So I got this letter in the mail via subaru saying they have developed a "modification to the Engine Control Module software logic to improve monitoring parameters within the OBDII system for the engine coolant thermostat". It's a free "update" but I'm wondering if it would jack up our reflash'd cars at all? I guess it isn't a big deal flashing back to stock, but it's kinda a pain in the ass for stage 2 folks. I should mention the top of the letter says it's only for states CA, CT, MA, MD, ME, NJ, NY, OR, PA, RI, VT and WA. So if you live in these states expect a letter from subaru I guess. Just wondering what everyone is planning to do.
