MAP/MAF Blend on MS-II

I was wondering if anybody out there is running, or had experience running a MAP/MAF blend system on their MS-II for their Z? I am getting ready to order my MS-II but I want all the details worked out before I buy something I won't be able to use for what I want. My current engine build will be a 78' L28 block with N47, ported/polished and modified chamber, head running flattop pistons for around 10.5:1 compression, 6 into 1 exhaust header with free flow system all the way through, and custom fab'd intake with 65mm TB, WB O2, and knock sensor with spark retard functionality. I am thinking of using a MAF sensor out of a Ford V8 mustang. there are two reasons for this; first is because is should be able to handle the flow without as much restriction for our inline 6's, second because there is plenty of information on the MS page regarding calibration curves that somebody else has already figured out for these sensors. I am really trying to make this work because the ease of tuning and for absolute accuracy across the board as far as knowing how much air is entering the engine at any given point so I don't have to make an educated guess as to what my VE is. I plan to use the normal MAP/TPS method for lower RPM because the MAF sensor is made for larger airflow and probably won't be accurate on my engine below 2k RPM. I need to know if I need to use the microsqurit code to do this, and if I do what are the tradeoff's I’m taking to do so. If anybody has any warnings or advice on this would be helpful seeing as how I’m not so sure how well this setup works on MS-II.
