Message: [QUOTE="Charles, post: 1329020, member: 103"] Driving to work this morning I feel pretty good that this is working the same as it seemed to yesterday. Last night I captured the values at around 150 or so degrees where the break over point seemed to be where points beyond started climbing again, and pasted those exact values all the way out to the 290 or so degrees the table stops at. This has totally cured the changes the truck (and every other truck I've worked with) from running worse fully up to temp than they do when they are midway warmed up. It also seems to have cured the issue of beating on the engine a little, then coming back to idle and having the truck run ragged. I'm starting to think that was all a function of the EOT rising after you run high power and pushing you into these moronic pulsewidth multiplier values, running your minimum pw too high. With the truck fully warmed up (driving for over 45 minutes) I nailed it full power (lifting for shifts obviously) up to around 90mph and when I came down to idle at a red light the truck was just sitting and purring like a 5.9. I have NEVER had that happen.... EVER. Could have been coincidence, but the truck is just driving so consistent right now after making this change day before yesterday. I think this may be more self-inflicted drama manufactured by a keyboard jockey. The injectors don't seem to [i]actually[/i] vary in operation. The only variance I'm seeing is the table purposefully put in place to change injector operation as the truck warms up. Lastly.... all diesel engines need starting fuel allowance for cold weather. Not just Heui injectors. My little Deutz I built on my irrigation pump has a little push button that slides the rack for additional starting fuel. Can't blame that on thick oil... [/QUOTE]
