TOYOBD1 is a free datalogging application designed for Toyota OBD1 cars. It works perfectly with TOYOCOM and OBD1READ tools from zf-scantools. The app displays data in separate cells or all together in a graph. It allows you to configure each cell display mode by horizontal and vertical swiping.

TOYOBD1 features a trip computer, thermal audio alarm in case your engine overheats, and an instant MPG calculator. You can see all the data received from the car through the OBD1 protocol and possibly more. The app allows you to save every frame received in a database on the phone and export it to a CSV file as needed.
