MAP SWITCHING

The SMT8-FT comes with two entirely separate tune maps in memory. We call them map "A" and map "B". The LetRipp Software displays the present map in the upper  right hand corner or in the STATUS display. Two maps are used for :

 

  • Performance versus Economy
  • Tested versus untested
  • Normal versus high altitude
  • Good fuel versus bad fuel
  • Weather


Note : Please make sure that you have a valid tune map in map "B" before you flip the switch

 

SMT8-FT - Map Switching

The two tune maps can be invoked by :

 

MECHANICAL SWITCH

 

There is an option to connect (pin 8/12) an external mechanical switch to the  SMT8-FT to enable it to do map switching. Without this mechanical external switch, the unit will default on power up to Map A (open pin). Should the mechanical switch be installed, the unit will power up and tun on the map selected. The transition between maps switching is seamless and can be performed while the vehicle is in operation, provided both maps are loaded.
