• TIP:For EFiLive", 06-09 trucks have five tunes. Later trucks have four tunes except2010-2012“cab and chassis" models which have two tunes, 2013+ is CSP4. lf the switch only selects two or four tunes, then you likely have a CSP2 or CSP4 tune
• TIP:For MM3, Smarty and RME, all tunable years have five tunes. Plug in the switch. It will start by blinking the firmware version number, a series of long and short blinks. Turn the key on and change the tune and it will blink the tune it just set. Test all the positions, if it correctly blinks the tune number in each position, than it's working perfectly. If it doesn't work in position five or in positions 3-5, you most likely only have two or four tunes and should follow the directions for moving the tabbed washer
• SIMPLE INSTALLATION: 5-Position Switch installation is simple. Unless you have a mounting bracket, installing the switch requires the drilling of two holes, one small and one large
