Description
The Spartan 3 Lite v2 is a streamlined, high-precision wideband oxygen controller designed for the Bosch LSU 4.9 and LSU ADV sensors. Built for performance without excess, it offers all the essentials for reliable wideband monitoring.
With both a programmable analog linear output and a programmable simulated narrowband output, the Spartan 3 Lite v2 is compatible with most gauges, ECUs, and data loggers. The advanced design, premium components, and thorough factory calibration ensure an impressive 0.01 Lambda accuracyāno additional calibration required.
Installation is straightforward: Spartan 3 Lite v2 is engineered for durability and water resistance, making it suitable for engine bay installation. Most setups require only 4 wires.
14Point7 backs this product with a 2-year warrantyādouble that of competing products.
Spartan 3 Lite v2 Features:
- 10ms Response Time: Delivers quick and precise readings.
- 1x High-Performance Programmable Analog Output: Default setting is 0-5V with a 10-20 AFR linear range.
- 1x Programmable Simulated Narrowband Output: Ensures broad compatibility with various devices.
- Sensor Compatibility: Works with Bosch LSU 4.9, Bosch LSU ADV, and compatible clone LSU 4.9 sensors. The LSU ADV provides 20x better resolution compared to the LSU 4.9.
- Lambda Range: Measures from 0.6[Ī»] to 3.4[Ī»], equivalent to 8.82 to 50 AFR for gasoline.
- %O2 Measurement: Covers a range from 0% to 21% O2.
- Lean Burn Mode: Ideal for lean burn applications.
- Smart Heatup: Temperature-triggered heating allows Spartan 3 Lite v2 to wait until exhaust gases heat the sensor to 350Ā°C before engaging the heater.
- Output Sequencer: Provides dual-level precision voltage signals for easy AFR/Lambda accuracy checks and calibration. Useful for MegaSquirt users.
- No Free Air Calibration Needed: Calibration-free for standard sensors; optional for clone LSU 4.9 sensors.
- Sensor Heater Status LED Output: Included LED tracks sensor temperature.
- UART Connectivity
- ARM Cortex M4 Processor
- Precision Components: 0.1% tolerance for components impacting accuracy.
- Improved Noise Performance: Separate grounds for the LSU heater and electronics.
- Warranty and Guarantee: Backed by a 2-year warranty and a 60-day money-back guarantee.
Note: Lambda sensor carries a 3-month warranty.
Additional Features and Specifications:
- 8ft cable length
- Operating Temperature: -40[C] to +105[C]
- Water, dust, and dirt resistant
If the Spartan 3 is ordered with a sensor, it will be pre-configured for that specific sensor.Ā Users can easily adjust the sensor settings using a serial terminal.
