Description
The Spartan 3 V2 is a streamlined, high-performance CAN bus-enabled wideband oxygen controller, engineered for precision. It supports both Bosch LSU 4.9 and LSU ADV wideband sensors and delivers superior accuracy without unnecessary extras.
Equipped with two programmable analog outputs—one high-performance and one standard—along with CAN bus and USB connectivity, the Spartan 3 V2 offers versatile integration options. Thanks to advanced design, premium components, and meticulous factory calibration, you can count on 0.01 Lambda accuracy without any manual calibration required.
Installation is straightforward and robust, with a durable, water-resistant design that allows for engine bay mounting. Most setups need only five wires, making it quick and easy to get started.
Backed by an industry-leading 2-year warranty—double the coverage of most competitors—Spartan 3 V2 ensures reliability and peace of mind.
Spartan 3 V2 Wideband Features:
- 10ms Response Time: Fast and accurate oxygen sensing for optimal performance.
- 1x High-Performance Programmable Analog Output: Default output is 0-5V with a 10-20 AFR linear range, customizable to suit your needs.
- 1x Standard-Performance Programmable Analog Output: Default setting is sensor heater status, user-changeable to simulate narrowband output.
- Sensor Compatibility: Supports Bosch LSU 4.9, Bosch LSU ADV, and compatible LSU 4.9 clone sensors. The LSU ADV offers a 20x resolution improvement over the LSU 4.9.
- Wide Lambda Range: Measures from 0.6[λ] to 3.4[λ], equivalent to 8.82 to 50 AFR for gasoline.
- %O2 Measurement: Measures oxygen from 0% to 21%.
- Lean Burn Mode: Ideal for lean burn applications.
- CAN Bus Support: Compatible with ECUs like Megasquirt 3, Adaptronic, Link, Haltech, HP Tuners, and YourDyno, with more devices to be supported via firmware updates.
- CAN Bus Output: Delivers Lambda or %O2 data over CAN bus.
- Smart Heatup Functionality:
- RPM-Triggered Heating: Controlled via MS3 ECU over CAN bus.
- Temperature-Triggered Heating: Waits for exhaust gases to heat the sensor to 350°C before engaging the heater.
- Output Sequencer: Provides dual-level precision signals for easy AFR/Lambda accuracy checks and calibration. Ideal for MegaSquirt users.
- No Free Air Calibration Needed: Calibration-free for standard sensors; optional for clone LSU 4.9 sensors.
- Torque OBD Compatibility: Works with Torque for Android to display AFR.
- Integrated USB Connectivity: Onboard FTDI-based serial-to-USB converter.
- High-Quality Components: ARM Cortex M4 with 0.1% tolerance components for critical accuracy.
- Improved Noise Performance: Separate LSU heater ground and electronics ground for enhanced accuracy.
- Reliable Warranty: 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 V2 is ordered with a sensor, it will be pre-configured for that specific sensor. Users can easily adjust the sensor settings using a serial terminal.
