Does plugging in a maf sensor into a mafless tuned ecu affect it in anyway?

my understanding is it ignores input from maf and reads another input

Why would u connect up ur maf sensor if the car has been tuned to run without it?

I suspect he has cluey law enforcement where he lives- and if he opens the bonnet and has no MAF sitting in there, he may get a defect/offense.

I've heard of people plugging the MAF back in to make it appear its working, to make things look factory under the bonnet, etc. Police in my area would not even know what a MAF is or does, but I've heard some other states and areas are more aware of it.
