    Default Post injection? LOG

    Here is a log from a truck I am working on. It appears that post injection #2 is active. I thought it was supposed to be off? Has 45k miles, DPF delete section and AFE intake. The log starts with me idling through a school zone. The rest is cruising on the highway except at exactly frame #6000 and frame #12000 I stomp on it pretty good for a few seconds, about a 60-100 mph WOT pass. Thanks for looking! (I know I should have logged different PIDs)

    Yep, looks like factory settings. As I said in another post, setting injection events to 2 should turn it off, 3,4 and 5 will leave it on. If you play with it let me know, I'm interested. I'm not driving my truck much and this time of year is to cold for it. I'm thinking setting to off is leaving something on the table? From my logs, the quantity you are seeing is too much without the cat and such to heat up. I have b9301 looking like a knife on edge, with steep slopes on and off centered on 80mm3 peaking at 2600rpm with an 11 quantity. I heavily modified B1240 even though most of it will never be referenced. Until more testing or evidence of something, that version 4 of mine is where I settled. I still would like some more cells in that b9301 table...

    CwF, what you are saying makes very good sense. One of the issues with the truck is that it is too loud, also there is intermittent driveability / hesitation and the oil looks thrashed. I will set the injection events to 2 and log if it turns off. I also sent you a PM with more info. This truck is driven daily under a variety of conditions and I can log / flash it weekly. Thank you for your input!
