It allows you to run with or without a Mass Air Meter. Kind of like a piggyback fast for the stock ecm. Allows you to make changes if your good at tuning. I basically bought it as I had 2 MAF's go bad on me, so I decided to run meterless. Problem for me is I know nothing about tuning, so Im going to go translator and LS meter.
