Changing 165 fuel delivery

[Mike Rolica]

Yes.. I think so.. loking at using a ford maf... but you loose resolution on
the idle side...what really needs to be done is a larger range aquired....
This is limited in the ecm... that is where the 16 bit comes in.... still
trying to figure out how to make it a 16 bit valuye..
Get increased tresolution.

		Can the MAF be made to work with hi-po engines (by switching
the MAF or
		programming), or am I going to have to switch to MAP when my
Corvette is
		done?
