Stopped by my dealer yesterday to inquire about the surging - I've got an early '05 with about 14,000 miles. They told me they checked with Subaru and the ECM reflash does not apply to my car as the VIN is not within the range. They also stated that my car has the most recent ECM logic (assuming it's because I don't fall within VIN range). IS there are a VIN range for this fix or does it apply to all 49-state + CA/NY emissions-equipped 5MT LGTs?
Mine may not be afflicted as bad as some of yours (or I've just grown accustomed to driving around the behavior), but just wanted to let you all know what I heard. I only use 93 octane gas, but we don't have any 'Top Tier' gas retailers in the area. I'll probably AP and UP/DP the car at the end of the warranty period anyway, so I'd like to thank SoA for writing crappy ECM code that helps justify my purchase of speed mods.
By the way, the tech that drove my car 'could not reproduce the problem', even though I told the service desk it primarily occurs from cold start and you don't drive it like you stole it.
