Wideband errors

I have a 30-4110 monitor/ controller with a Bosch 4.9 LSU sensor. Installed in a 13b turbo rx7 about 15 inches from the turbine outlet in the exhaust. Running no exhaust other than that right now. Started the car for the first time the other day and took it around the street, the wideband is reading full lean with three dashed lines. When the mo it or turns on, it reads through the default numbers then reads P00, then REN, then goes to dashed lines again. It has worked briefly the other day at first start up. 

I’m wondering if the large amount of engine assembly oil that got burned on first start could have damaged the sensor? Any thoughts?

The sensor is about 3 inches

The sensor is about 3 inches away from open air. However, I tried wrapping a gasoline soaked cloth around the sensor and it still reads three dashes.

With the key ON and the engine OFF, when your gauge has booted up and warmed the sensor to "---"

What will your gauge read if you unplug the sensor? This will help tell us whether or not the issue is with your gauge or the sensor.

I’m having an issue with mine

I’m having an issue with mine, it came with the car not sure of what model number it is. So basically when I turn the car on it’ll show three bars in a shape of a upside down “u” then after it’ll go to one bar, the analog works tho. But numbers do not show what could be the problem?
