Can you tell me what the EGT1 and EGT2 temperatures when you are towing the trailer with load on hills, mountain roads using the tuner. Hopefully the Tuner you use, provides that info. The Edge CS2 is what I'm using at this time. I monitor, (EGT1, EGT2 increases with throttle and grades), (EGT3, EGT4 involved with REGEN) and Rad temperature when using winter covers, which I use starting at 7 Celsius and colder season.
My concern, when I'm in the Canadian rockies, climbing long grades and using cruise control, towing 5k to 6k trailer/load, it will climb to 3000 to 3500 rpm and the EGT 1 and EGT2 would climb very quick to 1500 degrees F. I have my alarm set also, when it happen, I disable cruise control and drive the rest of the way with the peddle.
I feel, if one pushes at those temperatures too long, you will get a melt down and/or longevity of the engine drop drastically. FCA has refused to answer my questions or allow access to their engineers, the dealers ignore my request for info, so looking for input from owners of EcoDiesel 3.0
Something of interest I have noticed, the last two long trips 1000km or so, I only go through 1 REGEN cycle. I suspect, it the winter covers, it keeps the EGT3 and EGT4 in the 800 F range, and the Soot just creeps up very slowly. The first trip was just the winter covers, this trip I had the winter covers and used the Shell V-power diesel. Suppose to have Cetane booster, and many other additives. I'm still testing if it worth the extra cost.
