Installation Instructions

As we now have many different types of product, we have separated the instructions into separate documents. You will find the links below for your type of EFIE or other device, and the correct instructions.

However, despite the variety of devices we offer, the instructions are pretty similar for all of them. There are only 2 basic types of oxygen sensor. These are the narrow band and wide band types. Each of these 2 types requires a slightly different installation. Also, in the narrow band variety we have the Digital Narrow Series of devices. These install the same as any other narrow band type of EFIE, and the only difference is how you set the Digital type.
