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 LiteV2 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
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
