Note: The Spartan 3 Lite replaced the Spartan 2 controller.
Spartan 3 Lite v2 Features:
- 10ms Response Time
- 1x Programmable linear voltage output for Lambda/AFR/%Oxygen
- 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.
- Default Lambda range of 0.68[Lambda] to 1.36[Lambda], equivalent to 10[AFR] to 20[AFR] for gasoline
- 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
- 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]
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
