MAF vs MAP Options

[jason]

Just curious what everyone's opinions on these are (FI application)

for a street driven car (low throttle driving) that also see's its share pf peppy driving (wot pulls) which is "better" and why?

blow off would be recirculated, and leaks not being considered, why would one choose a map system besides tunning capabilities?

IMO basicly, the MAF is fine, 1st provided it is in good working order (these 3sgte AFM's are getting OLD...) and 2nd provided you stay within its working range. IE: in the case of a 3s, once you get out of its range, you get what pitt got.
once you hit that threshold, your pretty much done.
with the map, you dont really have that "threshold" only the limit of what the map will read. (which in most aftermarket cases never gets seen with a 3 or 5 bar map that some of the guys are using.)
as long as your staying within the factory "margin of adjustment" with a MAF, IMO there is no downside to it, untill you go out of that range.

Manny pretty much nailed it.

Now this is also a good example of how knowing what car we are talking about, makes a huge difference. In the case of the 2nd gen, ditch that afm as soon as possible. It is responsible for all of the known 3sgte hesitation issues, inconsistent fueling and other problems.
