The FIMAK allows for fuel adjustments at 200 different points on the power curve. Fuel settings are adjustable in 1% increments, with a (+/-) 20% limit. Fuel can be added or reduced at different throttle positions based on a riders riding style or preferences. Detailed adjustments can be made per every 500 RPM’s in the rev range. Also the block edit feature allows the user to select “blocks” of operating points and trim fuel. This feature is helpful when adjusting a wider range in throttle position or RPM’s. For tuning the bike while the engine is running use the “active” mode and all the adjustable fields are displayed on the blue backlit LCD display panel. *FIMAK can be used with more than one PIM unit. Great for use in a shop!
