It should be .75-80%+ which you’ve surpassed. One more thing to note during the regen, does the efficiency ride below that threshold for a while and then it reaches .75-.80+? I’m trying to figure out if the problem is occurring during low or high temps. Sent from my iPhone using Tapatalktest cycles, they have poor NOx conversion efficiency when exhaust gas temperatures are low, such as during cold start, low-speed, low-load driving and during extended idling. This is because SCR performance is limited by urea decomposition issues at exhaust gas temperatures below 180°C. If urea is injected at exhaust gas temperaturesWinnebago Owners Club.
