Can I use the MAFT to simply measure airflow?
Ok, I agree that using the MAFTpro to simply log the amount of air going into my engine is overkill, but ...
- can it be done? I'm guessing yes
- and what components would I need to do it? (MAFTpro - or maybe just a plain MAFT , air temp, MAP sensor ... ?)

Because knowing how much / how well my engine is flowing air will allow me to make more informed decisions when choosing cams/turbo/intake manifold. Let's just say that I am not quite happy with my power curve right now, even though it has been shown to be flatter than similar setups (AMS 3071).

You could use the Pro to datalog the car, even if you are not controlling the engine with it.
You could log:
Boost
Throttle
RPM
Wideband AF ratio
EGT
Manifold Air Temperature
Airflow

I would love to sell you a MAFTPro, but honestly, it is a big waste of application for such a feature filled unit, just to use it to look at data that you can obtain for cheaper.

I already run a XEDE and I do not want to hook up any other device to the stock MAF. So unless I can hook up an SAFC using a separate MAP sensor, I don't think it'll be an option. Also, doesn't an SAFC-II run about $300? At that point I'd rather get the MAFTpro...
Right now I'm in the process of looking at different potential solutions (one of them being the MAFTpro and another being the auterra scantool). To get an idea of how much a MAFTpro setup would cost, which components would I need to get in order to measure airflow?

I have a feeling you think the MAFTPro is some kind of diagnostic tool, which it is not. It is an advanced fuel, boost controller with map switching and allows you to REMOVE the maf altogether. It would REPLACE the XEDE, not be used to measure something.
You could log:
Boost
Throttle
RPM
Wideband AF ratio
EGT
Manifold Air Temperature
Airflow
Boost
Throttle
RPM
Wideband AF ratio
EGT
Manifold Air Temperature
Airflow

I thought that the MAFTpro can also run using a MAP sensor, no? So couldn't I run a MAP sensor separately_from / in_addition_to the MAF? That way I don't have to mess with my current setup and I run the MAFTpro only to log, not to manage.
MAF Hz doesn't really tell me the volume of air flowing ... to calculate the volume, I also need air temperature and barometric pressure, which is something the XEDE does not log. Maybe the auterra software can log the values from the ECU, but I have not found anything to confirm that (esp. not on an Evo).

why not just use an ODBII datalogger like this one: http://www.auterraweb.com/
I have it. It reads air flow in lbs/min. It also logs many other things including timing, air temp, rpms, throttle poss., speed, fuel trim, reads fault codes and resets them and has a neat (semi-accurate) dyno, 0-60, 1/4 mile and more.

The scantools won't log Boost or EGT.
Even just configured as a logging device, the pro could be used to control boost.
But, there are many ways to skin a cat.... (so to speak.....)
