Digital Mass Air Modifier -- 2008-2015 GM Vehicles (LCB, LMF, LU3, L20, L96)
The JMS Mass Air Modifier has been designed to accurately Scale and Filter a MAF signal. All adjustments can be made live “on the fly”. Once configured the MAF signal is shifted and filtered whenever the unit is “ON”. The Mass Air Modifier is “ON” whenever the ignition key is in the “ON” position (Green Power LED is ON). Configuration is simple, there is no need for a laptop, all you need is the enclosed screwdriver.
