Im wiring a aem uego gauge to the ecu in order to datalog with hondata, and I was planning on welding a seperate bung for my uego sensor. If I keep the stock sensor in place and run the uego do I still tap in my analog wire(0-5V) to the Ecu oxygen sensor wire(D14 or D7??? on Obd1Gsr). Wouldnt it be then picking up 2 signals, one from my stock sensor and one from my aem sensor. Can someone explain to me how im supposed to do this, I dont quite understand.

One input = one signal

So if Hondata datalogs the primary O2 input, and you want to datalog the AEM wideband output, then you can't have the narrowband O2 hooked up in addition to the AEMs.

Is there some other unused analog input on the ECU that Hondata can log?

So how do I run both and datalog at the same time or is it not possible cause if the stock o2 sensor wire isnt goin to the ecu wont that screw up my closed loop mode?

There is ONLY one O2 sensor input on the ECU - you EITHER give it the narrowband OR the wideband output and then datalog. Will the ECU be able to use the wideband output in order to keep closed loop operation - I dunno, but I do know that if you give it the narrowband output, closed loop will work as thats how it was originally designed.

So it is NOT possible to run both at the same time into the same input on the ECU.

 

So I should make a adapter plug to switch to datalog and to run closed loop. I notice when I run hondata with no uego only the stock one I get all kinds of looney a/f ratios in hondata.

Well you don't want to datalog the narrowband output and you 'may not' want to use the wideband output for closed-loop operation - so yes, make an adpater plug that will allow you to switch between the two.

I say 'may not' because I dunno if the Hondata would play nicely with the wideband O2 output during closed loop operation - but since you have an adpater plug now + the ability to enable/disable closed-loop operation whenever you want, I can't see it hurting anything to try closed loop with the WBO2 and if things aren't koscher, then switch to the narrowband for closed-loop.
