Not really sure, I would need to compare SD based os for 6r80 how it differs from what I used as base. And probably it would be easier just to port my changes onto that OS.
What is use case where you would want to switch from MAF to SD ?
Im generally asking cause my twin turbo car with 6870 twins is doing just fine still on MAF and I just don't seem to feel where SD would be better/easier.
I have in mind adding nitrous support into LisevOS since I figured all I would need to do is simply add some airflow into MAF sensor function and it would increase needed fuel and increase airload which would handle spark related stuff easily

As far as use case. For max effort NA builds, the MAF restriction could be meaningful. I do want try an OTR which is apparently tricky for MAF to work well in that quick ram up into the TB. And I suspect transient fueling and feel may be improved with a MAP only calibration.

I've helped my friend build max effort 10r80 N/A ( 700 rwhp ) with 5" diameter OTR I've welded up from aliexpress pipes and bellmouth and only problem I had was getting idle to work properly in windy conditions ( wind was blowing through MAF sensor and bouncing back from closed throttle ), other than that it worked without any problems or differences from Steeda CAI, at least in drag racing/dyno environments.
And that idle condition can probably be tuned out since I found there is MAF smoothing time table based on engine rpm ( with value of 5ms for 1000 rpm and going up to 20ms for 6000 rpm ).
But in case if you wanted to switch to MAP settings, from hardware point of view, MAP is just analog sensor that takes 1 pin from ECU. IMRC1 and IMRC2 plugs have 5V, GND, and ecu PIN and as far as I know Roush OS just uses those pins. On gen2 those are Molex MX150 plugs and making harness would be simply making extension that you plug into IMRC and MAP sensor on other end.
On my car, I use IMRC1 / IMRC2 just to log Fuel pressure and MAP.
F-150 gen2 calibrations have separate MAP pin that is unused on Mustangs
