Depends on the ECU. Some can be made MAFless, some can not. To make MAFless sw you need to have MAP sensor installed on the engine. Even then it is not only one switch to turn of the MAF.
You can also upgrade the original MAF to bigger one.
There are only 2 products to make the universe work properly - Duct tape and WD40. If it moves and it shouldn't - Duct tape. If it doesn’t move and it should - WD40. Everything else is just stuff.
