Go twice as fast! With a response time of just 10ms, Spartan 3 is more than twice as fast as any Wideband O2 Controller on the planet.

Spartan 3 Lite features the latest technologies; Bosch LSU 4.9 or LSU ADV Wideband Sensor.

Spartan 3 Lite 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 flash the firmware for that sensor).
• Available with and without Solid AFR Gauge
• Can use our Perfect Tuning CAN gauge instead of Solid AFR Gauge to add additional features and programmable I/O's
• If you want to run dual widebands, you need two controllers and two sensors
  
  Features:

• 10 ms 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 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
  
• Serial Port
• ARM Cortex M4
  
• 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 and improved voltage protection
  
• 4 layer Printed Circuit Board
• 2-Year Controller Warranty, 3 Month Sensor Warranty
• 60-day Money Back Guarantee
