Nissan Specific Features:
Fast ECU Flashing: Allows ECU map change flashing time to be reduced to 40 seconds or less!
Map Switching: Switch to another map on-the-fly while you drive for optimal tuning for every situation.
Map Slot Throttle Tables: Each map slot now has unique throttle profiles, increasing the level of customization for each map slot.
TPMS Learning: Easily re-program TPMS sensors for new wheels and tires using the Accessport and prevent cumbersome trips to the dealership!* (*requires common Tire Pressure Positioning Sensor Tool)
Speed Density Tuning: Tune using the MAP sensor instead of the MAF sensor for big-power builds that exceed the stock MAF sensor's maximum capacity.
Realtime Tuning: Changes can be made to the map in realtime, while the engine is running. Greatly speeds up the tuning process and allows quick changes to powerful features like Lauch Control, Flat Foot Shift, and map switching.
