Either your wideband is off your car is a ticking time bomb. At what part of the exhaust did you put the sensor?

 

I have a megan downpipe, megan midpipe (resonated) and megan catback.

The megan catback has a bung in it so I used that (similar to where the stock secondary sensor is)

the stock secondary sensor is in the bung in the catback.

 

That is way too far back for that sensor, it needs to be right about 18inches from the turbo.

 

see my other post...

pics in there of the install...

 

Well its a little too far back and at a bad angle

 

well an afr of 10 is too rich. loggin would help u get an idea on how the car is running and if its way back and its still that rich then there is something definitely wrong. the further back the wideband the leaner it tends to read.

 

The car seems to be running fine... why would AMS have tuned it that rich? I was only tuned last month and I havent done any other mods since then but install this gauge.

 

ams is a great shop. just trying to help u figure out why the afr is showing 10s. well i guess if u know someone with a bosch wideband sensor then u could try that and see if ur sensor is band.

 

Free air calibrate the sensor and get it logging by pinning the analog output into your ECU then log some pulls and make adjustments as needed

 

There is no such thing as logging or calibrating this sensor.

This is not an AEM wideband.

I have a better thread started on this problem:
