i found this online when i was looking for info on possible ways to fiddle with the intake sensors on EFI engines (lol just don’t ask…you really don’t want to know)

it would give one the ability to plumb the woodgas in below the the maf sensor and so stop the maf from being fouled by the soot etc that is carried in the woodgas
from the blurb thats written it gives you the ability to fool the ECU into thinking it is getting up to 50% more air than it really is…which would be pretty close to what would be needed for a correct woodgas fuel air ratio
