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.

CHANNELS

CHANNEL

Description

ENGINE SPEED

The Speed of the motor in RPM

IGNITION TIMING

Ignition timing referenced to Top Dead Center (TDC)

MAP

The Intake Manifold Absolute Pressure in kPa or PSIA

LAUNCH

Launch wire: activated = 1; not activated = 0

STEP RETARD

Step Retard wire: activated = 1; not activated = 0

ECT

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

IGNITION VOLTAGE The voltage being supplied to the unit and the coils. It is important that it

remains over 12V to supply proper power to them.

MAP FAULT

Indicates the MAP sensor is open or shorted

BATTERY FAULT

Activates if voltage drops below 9V or goes above 18V

CAM FAULT

Indicates a problem with the camshaft position sensor (CMP). It will acti-

vate if RPM is detected but no cam sensor signal is detected

CRANK FAULT

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.
