Spartan 3 Lite v2
by 14Point7
Spartan 3 Lite v2 is a purebred Wideband Oxygen Controller for the Bosch LSU 4.9 and LSU Adv Wideband sensor with no excess.
Spartan 3 Lite v2 is equipped with both a programmable analog Linear Output and programmable Simulated Narrowband Output that is compatible with most gauges, ECUs, dataloggers, etc…
The advanced design, highest quality components, and extensive factory calibration means 0.01 Lambda accuracy without the need for any calibration.
Easy install; Spartan 3 Lite v2 is made durable and water-resistant to be installed in the engine bay, most installations require only 4 wires.
14Point7 stands behind this product with a warranty that is twice as long as any competing product, 2 years
Spartan 3 Lite v2 Features:
- 10ms Response Time
- 1x High Performance Programmable Analog Output, default is 0-5v 10-20 AFR Linear Output
- 1x Programmable simulated narrowband output
- Compatible with Bosch LSU 4.9, Bosch LSU ADV, and clone LSU 4.9 sensors. The LSU ADV sensor provides a 20x resolution increase over the LSU 4.9.
- Maximum Lambda range of 0.6[Lambda] to 3.4[Lambda], equivalent to 8.82[AFR] to 50[AFR] for gasoline
- %O2 range of 0%O2 to 21%O2
- Lean Burn mode for lean burn applications
- Smart Heatup; Temperature Triggered Heating, Spartan 3 Lite v2 will wait for the Oxygen sensor to be heated to 350C by engine exhaust gases before heating up the sensor
- Output Sequencer provides a dual-level precision voltage signal to the Linear Output. This allows you to easily check that the AFR/Lambda seen by any device connected to the Linear Output is accurate, and if not, to generate a 2 point calibration to achieve perfect accuracy.

- Does not require Free Air Calibration but FAC is available. Recommended only for clone LSU 4.9 sensors
- Sensor Heater Status LED Output (LED included) allows the tracking of sensor temperature.
- UART
- ARM Cortex M4
- 0.1% tolerance components for all components that affect the accuracy
- Separate grounds for LSU Heater and electronics provide improved noise performance
- 2-year warranty
- 60-day money-back guarantee
- Spartan 3 Lite v2 does not have CAN Bus
Note: Lambda sensor carries a 3-month warranty
Additional Features and Specifications:
- 8 ft cable length
- Operating Temperature: -40[C] to +105[C]
- Water, dust, and dirt resistant
Pricing:
- Spartan 3 Lite v2 without LSU @ $82.50 USD
- Spartan 3 Lite v2 with LSU 4.9 @ $135 USD
- Spartan 3 Lite v2 with LSU ADV @ 182.50 USD
If Spartan 3 Lite v2 is ordered with a sensor, Spartan 3 Lite v2 will ship configured for that sensor. If Spartan 3 Lite v2 is purchased without a sensor then Spartan 3 Lite v2 will ship configured for the LSU 4.9, the user can change the sensor settings using a serial terminal. You can also request LSU 4.9 and LSU ADV configuration at the time of ordering using the order notes
