I hjave seen megasquiret fuel injection systems setup without air flow meters, however it would appear that to get the best out of the engine the ECU needs to know how much air is getting in rather than just butterfly position.

Why do you want to get rid of it?

If you unplug the MAF sensor then the ECU will try to runn limp-along.  If it has lambda sensors then it can keep running although it will be thirsty.
You can pipck up new MAF sensors for as little as £50 on flea bay.  Check the wiring in the plug first though ;)

Simplest thing would be to replace it - there is one on eBay (item 170304056528) finishing tonight that is currently 99p!
