9098 Posted January 12, 2010 Share Posted January 12, 2010 I got the following message from Subaru to reprogram the ecm. It claimed that performance would not be affected. However the low end torque seems lower now ('05 Legacy 2.5i). Anyone else notice this?...... During a quality review, we discovered that under certain unique driving patterns, such as repeated acceleration and deceleration and/or continuous uphill driving at higher speeds (about 75 mph), your vehicle's catalytic converters may develop high internal temperatures that exceed design parameters. If left uncorrected, this condition may eventually degrade the efficiency of the catalytic converters. (The Check Engine light will illuminate to alert you if the catalytic converter efficiency has degraded beyond an acceptable level and if your vehicle may be releasing air pollutants that exceed Federal emission standards.) To prevent this condition, Subaru has developed a modification to the Engine Control Module software logic that will improve management of temperatures within the catalytic converters. This software change will not adversely affect the performance of your vehicle. Quote Link to comment Share on other sites More sharing options...
brus brother Posted January 12, 2010 Share Posted January 12, 2010 http://www.ultimatesubaru.org/forum/showthread.php?t=100679 Looks like the same notice I got about 6 months ago. Has the mailman been holding out on you or is this a different notification? Quote Link to comment Share on other sites More sharing options...
9098 Posted January 12, 2010 Author Share Posted January 12, 2010 It was on the subaru website when I entered my vin number. Quote Link to comment Share on other sites More sharing options...
brus brother Posted January 12, 2010 Share Posted January 12, 2010 Best part is if you do the reprogram, SOA extends the warranty on the cat to 100,000 miles:banana: Quote Link to comment Share on other sites More sharing options...
