It appears I need to run this adx file: S_AUJP v5 2030_D_2-WBo2 Innovate LC-1 and it appears the formula is setup correctly for the LM-2 with 0-5 volts and 0V = 7.35 AFR and 5V = 22.39 AFR.
Now looking at the S_AUJP bin it shows other WB options but not the LM2 and the LC1 option shows here but it shows 1 to 2 volts not 0 to 5 Volts. So I assume this will not work and another option should work like the AEM appears to be the same voltage range the there is the Raw data option.
I’ll take a look when I get home…
I know I ran into issues trying to set up my AEM WB and ended up having to go through some customization with a lot of help from one of our resident gurus, 84Elky.
And then after that, I had to fine tune the conversion formula a little.
Meantime, you can take a look and see in this link… My stuff is toward the middle-end of the thread along with the resolution.
I did find your post in my research, looks like raw data is the way to go and my formula should be (X * 0.05875) + 7.350000 per EagleMark over at gearhead-efi.com. I should be getting the pins for the ECM tomorrow, but am going on a fall cruise tomorrow morning for the weekend so I will not get to this until Sunday night or later. I just wanted to get everything all setup and ready to go.
Good news bad news, good news is the terminals came in the mail today and I started wiring up the output cable then when i put the terminal in the connector it did not click in and would not stay in the connector. Turns out they sent me LT1 style pins instead of TPI.
I have the ECM pinned to F14 from the LM2 but not getting any WB readings. I have the Raw output flag set and the Input pin flag not set so it reads pin F14 in S_AUJP bin. Then I Edited the definition in to the below settings:
Does this all look correct? I logged it and got nothing from it.
Also I just connected the ground to the chassis next to ECM along with other grounds using red wire from from output cable and white wire to pin F14. I'll test the output and change to engine ground if needed.
Are you sure you're actually getting an output from the O2 sensor on the 0-5V output? Verified with a DMM?
To test the ECM side of the set up, simply get a 1.5V battery and tie the negative end to chassis ground and then the postive end going into pin F14. You should see an AFR readout being generated...
Do you think I need spaces in my equation? I have it without any so this with spaces: (X * 0.05875) + 7.350000, or this without:
(X *0.05875)+7.350000.
Did not matter it is not seeing the WB and I verified out put and it was showing 5 Volts at 20.8 A/F and 2.7 Volts at 15.7. I adjusted the equation and it changes but it's not change as the A/F change. I added a ground for testing to the ECM ground also. It is acting like the ECM is not seeing this.

Reason: spelling
I can try pin A3 tonight after work. Here is a shot of the data in list view. It was showing 7.xx A/F so I added to the equation to get it to match the key on 20.85 A/F but no change when I started it with a different reading.
Nothing reporting on A3 either. I also tried it with pin set and not on each one as well as another ECM. Maybe this formula is incorrect? I am getting 9.70 for a reading with this equation (X * 0.05875) + 7.35000.
Why would my formula be any different from another if it is a simple linear 1-5 volt reference?

Reason: Added files
Can you send me your adx file? I'll run it on mine and see if the ECM picks up the O2 readout. If it works on mine, then it's something up with your hardware setup.
Have you tried having one of the gauges show the raw A/D data? i.e., WB (Raw Data)?
That would at least tell you if the ECM is even seeing the input from the WB. If it is, then it's something in how you set up the coversion for the WB (Gauge).
I set the raw data a/d output in the bin but nothing specific for the gauge in the bin that I can see. I then setup the adx and see raw data (gauge) in the Values list of the ADX and just adjusted this and tried it, but I do not see this specific as a PID showing as raw data gauge I do see WB AFR gauge and this adjusted with my equation but also did not follow the actual A/F gauge when running, both now show 9.70 A/F now.
I just loaded the bin F14 bin, the XDF and the ADX file in that zip file you posted. Car started up just fine. But I didn't get any output on the WB either whatsover. Granted I'm running an AEM, but I would imagine that TP should be reacting to some sort of voltage input.
This seems to point to some issue with one of those three files and not your hardware set up...
BTW, I found that your pin F14 bin actually had the box checked for A3. So I corrected it before running.
Thank you for trying! I was just looking at these screen shots and I am editing the WB option at the top of the list in the editor. Your screen shot shows your at the gauge option at the bottom of this list and there is a raw data option here.
And:
It appears it was already set up OK but does it matter which choice here? I will try to test tonight.
Ok, it's your bin file that's the issue. When I run my bin on your adx and xdf files, I get responses at the WB gauges. Granted the values are incorrect, but the ECM sees it and is reporting through TP.
Only thing is, I don't know what is wrong with your bin....
Found that your bin also didn't have WB OPT 2, b0 set either for RAW A/D Output. I set that flag as well, but still didn't make a difference. It's not until I run my bin with your adx and xdf files that TP starts reporting WB AFR output.
Just e-mailed you my bin.... recommend loading on to your chip to verify you get the same results as me (WB values will be off, of course, just verify that TP actually sees the WB. Change one of your adx gauges to show the WB (raw data) as well. Just need to idle a few seconds and watch the TP WB gauges.
If that works, then recommend doing a compare to see what's different in terms of the option bits or other things...
Your bin works! Added the WB gauge and WB raw data and these were the same reading as my LM2 controller. My LM2 gauge I had added works also but like you said would be off and it was reading around 22 A/F compared to 15 A/F.
So your equation matches my LM2 controller which I figured most WB controllers would have the 1-5 V out put as this is the working range of a wide band. I will try to go through and compare bins and see what is different.
A correction here I had stated "My LM2 gauge I had added works also but like you said would be off and it was reading around 22 A/F compared to 15 A/F." This LM2 PID was actually accurate, it was PID: WB AFR (LC-1 1-2V) that was off at one point showing 21.20 A/F when actual was 13.93 A/F.

This helps thank you for the screen shots.
