eFlexApp can monitor your eFlexPlus device in real time. Choose from between three separate driving modes (Economy, Dynamic, Sport) and monitor the ethanol content, engine RPM, fuel temperature, engine temperature, injector duty cycle, injector activity and cold enrichment.

Adjust the RPM based enrichment with the driving mode selection (save the custom driving mode setting created with eFlexTuner software) and cold enrichment (save the custom setting created with eFlexTuner software)

Available via APP Store and Google Play.



Use eFlexTuner to adjust the RPM based enrichment and cold start enrichment. Save your custom settings to eFlexApp.
