To: All Subaru Dealers From: Subaru of America, Inc. Date: August 13, 2008 Re: WVE-15 ECM Reprogramming Service Program 2008 Impreza WRX STI SOA has initiated a Service Program (WVE-15) to reprogram the Engine Control Module (ECM) on certain 2008MY Impreza WRX STI vehicles. Under certain harsh driving patterns, specifically when repeatedly or continuously operating the engine above the “red-line” (RPM above 6,700), abnormal combustion could occur resulting in serious internal engine damage in the form of broken piston ring lands. This abnormal combustion condition is the result of an “over lean” fuel mixture caused by a combination of fuel cut activation and high turbo boost. To prevent this condition from occurring, Subaru has developed a modification to the Engine Control Module software logic that will improve combustion management above “red-line” engine speed. This revised logic will not adversely affect peak vehicle performance. General information concerning this Service Program: • The WVE-15 Service Program Bulletin will be posted on the Techinfo.Subaru.com website on Thursday, August 14th. The Campaign Bulletin contains additional information concerning identification of affected vehicles, repair and claim submission procedures. • On or around August 14, 2008, dealers will be sent affected VIN lists by their Area Service Office. Dealers are requested to immediately perform this campaign on all affected vehicles in dealer inventory. Important: Some vehicles that appear on dealer affected VIN lists may have already been updated by Subaru. Prior to performing repairs, confirm coverage by using the Vehicle Coverage Inquiry in the Dealer Communication System (DCS). Vehicles that have been updated by Subaru will appear "completed" in DCS. • CDS control numbers for this Service Program are currently available through DCS. • Subaru will mail owner notification letters on or around August 15, 2008. Reprogramming software: The July 2008 SSMIII Software update was released by SOA on August 12, 2008 and contains the reprogramming pack file needed to complete this Service Program. Upgrade Version Numbers • Software: 1.15.33.3 • Interface Box: 1.6.0 • Interface Box CF Card: 1.2.35 Pack File 22611AN351.pak. - 2008MY Impreza STI, ECM To prevent the abnormal combustion during fuel cut and recovery condition by rev. limiter Thank you for your cooperation in this matter.

outstanding! they managed to GOATfuck the 08 ecu too! whoohoo! and people are excited about what comes next... why?
I'd like to know if this affects the Non STI wrx as well. I believe its the same block and injector configuration...though of course the ECU map would be drastically different. Still...broken ringland = :weaksauce So much for the "Thou shalt always seek the redline" ad campaign.:unamused:
