The flashing service eliminates the nuisance Diagnostic Trouble Codes (DTC's) that appear when doing a Subaru to Volkswagen engine swap (resolves many more DTC's than a hardware solution (For earlier years see: Code Killer). In order to have a functioning Check Engine Light it's helpful to only have serious trouble codes trigger an alert when something is actually wrong. You will be provided with the original and flashed backup files in case you ever need to replace your ECU in the future. 

For this service please follow:

1. Confirm that you have a 2002+ Turbo or 2005*-2007 Subaru 2.5L. If you have compatibility questions, please email busaru@busaru.com

2. Print and include this form with ECU: Project Info Sheet

3. Ship ECU to us (shipping address is on the Project Info Sheet above)

You only need to send your ECM/ECU/Computer to us and we can reprogram, or flash, the ECM to eliminate these trouble codes. Typical timeframe is 1-2 days.

*NOTE: Occasionally there are some ECU from 2005/2006/2007 that we're unable to flash (We have had issues reading PN's: 22611AJ561, 22611AJ550, 22611AK740, 22611AL211, 22611AM311).
