3045 ICP

What do we know about the relationship of ICP and injector pulse width for a given MFD?

As ICP increases - PW decreases

Now, using the ICP map, pulse width map, and any given MFD, you can figure out what is happening when you replace that drop with a straight line.

PW never increases, instead just stays steady.


Bonus points for showing work......

Here ya go.......



Pretty sure I missed something though, too early for all this thinking.
