MAF is a challenge with the 8 stack. You either have to use 8 MAFs (one for each stack) or you could try one MAF on one stack. I think the Megasquirt will certainly let you do one MAF on each side of the engine (total of two). I doubt it will support 8 MAF, but maybe so.

Or you could build a removable plenum to seal up to the 8 stacks and have one opening to pull air through and put a single MAF there. If so might as well pipe it to a cool air source while your at it.
