You need to setup this module after installation.Perform the setup only when the engine is WARM so the idle speed is normal,Find a long,straight road with light traffic.The unit does not learn the same gear twice,this makes it easy to set up on the road.You can even shift down and stop during the setup if needed.Do not stare at the display,watch the road and ride with extreme care as always! -Turn the ignition On.The display counts backwards(6 to 1)indicating that the memory is clear. -When ''L''is flashing,stare the engine in Neutral and let the engine idle. -The display will blink ''1''.Select first gear, release the clutch, and keep the RPM above idle speed. The display is blinking faster while the unit is learning the gear. -When the display shows ''2'', select second gear. -Repeat this process until all gears are thought (5 or 6). -The unit is programmed and should indicate the gears correctly. -Now, when ignition is turned on, the display counts forward (1 to 6) indicating that it is fully functional.
