With the WOLF3D or any other system including mine, you cannot read the humidity and barometric pressure with a MAP sensor. This is why I like the MAF meter.
I know a few BMW guys who spend alot of time doing club days at tracks. They removed the stock airflow meter and go to a Alfa-N system.[they replace the meter with a MAP sensor] They dyno and make good power, the stock meter is small. If the track is at near sea level the car runs good. However the car runs rich above sea level and when they go to Watkins Glen and hit the higher ground the car runs like crap. Why does this happen? The tuner that dyno tunes the system is near sea level.
If you like the system you now have and do not mind tuning for weather and other chages a lot of times that is great. I am tring to point out that the main thing that people did not like about the MAF meter is that they were small. That is no longer the problem.
Back to the future, why has most of the OEM companies gone from MAP to MAF?
Thanks again
