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?

Actually your typical MAF based system is easier to tune than a MAP based system because the fueling for the MAF system is all based off of airflow charts. X airflow = X fuel whereas the MAP system uses volumetric efficiency based on MAP, RPM, and Temp. The MAP system takes longer to get dialed in, adapts somewhat to temp/altitude changes but has it's limitations. It's biggest advantage is that the Fueling is MAP based, and you can extend the tables as far as you need. A MAF only operates in a certain feedback frequency range, so you're limited with how much boost you can run. Once you're out of the MAF frequency range you're essentially in a big guessing game and your tune pretty much ends up out to lunch.

For a mild setup, the MAF setup won't hurt anything. For a wild setup, I'd strongly suggest a switch to a MAP system.
