Advanced signal interpretation: analyzes signal sources connected to the engine control unit (ECU), delivering visual results that clearly highlight mechanical issues and modernize fault analysis for users. Dynamic monitoring: continuously tracks engine RPM and changes in oxygen sensor data to provide accurate vehicle evaluation, with dynamic monitoring capabilities that enhance diagnostic precision and efficiency. Wide compatibility and integration: provides dependable system integration, handles complex setups, and supports varied communication protocols to be a versatile diagnostic tool across different vehicles and systems. Portable and durable design: reinforced cables for durability, a nonslip shell for secure grip, a compact body, and a lightweight form for easy toolbox storage. Use scenarios Quick prechecks: before service appointments, run ECUbased fault analysis to identify likely issues and visualize them, saving time on initial assessments. Onroad validation: during road tests, monitor RPM and oxygen sensor trends to verify repairs and confirm that the issue is resolved. Multivehicle diagnostics: in shops with diverse vehicle makes and models, easily integrate with different protocols to diagnose and compare across multiple systems without compatibility concerns.
