OBD logging and real-time histogram

[brandonwh64]

I do have a copy of the ADX I started with and the modification I'm at now. I'll post them tonight.

I just searched pid.199e and pid.119 without any hits. Just add all four characters in hex to the string? And that comes back as commanded AFR?

WOW thank you! It sounds like you have done a great job. I am going to setup my tablet for this and test

Ok, I never did get a chance to try out PID 119E tonight (busy being Mr. Mom)...but added some notes to my ADX and attached it here. (Use at your own risk...I'm new to this)

Interestingly enough: my wideband came in and has some options my 2010 AEM doesn't. It has the typical 0-5v output, but also options for 1-2v, 0-1v linear and 0-1v simulated NB.

So I just did a little looking and I'm actually thinking about adding Blue pin 68 to the PCM for o2 sensor #3 and PID22 so I can retain EGR function. I don't have post-car o2 sensors on my 2500hd, so as long as it will read the data, I don't lose any functionality.

Thank you so much! Once I get my car more reliable, I will start getting more involved into this to see if I can help.

So my additons for Target EQ won't work for PID119E or PID68. I get nonsensical data...which seems tied to vehicle speed for some reason. Same with the PID22 for the rear o2 sensor (that I added the wire in). Voltage is 0 at a stand still, and climbs with vehicle speed. Not sure what I'm doing wrong.

My next plan is to change my wideband from 0-1v to 0-5v and try the EGR position wire. But I'll have to flash a new tune to zero out EGR added spark and physically unplug the EGR and tap into the wire. I'm not hugely excited on that idea...but I need something to work.

So from what I am reading, You are trying to log in open loop and trying to get rear O2s to work correct?

It still can be config issue, or the OS doesn`t support afr pid.
What kind of pcm and OS you are trying to log it.

You can try the stnterm.exe to manually log the pid and see if it gets 7f response or it gets actual data.
The elm config through tunerpro is some dark magic for the enlightened.

8322 os on a 411.

Logging in closed loop, but trying to read my wideband via the bank 1 sensor 2 circuit. Target EQ is just to have a reference on what's going on when not in closed loop (warmup, pe, etc.) I have target AFR on my obd1 car and it's handy.

I'll Google stnterm.exe when I get a minute. Thanks

Do you have the stock bin. I will make a list from it, what pids are supported for the OS, so you can log some extra things. There could be even some free 0-5v pins not used by your setup.
