Adaptor For BMW EWS IC, On-Board Reading, XPROG-M AK90 R270 Compatible With Diagnostic Tools

Introducing the BMW EWS IC Adaptor for XPROG-M AK90 R270, On Board Reading—a compact, plug-in solution by YIQIXIN that streamlines BMW EWS immobilizer work. Designed for professionals and enthusiasts alike, this adaptor lets you read and write EWS data using popular programmers such as R280 Plus, XPROG-M, AK90, and R270 with minimal setup.

On-board reading means no soldering required. Simply fit the adaptor on the EWS circuit and use the included cables and small circuit board to capture the data dumps you need. It supports BMW EWS 4.3 & 4.4 (9S12(2L86D) on board reading adaptor), giving you reliable access to immobilizer information for backups, diagnostics, and repairs. For AK90 users, select “2L86D” in the AK90 software; with XPROG-M, the small circuit is not required during reading; for R270, ensure you use the longer cable for proper connection during reading. The package includes all components needed to fit a variety of workflows, right out of the box.

Keep in mind the preparation step noted in the documentation: before reading, use sand paper to scrape glue off the circuit on the back of the EWS to ensure clean contact and stable readings. This small step helps prevent contact issues and improves data integrity during the reading process.
