Hondata

I am hooking my wideband up to hondata and I was going to run the 5v white wire to my ELD wire b/c of the 0-5v on the circut compared to 3.8Xv coming from the 02 D10 wire.

In order to let my car run in open loop correctly does the 5v white wire from my AEM wideband have to be hooked up to my 02 wire (d14)? Or can it still be hooked up to D10 ELD and set to open loop? I only have one 02 bung on my header and just wanted to run the car in open loop. Is this bad or is it perfectly fine to do this? I have searched but couldn't find to much on this. Some things I have read lead me to believe that it has to be to the 02 wire. But if the car is in open loop does that matter? It should be running off the stock tune via hondata correct?

Thanks,
Ryan

maybe its just me, but your question seems a little confussing.

running the white wire to D14 is fine as long as set you imput appropreitly and that you relize that you will not be able to run the ecu in closed loop.

from the sound of it, if you dont plan on running a second bung which any exaust shop could put on for less then $50 and just remove the stock o2 sensor. I belive the ecu will throw a CEL if you run the wire to pin D10(eld) becuause it going to be looking and trying to heat a sensor thats not there.

I know it is confusing lol.

I have it hooked to the 02 now. I disabled the o2 heater and set the input to 02. And the car is in open loop. I'm working it out though. Thanks for responding.

For high HP motor there don't run close loop
If your motor is daily drive and weekend worrior
Is better runs wide and narrowband sensor

If you use a plx wide band setup you can use 1 o2 sensor that sends the ecu both NB and WB signal. The aem would only allow for WB open loop operation. The ecu would not use the o2 sensor for af calculations in open loop.

I just installed my AEM wideband.

I connected the white wire to ELD on my EG. Seems to work fine for me.

I run open loop at all times because it is tuned. I dont have a stock o2 sensor.

can expand on this?
does that mean that there is only one wire but it will datalog a WB reading while tuning but report a NB reading to the ecu for closed loop operation?

There are 2 wires(2 outputs) from the PLX control unit(with 1 O2 sensor attached),1 wire gives a narrowband simulation to D14 so u can run closed loop while still having the 2nd wire spitting out a wideband signal to your chosen input at the ECU.

U can simulate narrowband over the AEM's single output by selecting P4 on the gauge selector switch to run closed loop,but obviously u would have to have its single output wire connected to D14 at the ECU(or switch the wire between D14 & your chosen wideband signal input) & would not be able to both datalog AF & run closed loop at the same time.

I dont have an AEM so what the actual AEM gauge reads when switched to P4,u will have to find out for yourself,it is unclear from what ive read of the AEM gauge whether it will show a narrowband reading or wideband reading when set to P4.
