Adjusting this mode will have the same effect as changing the Main jet in a carburetor. Mode #3 (FLASHING RED) changes your air : fuel mixture at high & wide-open throttle positions & high RPM ranges. Adjusting this mode will have the same effect as changing the Needle position in a carburetor. Mode #2 (FLASHING YELLOW) changes your air : fuel mixture at mid throttle positions and mid RPM ranges. Adjusting this mode will have the same effect as changing the Pilot jet in a carburetor. Mode #1 (FLASHING GREEN) changes your air : fuel mixture at low throttle positions and low RPM ranges. Before adjusting, you must determine what aspect of the jetting you want to change. Mode #1, 2, & 3 allow you richen or lean out the air : fuel mixture, just as you would re-jet a carburetor. There are five (5) modes which you can adjust. The LED's positions increase and decrease proportional to the throttle position. 'Monitor' mode is used during normal operation. It is now in the 'monitor' mode and the LED should be green.

Immediately after start-up the LED's will initially cycle and end up at position #1. To access these modes, you must have the power on with the engine running/idling. There are also eight (8) LED's on the face of the module which display values/settings for the different modes. The three buttons are labeled with 'Mode', '+', & '-'. The user interface is made very easy with the three buttons located on the front of the module. Please read the following instructions for adjusting the FI module. Understand that without the proper knowledge and equipment, any changes can result in decreased performance and/or reliability. However you can make adjustments to the module for the purpose of 'fine-tuning' since all units vary slightly. If you acquired this FI module as part of an Alba exhaust kit which you purchased from us, then we have pre-set the module with settings we determined through rigorous development and testing. This module is adjustable and allows us to 're-map' the fuel curve to accommodate for any changes made to the ATV. Therefore if you use a good performing exhaust (like ours) without a fuel management module, your engine will run 'lean'.

It only compensates for changes in atmospheric pressure (elevation) and temperature. This means that the fuel injection system does not re-calibrate itself for use of a performance exhaust system, or for any other motor modification. NOTE: The fuel injection system on your ATV/UTV is known as an 'open-loop fuel injection system'. Please read the following instructions/information prior to using the module. 'Thank you for purchasing an Alba Fuel-Injection control module.
