Data/Spec. Sheets

[Todd Knighton]

Tom,
	Motorola has a lot of data sheets on their MPX4250A, etc. line of
pressure transducers we've been using.
	National Semiconductor will send you free LM1949N's for injector
drivers.  Cherry Semiconductor is more proud of theirs, but will send
you all the data sheets you want.  I understand that GM and Ford both
used these drivers on their throttle body injection stuff.
	The MAF's are a tough one.
	There used to be a book, called the "Bosch Bible" by most, been looking
for it too.  It used to give specs on all their stuff.  Now the only way
you can get parts is to know the car it came off of.
	If any one knows where to get this Bosch spec book let me know.
	Throttle position sensors are pretty self explanatory.
	Temp sensors typically all follow the same curves, pull a curve out of
an oem to linearize it, then convert directly to deg C or F or whatever
your fancy.
