Message: [QUOTE="Charles, post: 1360109, member: 103"] Tuning is tuning. Things get harder the faster the injector, that's about it. Conceptually, everything is always the same. When to spray, how hard to spray, how long to spray. There is NOTHING else going on with 7.3 diesel engine tuning... all the maps, parameters and functions in the world can never do anything other than those 3 things. That's why a small gear driven camshaft stroking plungers up and down works so well. The [i]actual[/i] goal at the end of the day ain't rocket science, although coaxing the computer into doing it sometimes can be... Most important thing is the order... Always, mass fuel desired, then injection control pressure, then pulsewidth, with each feeding into the next. Working out of order will send you in circles... I wish I could rewrite the function that relates boost to MFD so that it relates boost to PW... Would be SOOOOO easy to control fueling without neudering ICP! We [i]need[/i] ICP.... it's PW we can't have too much of at low boost! Anybody else view that is a serious bonehead coding screw up? [/QUOTE]
