I just got the AEM Wideband failsafe gauge and series 2 ems for my 04 s2000. I had a friend of mine, with exeperience with this kind of stuff but little experience with aemtuner, help me with it and we are not sure where to wire the afr and boost output wires from the gauge into the ecu. We tried to wire them into the D connector in order to avoid tampering with the factory harness as much as possible because I live in an area where I must still pass emissions so I will need to be able to swap the factory ecu back in as easily as possible.

We also have looked around in AEMtuner and online in order to figure out how to configure inputs into the ecu, and have come up with nothing.

So if anyone can tell me what pins these wires need to go to and how to configure it, that would be extremely appreciated.

 

I though AEM would monitor wideband feed back and you could set a kill incase it went too lean?

 

Are you referring to the failsafe gauge? It will monitor afr and boost on its own. Wideband o2 goes directly to gauge. Then there is a blue wire that goes to your failsafe option and two other wires, one for boost output and one for afr output. Those two should be wired to the ecu as far as I know. Just not sure where. Also not sure if I can wire the failsafe wire to the ecu and configure it to what I want
