I know I don't need a conversion, it's more that I'd like to do it. Rather than explain what I'm trying to do, here's a picture (numbers are garbage):
This seems like a common formula.
VE = (3456 x CFM) / (CID x RPM)
Though it doesn't take into account air temp or baro pressure. There's enough info out there (like
this), it's just a matter of me finding the time to implement it.

You'll also need the .xml file additions in posts above, or I can send you my .xml (though it has been modified to how I think) and latest ROM including FlexFuel code.
You don't need any conversion - the table holds a mass flow value in g/s per RPM/MAP cell that gets input into the ECU instead of the MAF flow and the ECU does the conversion to g/rev - you can run full SD if you want, though there is quite a lot of variation at low load/RPM in the final SD value that I'm not sure would run smooth - probably anywhere above 40-60 g/s flow would run well.
If you do go MAFless, let us know how it goes.
