A purebred Wideband Oxygen Controller with no excess. Spartan 2 is our next generation Wideband Oxygen Sensor Controller for the Bosch LSU 4.9 Wideband Oxygen sensor.

Spartan 2 is the first Wideband Oxygen Controller to use all extended temperature components, this means Spartan 2 offers the widest operating temperature; -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 is the first Wideband Oxygen Controller to use all automotive grade components, it is the same quality components Automotive 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 0.01 Lambda 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.

Spartan 2 is designed with Megasquirt in mind, Megasquirt users can enjoy the most accuracy with Spartan 2 than with any other brand of Wideband Oxygen Controller through our easy to use Output Sequencer feature. To find out more please follow the link here



Spartan 2 utilizes the 14point7 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
AFR/Lambda range, 0.68[Lambda] to 1.36[Lambda], 10[AFR] to 20[AFR] equivalent for gasoline
0.01 Lambda accuracy without the need for any calibration
Utilizes our patent pending Binary Drive technology; no other system is more digital
Linear Output allows easy interfacing with gauges, fuel management systems, and data-loggers
Linear Output: 0[V] @ 0.68[Lambda] linear to 5[V] @ 1.36[Lambda], 10[AFR] linear to 20[AFR] equivalent for gasoline
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 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
