Message: [QUOTE="Charles, post: 1328951, member: 103"] On the advice of nearly everyone, I took a long hard look at the "Fuel Pulsewidth Multiplier" and found that it was not stock, as well as one other thing unrelated to cold-weather cranking. After putting this table to stock, the truck smokes easily half what it did, if not less right off the bat, and stops smoking entirely in most situations I've noticed after running a while. The sound out the tailpipe is totally different as well. I would like to put the truck on the scope and see what is ACTUALLY being changed, aside from pulsewidth, and to what degree. This same table seems to also have held the key to how the truck idled and felt after up to temp. A strange thing I noticed was that in this same table, as the engine approached operating temperature the values that up to this point had been dropping toward 1.00, start to rise again, to notably higher values down near idle rpm. From what I saw today..... cutting these values off once they hit 1.00 near operating oil temp had a dramatic effect on making the "injectors" run the same once up to temp as they did cold. I think I may have found the reason trucks want to start running ragged suddenly as they come up on temp. They get tossed too much pw because of a multiplier, specifically as they climb past 150 or so degrees F. I'll keep noting how the truck runs daily, as it may change once we have some warmer weather again, but today the truck was perfectly the same from a cold start, all the way up to operating temp in terms of idle. The only thing I changed tonight was to keep the stock values (above 1.0) at ICP values above idle, as the truck actually [i]lost[/i] power once up to temp today as the multiplier settled down to 1.0. Pedal went flat and the truck took a lot of right foot for the same result. Near as I can tell, the table works much, much better stock, but..... the injectors aren't ACTUALLY varying in their operating nearly as much as that table is compensating. The injectors are damn near constant in output from operating temp down to pretty low temps. It doesn't seem to be until the oil starts looking like a breakfast syrup that they seem to need a little help. If this file pans out I'll upload an updated version for AEB. [/QUOTE]
