Changing 165 fuel delivery was "General tuning question - fue l economy"

[Mike Rolica]

If your injector constant matches trhe actual flow rate of the injectors
then your blm showd be close to 128 until the maf maxes out then they will
get larger and larger and larger......boooom!

		Hmm, now I'm confused.  I would think telling the engine you
have bigger
		injectors would tell it to fire them less, delivering less
fuel.  The
		decrease in the BLM then means that the engine saw it was
rich and decided
		to pull fuel out.  I must understand how the ECM interprets
the injector
		constant and how it judges what to do with the pulse width.
(Trying to take
		a logical route.)  Keep in mind I haven't tried anything
YET, I'm just
		trying to learn.

		I *lowered* the injector constant (which means bigger
injectors) in the aujp
		by 20% and got a 20%
		reduction in most BLM cells.  It prolly works the same way
in a 165.
