Controller requires wideband sensor so this listing is for replacing a failed Spartan 3 Lite or Spartan 2 controller, or for those who already have a Bosch LSU 4.9 wideband sensor and need a controller.
Go twice as fast! With a response time of just 7ms, Spartan 3 Lite V2 is more than twice as fast as any Wideband O2 Controller on the planet. Direct replacement for the discontinued Spartan 2.
Spartan 3 Lite V2 features the latest technologies; Bosch LSU 4.9 or LSU ADV Wideband Sensor.
Spartan 3 Lite V2 is designed with Megasquirt in mind, Megasquirt users can enjoy the most accuracy with Spartan 3 than with any other brand of Wideband Oxygen Controller through the use of the analog output for wiring to a gauge or ECU/Datalogger.
- Standalone ECU's (Such as PiMP, PiMPx, PiMPxs, PiMPxshift, Microsquirt) require both the controller & sensor
- Controller requires Bosch LSU 4.9 Sensor for use (or LSU ADV sensor if you configure via serial terminal for that sensor).
- Available with and without Solid AFR Gauge
- If you want to run dual widebands, you need two controllers and two sensors
Features:
- 7ms Response Time
- Compatible with Bosch LSU ADV and Bosch LSU 4.9 sensor. Bosch's newest sensor, LSU ADV, provides a 20x resolution increase over the LSU 4.9. Using LSU ADV sensor requires user to change the sensor settings using a serial terminal.
- 1x Programmable Linear voltage output
- 1x Simulated Narrowband output
- Spartan 3 Lite V2 does not have CAN Bus
- Lambda range of 0.6 (Lambda) to 3.4 (Lambda), equivalent to 8.82 (AFR) to 50 (AFR) for gasoline
- Analog Output Scale: 0v = 10.0:1 AFR, 5v = 20.0:1 AFR
- Smart Heat-up; Temperature Triggered Heating, Spartan 3 Lite v2 will wait for the Oxygen sensor to be heated to 662F by engine exhaust gases before heating up the sensor
- Does not require Free Air Calibration but it is available. Recommended only for clone LSU 4.9 sensors
- Serial Port
- ARM Cortex M4
- UART
- 0.1% tolerance components for all components that affect accuracy
- Programmable Linear Output for Increased Sensitivity in your Engine's Intended AFR Range, or to work with Multiple Gauges
- Separate grounds and power connections for LSU Heater and electronics for improved noise performance
- 4 layer Printed Circuit Board
- Water, Dust, and Dirt Resistant
- 2-Year Controller Warranty
- 3-Month Wideband Sensor Warranty
