Controller requires wideband sensor so this listing is for replacing a failed Spartan 3 or Spartan 2 controller, or for those who already have a Bosch LSU 4.9 wideband sensor and need a controller. 

Spartan 3 v2 is a purebred CAN bus enabled Wideband Oxygen Controller for the Bosch LSU 4.9 and LSU Adv Wideband sensor with no excess.

Spartan 3 v2 is equipped with, 1x high-performance programmable analog output, 1x standard-performance programmable analog output, CAN bus, Android, and USB.

The advanced design, highest quality components, and extensive factory calibration means 0.01 Lambda accuracy without the need for any calibration.

Spartan 3 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 CAN connectivity allowing 2 wire connection to the ECU whether you use single or dual widebands! Analog output also available for wiring through the stock o2 sensor wiring. 

Easy install; Spartan 3 v2 is made durable and water-resistant to be installed in the engine bay, most installations require only 5 wires.

14Point7 stands behind this product with a warranty that is twice as long as any competing product, 2 years

  • Standalone ECU's (Such as PiMP, PiMPx, PiMPxs, PiMPxshift, Microsquirt) require both the controller & sensor
  • Controller requires Bosch LSU ADV Sensor for use (or LSU 4.9 sensor if you configure via serial terminal for that sensor).
  • Available with and without Solid AFR Gauge or 10-Color Configurable Gauge
  • Can use our Perfect Tuning CAN gauge instead of Solid or 10-Color Configurable 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. Can run zero, one, or two gauges.

    Features:
  • 10ms 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 4.9 sensor requires user can change the sensor settings using a serial terminal.
  • 1x High Performance Programmable Analog Output, Default is 0-5v = 10-20 AFR linear
  • 1x Standard Performance Programmable Analog Output, default is Sensor Heater Status. User changeable to Simulated Narrowband Output
  • Compatible with Bosch LSU 4.9, Bosch LSU ADV, and clone LSU 4.9 sensors. The LSU ADV sensor provides a 20x resolution increase over the LSU 4.9. Pre-programmed for ADV sensor
  • Lean Burn mode for lean burn applications
  • CAN Bus support for the following ECUs; Megasquirt 3 (MS3), Adaptronic, Link, Haltech, HP Tuners, as well as YourDyno dyno controller are supported. More supported devices coming soon via firmware update
  • CAN Bus connectivity to any version of PiMP ECU's frees up an additional analog input
  • CAN Bus output of Lambda or AFR
  • Smart Heatup - RPM Triggered Heating of the oxygen sensor for MS3 (PiMPx/PiMPxs/PiMPxshift) ECU over CAN
  • Smart Heatup - Temperature Triggered Heating, Spartan 3 will wait for the Oxygen sensor to be heated to 350C by engine exhaust gas before heating up the sensor 
  • Does not require Free Air Calibration but it is available. Recommended only for clone LSU 4.9 sensors
  • Output Sequencer provides a dual-level precision voltage signal to the Linear Output. This allows you to easily check that the AFR/Lambda seen by any device connected to the Linear Output is accurate, and if not, to generate a 2 point calibration to achieve perfect accuracy.
  • Spartan 3 V2 is compatible with Torque OBD App for Android devices to display AFR
  • Lambda range of 0.6 (Lambda) to 3.4 (Lambda), equivalent to 8.82 (AFR) to 50 (AFR) for gasoline
  • Onboard FTDI based serial-USB converter
  • 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
  • Water, Dust, and Dirt Resistant - Can be installed in the engine bay
  • Compact Inline Design
  • 2-Year Controller Warranty, 3 Month Sensor Warranty
  • 60-day Money Back Guarantee

Additional Features + Specifications:

  • 8 ft Cable Length
  • Total Length with LSU ADV: 9 ft
  • Operating Temperature: -40C to +105C (-40F to +221F)
  • Accuracy:  0.012 (Lambda), RMS Error of Controller + Sensor
  • Resolution: 0.00067 (Lambda)
  • Response Time: 10(ms)
  • Spartan 3 V2 dimensions: 115mm x 60mm x 26mm

Includes:

  • Spartan 3 V2 Lambda Controller Configured for LSU ADV Sensor
  • 8ft Cable (Controller to Sensor)
  • USB Converter
  • 2x Fuse Holder
  • 2x 5 Amp Fuse (Replacement Included)
  • 2x 1 Amp fuse (Replacement Included)
  • o2 Bung (Optional)
  • o2 Bung Extra Tall Finned (Optional) (Additional Sensor Cooling when sensor is closer than 18" from turbo outlet or exhaust port)
