JDMscan is a free Android app developed by Denis Kochan that uses the SSM2 protocol to obtain data from the control units of SUBARU cars through a K-line USB adapter. The app is designed to provide an easy way for SUBARU car owners to access and monitor their vehicle's performance and diagnostic parameters. It should be noted that the maximum polling speed of parameters (in "fast polling" mode) is achieved when using an adapter based on FT232, and errors may occur with other adapters.

The app provides a user-friendly interface that allows users to select and monitor various parameters of their car's engine and transmission systems. It also includes an extensive list of PID codes for the SSM2 protocol, which can be downloaded from the app's website. Overall, JDMscan is a useful app for SUBARU car owners who want to keep track of their vehicle's performance and diagnose any issues that may arise.
