ok i lost the thread i was participating in on howto hook up a plx wideband to the hondata ecu to datalog AND also replace the stock narrowband sensor. im ready to wire it up now and forgot. i think it was something like hook wideband output to D14 or D10 and narrowband output to D14 or D10?

thanks!

 

no one knows what im talking about?

well cant i just wire the narrowband wire into the ecu and not into a o2 plug?

doesnt s300 have a option to disable the 02 heater??

 

Yes, you can disable the heater and the information for installing a WB can be found in the help files.

 

so then i can just wire the narrowband out put strait to the ecu and not to a 02 plug and plug it into the harness like hondata says. they need to update their ****.

wideband is already installed. it has been for over a year. but im switching to hondata.

 

Did you read the link? The link has all of the info you need to install a wideband. I used that link to install my Greddy AF meter and my Techedge.

You need to get another harness side O2 plug.
Install a loopback on the heat wires (A25 to A6) with a 1k ohm resistor
Sensor Narrowband output connects to plug wire that leads to D14 on the ECU.

i dont think you get it...you do all that **** with the o2 plug (or resistors) so it wont throw a CEL. BUT hondata s300 has a option to disable o2 heaters. so no need to do that, just wire it into the ecu..

all i needed to know out of this thread was which one went to D14 and which one went to D10..

 

Click the closed loop tab after you open the tune and select "Disable o2 heater".

I have a Hondata S300 with a Techedge 1.5 wideband. o2 Heater is turned off and the narrowband output is connected to D14.

Did you check the Hondata forum? I did a search and found lots of threads over there!!

 

i think you mean this one. https://honda-tech.com/zerothread?id=1585145

edit: looks like you will need a switch for the white and gray wires to d14. unless you wanna run in open loop all the time and datalog. then just run the white wire to d14 and check closed loop disable in hondata.

no that wasnt the one... that link doesnt say anything about D10 or ELD..

in the other thread i participated in they didnt say anything about a switch.. just if i want to datalog hook up the wideband output to the ELD on the ECU and since i wont be running a stock narrowband sensor i need to wire the narrowband output to D14. and thats it. and it will still go into closed loop and you can still disable closed loop while you tune.

 

am i right?

opps my bad. but yeah the hondata website is saying gray wire to d14 and white wire to d10. then you setup the input for the wideband signal in the hondata software to read from the eld. and the eld should no longer be hooked up to the ecu. should be pretty easy. GL

 

You have two options.

Option A:
Run your WB signal to D14. This would be your choice if you run in open loop all the time. If you chose this method, click the Source "O2 Sensor"

Option B:
You run your WB signal to D10 and the narrowband wire to D14. This would be your choice if you plan on running in closed loop. If you chose this method, click the Source as "ELD".

Its only 4 wires max. Its not that challenging.

 

yep i got it all hooked up now.. thanks!

running closed loop with no stock sensor and datalogging. im good to go!

yea i know! it disappeared! lol

i know we finally figured out how to do it.. but i just got around to actually wiring it up to the ecu and forgot how it went and then i couldnt find the thread
