RE: MAF BLM based tuning

[Mike Rolica <mrolica@meridian-mag.com>]

	Bruce ,
	    With that being the case why would I want to trash the MAF in
favor of
	MAP for my future forced induction application?  I know that
upgrading from
	a '870 to a '165 would increase my serial data rate but what would I
gain
	from a '730? 
	Drive ablity, tuning is easier..i found droped me over .5 sec in ¼
compared to stock maf

	 Couldn't the MAF data be recalibrated with a prom to measure

	greater airflow than it was intended to measure stock? 

	Then you loose resolution and hencedriveablity 

	 I'm hoping for
	500-550hp and would like use the MAF computer in the short term.

	Been through all this when I was a newbie too.....the 730 seems to
be a newer ecm.. got more tables and options to play with, like lean cruise
mode, better tcc control(not that it matters to you)
	Easy to patch stuff from other 730 apps, close relative to 749.. I
think, so is possible to controll boost,ect ect..
	Trust me.. much easier to tune....better throttle response, and mpg
in town and in hills... higway was same as 165.,
