logging with serial plx wide band / e40 ecm cos 2 bar system

Hi , very new to efi live plenty of reading to do. I have purchased the new plx gen 4 wide band and will be doing the internal mod https://forum.efilive.com/showthread...R-Serial/page4 and set up my pids but I cannot find the ben pid for the wide band ( plx serial ) I am going to use please help. As this is my first post I have
attached my current pid selection , it has a x next to it let me know what you think thanks kindly.

The serial comms pids are these:
- EXT.WO2LAM1
- EXT.WO2EQR1
- EXT.WO2AFR1
- EXT.WO2ST1
- CALC.BEN1

thanks Joecar.

Hi joe , I want to use the sae.lambda and EXT.w02lambda1 pid but I don't see the CALC. ben pid for lambda ?

You will need the pid CALC.WO2BEN from this calc_pids.txt.


( if your calc_pids.txt is original/un-modified, you can just copy the attached calc_pids.txt to the User Configuration folder )

edit:
in the attached cacl_pids.txt you will have to edit CLC-00-110 to use SAE.LAMBDA instead of GM.EQIVRATIO...

i.e. replace this:

Code:

---

*CLC-00-110
factor            0.5          1.5      .4  "{GM.EQIVRATIO}*{EXT.WO2LAM1}"

---

with this:

Code:

---

*CLC-00-110
factor            0.5          1.5      .4  "{EXT.WO2LAM1}/{SAE.LAMBDA}"

---

Question: which of these pids does your PCM support: SAE.LAMBDA or GM.EQIVRATIO...?

Log each one and post the log.

Hi Joe , im trying to validate my pids (22) of them but the GM.EQIVRATIO,GM.IBPW1,GM.IBPW2,AND GM.DYNCYLAIR PIDS WILL NOT VALIDATE they have an x next to them ?

did a log and believe it logs the sae. lambda which is the EQ ratio . this log was mostly at idle. im using the laptop and
V2 . Also when you log through BBL how do you look at the log with V7.5 scan

Ok, this is one of those special cases...

if SAE.LAMBDA behaves like EQR, then use SAE.LAMBDA in place of GM.EQIVRATIO...

i.e. like this:

Code:

---

*CLC-00-110
factor            0.5          1.5      .4  "{SAE.LAMBDA}*{EXT.WO2LAM1}"

---

( be sure to multiply by it )

Joe , in my user config folder I have two calc_pids.txt documents . I may of copied one from the forum and placed it in my folder .With
the calc_pids.txt e40 file. Do you only need the one and make changes to it ? I have attached both let me know which one to use thanks.

Delete the first file (cal_pids.txt), and rename the second file to calc_pids.txt.

Thanks , again .

No worries.
