Free Diagnostic software for factory ECU.

The NDSI Lite app provides basic diagnostics for N i s s a n and I n f i n i t i cars. It is intended for older cars that have a grey 14-pin Consult I connector. Those are usually cars build between years 1989 and 2000. The connector is typically located near the fuse box. For a list of supported vehicles please visit our website.

This application supports both, petrol and diesel cars. It communicates with the engine ECU using Consult II protocol. It uses the same communication protocol as the dealer diagnostic tool. This protocol is far more comprehensive than the generic OBDII or ISO9141 protocol.

The video recorder function saves an mp4 video file with accompanying data log file. An Overlay software such as RaceRender can then be used to generate videos with custom data visualization. Video recording is disabled in Lite version.

A Bluetooth or USB diagnostic adapter is required to connect to the car. Those can be purchased from eBay, Internet stores or hobbyists.

Visit our website for a list of tested and recommended adapters.

USB adapters based on FTDI or CH340 chips are supported. Your Android device has to be capable of USB Host functionality. You will also need a USB OTG (On-The-Go) cable to connect the USB adapter to your device.
