spartan2 wideband 14point7

Features / Specification from 14point7 website
Spartan 2 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
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

Simulated Narrowband Output allows you to install a Wideband O2 Sensor in place of your Narrowband O2 sensor
Simulated Narrowband switch point @ 1[Lambda], 14.7[AFR] equivalent for gasoline

Easy 4-wire installation for most setups
