operation
The MSD FI Enhancer is preprogrammed with four base fuel curves. The curves are selected using the
switch labeled BASE. These curves adjust fuel delivery based on throttle position and rpm, providing
the right amount of fuel under all conditions. The four fuel curves correspond to varying levels of
performance modifications. These levels of modification are broken down into the following groups:
Curve 1 - Stock exhaust or slip on, stock or aftermarket air filter.
Curve 2 - Full exhaust and stock or aftermarket air filters.
Curve 3 - Exhaust systems and aftermarket air box.
Curve 4 - The fourth curve has all of the fuel adjustment values zeroed out. This curve is selected by
moving the rotary switch to any position other than Base 1, Base 2 or Base 3. This curve is
useful for those wanting to just modify the fuel delivery with the potentiometer adjustment,
without having any other adjustments.
NOTE: Any position other than 1, 2 or 3 represents Curve 4.
In addition to the four curves, there are three potentiometers that allow you to fine tune the curve you
select. These potentiometers allow you to adjust the fuel curve from +20% to -20% in three different
rpm ranges. The rpm ranges are:
Low - Idle - 3,000 rpm
Mid - 3,000 - 6,000 rpm
High - 6,000 - 9,000 rpm
To add fuel, turn the potentiometer clockwise. To subtract fuel, turn the potentiometer counterclockwise.
With the potentiometer pointed straight up at the thick indicator mark (towards the MSD logo), that
is 0% adjustment. Fully CCW is -20%, and fully CW is +20%. Adjusting the potentiometer between
these points will result in adding or subtracting an amount of fuel proportional to how far the knob
was moved from zero.
LED
The FI Enhancer has an LED that will illuminate when there is power to the unit.
