I did some city street driving this morning - about 12 miles back and forth. When I started this morning, Scangauge displayed 43% STM, and when I came back home, STM rose to about 48%. Regen count in the history of the Jeep was 3, and I had the last active regen some 800 miles back (approx.)
In the afternoon, I took my Jeep out again but this time on the freeway. Before I reached the freeway, Scanguage jumped up by 2% more to 50% (which is normal). After a few minutes on the freeway, I noticed that my Scanguage was showing regen on and STM was showing 79%. The active regen lasted about 8-10 minutes and when it turned off, STM was displaying 8-14% and the numbers were constantly moving in that range every few minutes. By the time I completed my commute, STM settled at around 12% when I shut off the engine.
So this was a surprising behavior (and I am actually pleased with this). Based on fellow posters observations that active regen begins when soot level hits 80%, I thought I had a long way to go before I see an active regen.
So here is my theory on active regens. It does initiate an active regen at 80% level, but it looks like it proactively does one after certain number of miles are driven without an active regen.
Hence, an active regen occurs either at 80% or 800 miles (approximation) - whichever happens sooner?
