INSTALLATION INSTRUCTIONS
DATA ACQUISITION
The data recorder on the LS Ignition system is a programmable 8MB storage system. It is meant to
be a recording device to observe RPM, timing, input activations and a number of other different pa-
rameters while racing down the track. Once the memory is full, the system will stop recording data
until the user deletes some of the recordings.
SETTINGS
DATA ACQUISITION: Master Enable/Disable switch
START RECORDING ABOVE: The engine speed must be greater than this to begin re-
cording.
ACTIVATE WITH LAUNCH INPUT: If this is enabled, recordings will not start unless the
“Launch” wire is activated. If it is disabled, recordings can start whenever the RPM
conditions are met.
STOP RECORDING BELOW: If the engine speed falls below this, the recording will stop.
MAX RECORDING TIME: This is the longest any single recording can be. If the time is
expired and all other conditions are still met a new recording will automatically begin.

Description
The Speed of the motor in RPM
Ignition timing referenced to Top Dead Center (TDC)
The Intake Manifold Absolute Pressure in kPa or PSIA
Launch wire: activated = 1; not activated = 0
Step Retard wire: activated = 1; not activated = 0
Engine Coolant Temperature. It will show -40°C if not connected, but the
controller will default it to 50°C in the temperature timing control
The voltage being supplied to the unit and the coils. It is important that it
remains over 12V to supply proper power to them.
Indicates the MAP sensor is open or shorted
Activates if voltage drops below 9V or goes above 18V
Indicates a problem with the camshaft position sensor (CMP). It will acti-
vate if RPM is detected but no cam sensor signal is detected
Indicates a camshaft sensor (CMP) signal is detected, but no engine speed
is detected - likely resulting from a Crankshaft Position Sensor (CKP) fault
Note: The system has a limit of 10 minutes of recording every time the Data Acquisition is en-
abled; that includes the initial enable at power up. After the limit is reached, the user must
disable and re-enable the Data Acquisition in order for the system to continue recording.
