Warning
•Do not connect or disconnect the Lambda Sensor while MegaSpartan is powered, only do so when MegaSpartan is unpowered.
•The Lambda Sensor gets very hot during normal operation, be careful when handling it.
•While the Lambda Sensor is in an active exhaust stream it must be controlled by MegaSpartan. Carbon from an active exhaust can
easily build up on an unpowered sensor and ruin it.
•Lambda sensor life when used with leaded fuels is between 100-500 hrs. The higher the metal content the shorter the life of the
Lambda sensor.

Not currently used. This terminal is protected by; fuse, diode (reverse
polarity protection), and Transient Voltage Suppressor.
For PowerA and PowerB each should be connected through the supplied fuse holders and 15A fuses. The best place to tap power is generally
after the ignition switch or any other source of power that is always “live” when the engine is running. If the Lambda sensor is in an active
exhaust stream and unpowered, carbon from an active exhaust can easily build up on an unpowered sensor and ruin it.
You can ground all the grounds to the same point.
Lambda Sensor Installation
The Lambda Sensor should be installed between the 10 o’clock and the 2 o’clock position,
less than 60 degrees from vertical, this will allow gravity to remove water condensation
from the sensor.
For all Oxygen sensor installations the sensor must be installed before the catalytic converter.
For normally aspirated engines the sensor should be installed about 2ft from the engine exhaust port. For Turbocharged engines the sensor
should be installed about 3ft from the engine exhaust port after the turbocharger. For Supercharged engines the sensor should be installed 3ft
from the engine exhaust port

TunerStudio Configuration for MegaSquirt 2
In TunerStudio under “Basic Setup” select “EGO Control”.
For MegaSpartan with single Lambda, set “EGO Sensor Type” to “Single Wide Band”, set “1st EGO sensor port” to “Remote ADC0”. “Burn”the
settings to your MegaSquirt.

For MegaSpartan with dual Lambda, set “EGO Sensor Type” to “Dual Wide Band”, set “1st EGO
sensor port” to “Remote ADC0”, set “2nd EGO sensor port” to “Remote ADC1”. Burn the settings
to your MegaSquirt.
Under “Tools” select “Calibrate AFR Table”
Set “EGO Sensor” to “Innovate LC-1/LC-2 Default”. “Write to Controller” your settings.

TunerStudio Configuration for MegaSquirt 3
In TunerStudio under “Fuel Settings” select “AFR/EGO Control”
Set “EGO Sensor Type” to “Wide Band”. Set “Number of Sensors” to
appropriate number of Lambda sensors.
For each Lambda sensor, set the “EGO X Port” to “CAN EGO”.
Set “MS3X Inj A” to “MS3X Inj H” to the appropriate EGO#. EGO1 is
MegaSpartan Lambda 1 … EGO8 is MegaSpartan Lambda 8. For example, if
you set “MS3X Inj A” to “EGO1” then MegaSquirt will assign MegaSpartan
Lambda 1 to Injector A.
“Burn” settings to your MegaSquirt.
