I have a Neptune RTP installed on my turbo B series and building the base map and getting it to run was a snap. However, I just installed an AEM UEGO wideband and I want to be able to datalog. I replaced the stock O2 sensor with the AEM and disabled closed loop in Neptune, but how do I get the unit to datalog? Specifically, which output from the AEM do I use (5v or serial) and which input do I run it to on the ECU? I have gone through the instructions and they explain how to datalog, but I can't find info on actually hooking it up.

Thanks in advance for your help.

 

The 5v to any of the 4 available inputs, which are listed under logging in preferences.

 

I would run the 0-5v output from the wideband to the ecu at pin location D10, which is ELD. Then enable wideband logging via ELD in the program.

I also suggest removing the resistors at R136 and R138 when logging through the eld input.
