What's going on guy's, so I am running the AEM infinity on my 8 and I want to run the wideband o2 sensor to the Ecu but I would also like to have the gauge still installed so I can see what's going on with the AFR's. What is the best way to set up the gauge so I can see what the ECU is seeing?

 

If your gauge outputs AEM Net, just tie those two wires back into the AEM Net on the Infinity. Done.

 

That is super simple thank you for the response.

 

I ordered the wideband extension harness from map so I can plug the O2 sensor directly to the Infinity and then I run the Green/White wire from the gauge to the aemnet plug? Should I just keep the power and ground wire where they are for the gauge or run all 4 to the AEMnet? As long as the gauge is getting power it should not matter right?

 

Don't even run the extention. There is no benefit. Just set it up in the wizard under input functions - lambda input - x series 1 and call it a day. I had a debate with an AEM tech and he said if you already have the gauge, its a waste of money to buy the adapter to run it directly to the ecu since they both react just as fast.

 

oh ok yeah that makes sense I guess I will be returning the other harness and just hook it up how you said.

 

I mean you can do it how you said but at that point pull the gauge and harness out, sell them without the o2 sensor and go buy an aem net gauge. That way you can monitor whatever the ecu sees from that one gauge.

 

done deal lol
