PROGRAMMABLE FEATURES AND SETTINGS:
GENERAL
These are the most basic settings of the system. They will need to be set the first time the system is installed
in a vehicle.
Number of Cylinders: This tells the system the number of cylinders. Must be selected correctly for proper
timing and rev limiting.
Maximum Timing Reference: This is the advance that is set with a locked distributor or crank trigger. The
system controller will use this as its base for all timing marks and can never advance past the pre-
set point. It is critical that this advance is set properly.
Note: When using EFI the max timing reference and the main timing must be the same number.
Number of Gears: This tells the system the number of gears used in the transmission. This information can
be used a variety of ways depending on the functions and modules used in the system.
Ignition Type: Found under General Settings, this option allows a user to select between using the Power
Grid Ignition, PN 7720, or one of the MSD legacy ignitions.
DIAGNOSTIC LED INDICATOR
There is an LED that monitors the status of the system and allows the user to quickly know if all systems
are working properly, recording is in process, or if there are errors. The possible conditions of the light are
listed and explained below:
OFF – No power to the unit
1 Seconds ORANGE – Power ON light test
10 Seconds ORANGE – Slew/Time Rev Limiter Active (alert active for 60 minutes of power on after
module is disconnected)
Blinking ORANGE – Recording in process
Blinking GREEN – Input trigger (Mag or Points) below 500 rpm without Alerts
Blinking RED – Input trigger (Mag or Points) below 500 rpm with Alerts
GREEN – Running with no active Alerts
RED – Running with active Alert
CAMSHAFT SYNCHRONIZATION
This is used only in applications where the individual cylinder timing is going to be used. The fiber optic
connector communicates when the #1 cylinder fires. With this information, the controller knows which
cylinder is being fired allowing for the individual cylinder timing capabilities. Only the MSD Fiber Optic
Inductive Pickup Kit, PN 7555 will work for this system. Cam-sync’s cylinder #1 identification is also used
in the data acquisition recordings.
GEAR SHIFT
In the Gear Shift selection the user can set items such as launch and shift delay so that the system will not
have a false shift detected immediately after launch or a shift should there be an rpm drop for any other
reason.
Launch Delay: The amount of time in seconds after the launch that the system will ignore an rpm drop to
prevent false shift detection. This can be set from 0.00 to 10.00 in .01 second increments.
Shift Delay: The amount of time in seconds after sensing a shift that the system will ignore an rpm drop to
prevent false shift detection. This can be set from 0.00 to 10.00 in .01 second increments.
1->2 Shift: By setting the rpm drop the user tells the system how to sense when the car is being shifted
during a run. The setting is controlled by a drop down list with rpm from 200 – 1,500 or can be set
to be activated by a Step Retard wire instead. The number of shifts that is shown is controlled by
the number of gears the system is set to in the Settings – General tab.
