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?

Wild would be LOTS of boost essentially, cams, ect. Enough to take the MAF out of it's operating range. It can only read so much air, and once you've exceeded that, it's a no brainer. The move to MAP usually happens when doing the final tuning and it becomes known that you're exceeding the capabilities of the MAF. Take my TT Corvette for instance. When the kit initially went on, we were planning on sticking with a MAF tune. But while tuning, we found that the MAF tables were just getting blown straight through, so we switched to a Speed Density (MAP) tune, and the car was rock solid after 3 straight days worth of work. With the new setup however, we're moving back to a MAF tube, but using a drop in maf out of a Saturn Sky Redline which has GREATLY extended frequency ranges that will hold up to the boost I'm going to be running.

If it's a MAP system, it doesn't hurt to keep it that way, and it doesn't hurt to add a MAF. Just depends on what your pain tolerance is, or rather where/when you want the pain. Tuning pain with MAP, redoing lots of wiring with adding a MAF.

The catch is finding a MAF that has the extended frequency range needed that can be wired up to work with the application.
