Adaptive Tuner is a free utility application designed for Android devices, primarily aimed at users who require real-time monitoring of key engine parameters. The app displays critical gauge data such as RPM, MAP, MAT, WAT, and AFR, facilitating the tuning process for automotive enthusiasts. It also features a visual representation of six Adaptive Mode Learning State flags, eliminating the need for additional wiring, which can simplify setups using Adaptive Closed Loop for learning.

To use Adaptive Tuner, a compatible RS232 (DB9) to Bluetooth adapter is necessary, along with a connection to the Adaptronic’s second serial port. Users can connect via Bluetooth or through a wired USB connection for devices supporting host mode. As an open-source project under the Apache 2.0 License, Adaptive Tuner encourages contributions and improvements from its community, making it a collaborative tool for enhancing automotive performance monitoring.
