ADVANCE
This tab allows users to set change the prescribed ignition timing for the engine. The table allows
changes to be made in single degree increments based on engine RPM per MAP PSIA. Using the
table a tuner can adjust the timing anywhere from 30° of retard up to 30° of advance. See “Table
Features” below to learn about using and editing data tables in MSD View.
FUEL
The Fuel table in MSD View can add or subtract a percentage of the fuel injection signal based on
engine RPM per Throttle Position. All values entered to the table act as a percentage change to the
original signal from the ECU. The values in this table can range from -50% to 80%. At the lowest value,
fuel will be cut in half. The highest enterable value will nearly double the amount of fuel injected in
the engine. See “Table Features” below to learn about using and editing data tables in MSD View.
FUEL ACCEL
The Fuel Accel plot offers users the ability to recreate the functions of a carburetor’s accelerator pump
(pump squirt) in a fuel injection system. This feature monitors the signal sent to the fuel injector for
changes. Each time the signal increases an extra percentage is added to the prescribed amount to
assist the engine in acceleration. The extra percentage, prescribed by the RPM based line in MSD
View, lasts only during the time where fuel requirements are rising.
To plot a line, click and hold a dot to drag it to a new location. New dots can be added by right clicking
within the plot, or by entering coordinates in the table. The table shows the exact position of each
dot and can be found in the lower left corner of the MSD View window. The Fuel Accel plot includes
changes in 50 rpm increments and fuel additions of 1% at a time. A maximum of 4 points can be set.
The line designates a percentage of fuel to be added to the fuel system that is originally prescribed by
the stock ECU. The highest possible plot, 200%, will add two times the originally designated amount
of fuel. With the addition, three times the original amount of fuel will be injected during the specified
conditions under the 200% setting.
NOTES
The Notes tab allows users to keep basic information with a particular tune. The notes section works
the same way as a simple Notepad program. This area offers the ability to name tunes, explain
reasoning for changes, keep notes on the location or conditions when a tune was used or any other
plain text items the user would like to enter.
MONITORS AND GAUGES
The pane on the right side of the MSD View window allows users to see a variety of engine parameters
in real time. The top of the pane shows selected items in either list or gauge form. The bottom of the
pane lists all available items to be checked for monitoring. When the engine is running, users can
watch changes occur as they are entered into the software.
TABLE FEATURES
To edit the data in the table users can select a single cell at a time or select a group of cells to all be
changed to the same value. A zero in any given cell indicates the MSD unit is making no change to the
OE ECU’s output. To change timing or fuel data in a table the sign (+/-) of the new number designates
what type of change occurs. Use a negative dash (-) immediately before a number to retard timing
or decrease fuel supply. No positive sign (+) is required when entering a number to advance timing
or increase fuel supply. When a cell or group of cells is highlighted, use the keyboard to enter the
desired number. When a new value is being entered, the Up and Down keyboard arrows will change
the entered value by one value, respectively. To finish a change, click in a new cell or press enter.
