by 14Point7
Price $139.00

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, and USB.

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

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

Spartan 3 Features:

  • 10ms Response Time
  • 1x High Performance Programmable Analog Output, default is 0-5v 10-20 AFR Linear Output
  • 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.
  • Lambda range of 0.6[Lambda] to 3.4[Lambda], equivalent to 8.82[AFR] to 50[AFR] for gasoline
  • %O2 range of 0%O2 to 21%O2
  • Lean Burn mode for lean burn applications
  • CAN Bus support for the following ECUs; Megasquirt 3, Adaptronic, Link, Haltech, HP Tuners, as well as YourDyno dyno controller are supported. More supported devices coming soon via firmware update
  • CAN Bus output of Lambda or %O2
  • Smart Heatup; RPM Triggered Heating of the oxygen sensor for MS3 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 
  • Output Sequencer provides a dual-level precision voltage signal to the high performance analog Output. This allows you to easily check that the AFR/Lambda seen by any device connected to the analog Output is accurate, and if not, to generate a 2 point calibration to achieve perfect accuracy. MegaSquirt users, check out how to use the Output Sequencer for maximum AFR accuracy here
  • Does not require Free Air Calibration but FAC is available. Recommended only for clone LSU 4.9 sensors
  • Compatible with Torque OBD for Android to display AFR
  • Onboard FTDI based serial-USB converter
  • ARM Cortex M4
  • 0.1% tolerance components for all components that affect accuracy
  • Separate LSU Heater ground and Electronics ground for improved noise performance and accuracy
  • 2-year warranty
  • 60-day money-back guarantee

 Note: Lambda sensor carries a 3-month warranty

 

Additional Features and Specifications:

  • 8 ft cable length
  • Operating Temperature: -40[C] to +105[C]
  • Water, dust, and dirt resistant

Pricing:
