Yes, I agree.I can't imagine running an EcoDiesel without some window into the soot levels. Otherwise there would be early regeneration terminations without even knowing it. When I get into the 70% range, I keep an eye out for an active regen to avoid premature shutdowns.
Honestly, this should be standard equipment.
I have both the Scangauge and the Tazer. They both connect to different places under the driver's knees. Think of the Scangauge as an instrument cluster on steriods that you use continuously. The Tazer is more of a set it and forget it device. There are detailed threads on here with options for mounting the Scangauge on the dashboard and fishing the wires.The ScanGauge II seems to be the most popular choice amongst 3.0 owners here. I was looking for something that incorporated additional monitoring along with some customization features of the Tazer or JScan (Tire size/TPMS/lights/etc.). It appears that both are necessary. Am I missing anything? Just pony up and get the ScanGauge for monitoring?
