Connecting an OBD2 interface to ISTA software can be frustrating, often leading to the dreaded “interface not found” error. This guide provides a free solution for establishing a successful connection using a readily available ISTA version and a standard OBD2 cable.
This solution utilizes the “ISTA_v4.29.30 – Sedoy Standalone” version, which offers an automated installation process. While the installation may take a couple of hours, the simplified setup eliminates much of the complexity associated with other ISTA versions. The downloaded package includes a loader, ensuring all necessary components are extracted and installed correctly.
After installation, a few critical configuration steps are required. First, change the port settings to COM1 in both the Device Manager and the ediabas.ini file. Access the ediabas.ini file with Notepad and modify the line “REMOTE” to read “STD/OBD”.
Next, locate the obd.ini file. If it’s missing from the same directory as ediabas.ini, add it. Open obd.ini in Notepad and verify that it also designates “COM1” as the communication port. Create a desktop shortcut for the instagui.exe file for easy access. Launching ISTA via this shortcut should establish communication with your Bimmergeeks cable.
This entire setup can be installed on an external hard drive, enabling use across multiple laptops. Remember to adjust COM port settings accordingly on each machine. While this guide focuses on a Bimmergeeks cable, this process may also work with other compatible OBD2 interfaces.
Finally, although this setup is currently working with a standard OBD2 cable, an ICOM cable is recommended for optimal performance and functionality with ISTA. Configuring the ICOM cable will be the next step in enhancing the diagnostic capabilities of this setup.
