TS: IF BIU, DASH, OR ECU REPLACED – NEED VIRGIN FILES THEN SYNC WITH KEYS. Frequently Asked Questions What does Subaru BIU virginize mean? Virginizing the Subaru BIU erases the paired IMMO data so the body integrated unit can be re-synced with a fresh ECU, cluster, and new keys as a matched set. When do I need to virginize the Subaru BIU? When you replace a used Subaru BIU, ECU, or instrument cluster with mismatched IMMO data, virginizing lets you resync all modules together. Does this service cover 2000-2017 Subaru models? Yes. Our BIU virginize and IMMO sync covers 2000-2017 Legacy, Outback, Forester, Impreza, WRX, STI, and Tribeca equipped with BIU IMMO. Do I need to send the ECU and cluster together? For a full IMMO sync we recommend shipping the BIU, ECU, and instrument cluster together so all three are virginized and re-synced as a set. Will I need new keys after BIU virginize? Yes. After virginizing the BIU, new or re-learned keys must be programmed to the fresh IMMO set. We include key data preparation with the service.
