• 14point7 Spartan Lambda Controller 2

Price is inclusive import tax from the USA.

Spartan 2 LB is a variant of our Spartan Lambda Controller 2 that is dedicated to Lean Burn applications. Spartan 2 LB reads oxygen concentration from 0[%] to 21[%] with a resolution of 0.1%. Spartan 2 LB is suitable for a wide variety of applications such as Lean Burn engine tuning, power generation, wood/coal/gas burners, and much more.

Spartan 2 LB is the first Wideband Oxygen Controller to use all extended temperature components, this means Spartan LB 2 offers the widest operating temperaute; -40[C] to 125[C], of any Wideband Oxygen Controller on the market. From the frozen Arctic Tundra to the baking heat of Death Valley, Spartan 2 is the Wideband Oxygen Controller you can rely on.

Spartan 2 LB is the first Wideband Oxygen Controller to use all automotive grade components, it is the same quality components OEMs use for mission critical electronic systems. Automotive qualified components offer increased reliability, increased resistance to electromagnetic interference, and exceptional durability when compared to non-automotive grade components.  

The advanced design, high quality components, and extensive factory calibration means  0.1% O2 concentration accuracy — without the need for any calibration.

14Point7 stands behind this product with a warranty that is twice as long as any competing product. With an unrivaled 60 day money back guarantee, you can buy with confidence and know that you are getting the absolute best.

Kit delivered with Bosch LSU4.9 wideband sensor!


Spartan 2 LB utilizes the Bosch LSU 4.9 Wideband O2 Sensor - a cost efficient Wideband O2 sensor providing 0.01 Lambda accuracy, fast response, and rated life of 100,000 km

Compatible with all fuels 

O2 range: 0[%] to 21[%]

0.1[%] O2 concentration accuracy without the need for any calibration

Linear Output allows easy interfacing with external systems

Linear Output: 0[V] @ 0[%] O2 concentration linear to 5[V] @ 21[%] O2 concentration

Our innovative Output Sequencer feature means our Wideband O2 Controllers to have the most accurate Linear Output on the market. You can be sure that any device connected to the Linear Output will receive the most accurate AFR/Lambda signal possible

The Output Sequencer provides a dual level precision voltage signal to the Linear Output. This allows you to easily check that the O2 concentration seen by any device connected to the Linear Output is accurate, and if not, to generate a 2 point calibration to achieve perfect accuracy

Easy 4-wire installation for most setups

A Two-Year Warranty that is twice as long as any competing product
