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
