Engine timing cannot exceed the maximum timing reference. In order to advance timing, the main timing
map must be set below the maximum timing reference. I.E. If the crank trigger is at 40° and the main timing
map is set to 35° there will be up to 5° of advance available.
ENGINE TIMING
Using MSD View software, an entire timing curve can be mapped. The map specifies the actual engine
timing. The Power Grid will retard the input trigger to obtain the correct engine timing. The maximum timing
reference must be set properly for correct engine timing. These maps include changes in 50 rpm increments
and timing changes down to 0.1 degrees. A maximum of 30 points can be set per map.
This map will show all engine timing maps that are drawn based on rpm values such as timing curves per
gear. The information for all of these maps is accumulative in the software. In order to edit a particular timing
curve the user must go into the proper tab per function.
Start Retard: As part of the general engine timing curve, users can specify a start retard. While each engine
responds differently, the typical recommendation for a start retard is to to pull out 10° from 0 - 600
rpm. A variety of other ideas can be applied to a start retard, including ramping timing in as engine
rpm climbs. Use of such techniques is at the discretion of the user.
GEAR CURVES
This program provides the ability to modify the timing curve for each gear. One curve can be created for each
gear, up to six, from 0 – 15,000 rpm in 0.1° increments for every 50 rpm. You can program up to 30 different
points on each Gear Curve. The number of gears shown and how a shift is detected are dependent on the
selected values in the Settings tab.
In the Ignition Timing – Gear Curves tab, an individual curve is plotted for each gear. Each change made for the
gear curves references off of the Main Timing curve are set in the Engine RPM tab, not off of the max timing
reference. Gear curves are NOT cumulative; i.e. Retarding 1° in 2nd gear does not affect 3rd gear settings.
Note: The gear curves are independent of each other. In order to make progressive changes, one gear’s
starting point must match the final timing of the previous gear’s curve. Leaving a gear curve unedited
will result in normal timing for that gear regardless of other gear curves ahead of or behind it.
INDIVIDUAL CYLINDER TIMING
Note: To control ICT an inductive pickup, PN 7555, is required.
To accomplish timing changes per cylinder the engine’s firing order must be entered first. Firing order is
programmed in the tab Ignition Timing – Individual Cylinder – Firing Order by numbering the order into the
Value column. Many common firing orders can also be imported from a database within the software; to do
so simply go to FileImport and open the “firing_order” folder where an engine description can be selected.
Similarly, if an engine uses a firing order not included in these options the settings can be exported to be
saved in the same file.
After the correct firing order is entered individual cylinder timing can be created by editing rules. Up to 10
rules can be entered to control various aspects of timing for a single cylinder at a time. Each rule has six
(6) values that can be controlled; Cylinder, Retard/Advance, Timing, From Gear, Delay, and Ramp Time. To
make a rule the first four control values must be entered, Delay and Ramp Time may be left at the default of
0 if desired. When timing is changed on an individual cylinder, in order to bring the cylinder back to original
timing an equivalent amount of timing must be used to offset (DO NOT use 0°). I.E. If cylinder two is retarded
by 3° in RULE 1, in order to put the timing back in the cylinder must be advanced in a later rule by 3°.
Cylinder: Double click this value to select the cylinder for which timing is to be altered.
Retard / Advance: Enter whether timing will be Retarded or Advanced. After using this option timing changes
will always be entered as a positive number.
Note: Engine timing cannot exceed the maximum timing reference. In order to advance timing, the main
timing map must be set below the maximum timing reference. I.E. If the crank trigger is at 40° the main
timing map is set to 35° there will be up to 5° of advance available.
