If you're going to get it dyno tuned, no big deal. But if you aren't, then you could do what I did... setup the MS for a MAP sensor, but go ahead and wire in the MAF. Then street tune it (with the MAP). After it's tuned, drive around and take logs with both sensors attached. It'll log MAP and MAF. You can then plot the data in excel (MAP vs MAF vs RPM), and deduce the proper fuel and spark tables. It'll give you a good starting point for fuel, and the spark tables will be dead on.
sorry for resurecting the dead.
Justin you said you tuned with both sensors in to plot the data. I presume this is because at the time you didn't have a airflow to voltage table for the maf\afm?

That's right, to my knowledge no one had run a megasquirted miata with the AFM before, so I had no VE Table to start with. However, that was MS-I. It wouldn't be nearly as easy for MS-II since it doesn't use VE Tables for MAF mode.

There is no need to do this if you just plan on using a MAP sensor.
