptuner App.
No more PC, cables, or complex setup. Everything is handled wirelessly and on the go.

The features are:

Activation+
Multi-purpose testing and calibration of vehicle components such as injectors, fuel pumps, ignition coils, and iBR systems (for watercraft).
Each component can be activated individually for quick verification.

Reset Service
Displays service history, technician name, total running hours, and allows you to reset the service interval counter.

Reset History
Erase recorded ECU runtime data such as diagnostic logs and stored performance history.

Reset TPS
Calibrate the throttle position sensor by prompting the ECU to relearn minimum and maximum throttle values.

Read/Clear ECU Fault Codes
View both active and stored fault codes with extended diagnostic information.

Clear codes easily after repairs or testing.

DESS Key Management
Add, remove, enable, disable, or reactivate DESS keys at any time — directly from your smartphone.

Monitoring
Real-time viewing of vital vehicle parameters including Lambda/O₂ and other external sensors (requires HDMI/3.5 mm cable and compatible sensor).
