how does the pulse width work. Just looking at the canned tunes on my mini max. noticed the numbers are smaller on a cold engine and numbers get bigger on a warm engine. I figured a bigger number would be more fuel but it seems to be the other way around. Smaller pulse width flows more fuel?

What tables are you looking at? Pulse width is unchanged between temperature tables. And as pulse width increases so does fuel mass for any given fuel pressure

sorry yea im just learning the lingo and my way around the software. I was actually looking at the pre injection tables and thought it was a measurement of pw. trying to remove fuel at specifically low boost and throughout.
