I've had the aem wideband wired to the stock ecu for some time. I got a vipec and I want to ensure that the vipec doesn t see a varying wideband reading from ground offset just like the stock ecu tends to. Where is the best place to ground the aem so that the grounding is infallible.

Can i tie it into a sensor ground pin to the ecu ? I will be pinning it to the factory front o2 sensor. And also using it in that location. As I will be using quick tune and wot fuel corrections ..

 

The battery negative is the best place IMO.

 

Is there any equivalent spots in the cabin / loom? Would the sensor ground cause interference with anything ?

 

Ideally, the best place to wire the wideband is the same place the stock ecu is grounded. A sensor ground would work, but if there's a ground to the chassis from the ecu, I'd use that.

 

Gotcha thanks!
