Mr.DirtyDangles Posted September 21, 2015 Share Posted September 21, 2015 Yeah, the mode that lowers NOx for testing only (the problem in question), apparently does so by running lower cylinder temps. Those lower temps create less NOx but they also create less power, lower fuel efficiency and create more soot. The additional soot of the 'cleaner' test mode will shorten the lives of components. The test mode creates less power, less efficiency and shortens life span of components. The until now 'regular mode' creates more power, better efficiency and less soot but evidently too much NOx.
