So i've followed all the rules via hondatas setup procedure. I'm using the D10 ELD input...hooked up the power to the fuse box and ground by the ecu. I disabled the o2 heater. Have the hondata set at 0 voltage offset and the lambda at 0, 10 and 5,20 . Just like hondata says.


The PROBLEM though is that when i datalog, it says like 19:1 for an a/f when my wideband gauge is reading like 14.9:1 at idle.

How do I fix this? Where could the problem be?

Thanks for any help.

 

Did you remove the R136 and R138 components to be able to datalog via eld ?

 

Where are r136 and 138 at? I must have missed that somewhere.

The hondata help file tells you to remove these for eld datalogging.

The resistors are located on the side of the ecu near the ecu plugs.
Be careful when you cut these out as they are labeled a little funny.

 

Do you have any pictures showing exactly what, where, and how to cut them? I'd really like to not mess this up. haha. Thanks for the help too. I'm sure this sounds like my problem. Cause everything else is setup right.

 

This may help.

In the lovely fuschia is is the letter "D" corresponding to the ECU harness plug it is next too. Resistor in the middle is R137 and is NOT TOUCHED.

Oh yeah, you don't have to desolder them, just cut them off.

 

Ok cool...I just cut r136 and r138. It def changed the value, but now ....


Wideband gauge says = 13.7:1

Hondata says = 12.9:1


Now whats the problem??

 

i would disconnect it from hondata so its just reading off the PLX, get an idea of what it reads, then reconnect it make sure the PLX reads the same it did before you reconnected it. Then adjust the voltage offset in the software until they read the same.... Thats what i would do, someone else may chime in with a better response

 

I keep reading it off my PLX gauge...then I hook into datalogging to see what it reads. Seems like no matter how much I change the voltage offset they never want to match up and keep changing.


What is the third set of boxes supposed to read for the voltage and lambda settings? First box i have 0,10 ....second box is 5,20...what goes in the third box?

 

Might be a silly question, but for the resistors for the wires going into the ecu, I soldered one end of the wire to one end of the resistor and the other wire to the other end. Is this how your supposed to properly do it? Just wondering if maybe thats throwing my numbers off?

 

I dont recall installing any resistors inline with the wiring, that would for sure throw things off, the PLX unit came with the noise filters if i remember right and i didnt even install those...

You may also want to try and reground the PLX unit itself, relocate it at or near the the ECU ground...

You may want to start asking questions on the hondata forum, those guys are pretty sharp, i had some of the exact same issues that youre having and i ended up going with an innovative wideband.... never got it sorted out as good as i wanted to....the innovative is a much better peice IMO and its cheaper!!

 

Sorry, I was referring to the noise filters. I believe i have the power for the unti in the wrong spot to use if with the hondata...and i'm going to reground just incase. I have the unit off the cigarette lighter which i just read it says to only use if your only using the unit without the hondata. So i'll try going right off the fuse box like they say and getting a better ground. Hopefully this solves the issues. This is my second plx and i love it. The actual unit works great. Just having troubles with syncing it up to the hondata.

 

So I just switched the power and ground. Power to the fuse box and ground directly to the battery. Still no difference. Only other thing i can think of is the noise filters??

 

For the record....


The power from the cigarette lighter is fine...the ground i had was fine. I took the noise filters out and everything matched right up. I used the 0,10 and 5,20 5,20 and an offset voltage of just -.04 and its exactly identical all the time. Hope this thread helps someone else. Thanks for all your help guys.

 

Good deal, thanks for reporting

Sorry, I just got your IM. Wish you would have said that I would have told you to remove those damn things. They aren't needed....at least I haven't seen a time when they were needed. Glad you have it worked out!
