I want to use the wide band O2 sparkandfuel.com is selling but i'm not sure if i need to get the LC-1 Wideband Controller. Can I just get the Replacement Bosch LSU4.2 5-wire, wide-band O2 sensor? What do i need for a successful install?

 

You need a controller... The MS won't directly control a wideband sensor.

The controller controls the sensor, and then outputs a 0-5v signal that the MS can use to determine AFR/Lambda.

 

Ok, thank you for clearing that up for me.
