The last emissions related purchase for this truck

[fargonaz]

Early Feb is when I did the tune up 02/04/17. Replaced all the sensors and cleaned the duct.

Has always taken about 15 minutes from an operating temp engine, 8-10 if it has already started dosing when I force it, goes to ~1000, DOC goes from 650 - 695. Since it started acting up the temp differential between inlet and outlet has gone from from 20 deg. diff to 80-100 deg. It usually tops at out ~1200 outlet and 1190 inlet.

I've save every session with the recording option(forced regen mostly) since I've been using the ecm adapter(Jan. or Dec.) They don't all have the same data points but all have the inlet and outlet and DPF differential.

I don't have a screen shot just some .csv files that it won't let me upload.
