## Description

TOYOBD1 is a specialized data logging application designed exclusively for Toyota OBD1 vehicles. It integrates seamlessly with the TOYOCOM and OBD1READ tools from zf-scantools, providing users with detailed real-time data visualization via customizable display cells or combined graph views. The app allows you to configure each cell's display mode with intuitive horizontal and vertical swipes, enhancing user experience.

Key features include a trip computer to track your journeys, an instant miles-per-gallon (MPG) calculator for fuel efficiency monitoring, and a thermal audio alarm to alert you if your engine overheats. TOYOBD1 captures and saves every data frame received, storing it locally on your device with options to export as CSV files for further analysis. Supported engines and full compatibility details can be reviewed at the official zf-scantools website.
