Can someone check my PID???

[MMGT1]

Long story short, I own the program with someone else and upgrading is not an option(eventually going to get it on my own, but for now I'm stuck)

Here it goes:

NGK AFX Wide Band: 9-16 AFR
0v= 9 AFR
5v= 16 AFR

Therefore the range is 7

Does this PID look right to you guys??

[PID.2811]/.5+9

Thanks for lookin',

PID.2811 is EGR position? What is the scaling of that? My truck doesn't have EGR so I've never looked at it.....
for 0-5V then you would need

EDIT:Boy was I off. Did some reading and found some more info. The equation you have works for 9 - 19 AFR. I took the 5V divided by 7AFR and came up with .714

[PID.2811]/.714+9

0V = 9.0 AFR
1V = 10.4 AFR
2V = 11.8 AFR
3V = 13.2 AFR
4V = 14.6 AFR
5V = 16.0 AFR

The EGR is scaled from 0-5v.

Tapping into the EGR with my WB. Using the 0-5v signal so I can see it in the scanner. The PID listed I got from another tread, but it wont read on my scanner.(says its unsupported??) The WB, I hope, I will have by Monday or Tuesday. I was trying to get the "custom PID" functional using the signal from the EGR right now so I know it's working. Then unplugging it and attaching the WB to the output wire. Thanks for the heads up bud, I'll try that one

I think you replied while I was editing. I changed the equation after doing some research. Please look up ^^^^^

Got it, thanks for the help man....

Paul

....and you also helped me to actually understand the PID as well

[MMGT1]

Anyone know what I'm doing wrong here?? I've added the custom pid to the histo as above. Scaning the EGR v in the Table view, chart, and histo. Cannot get a reading in the histo. And is there a way to change how it shows in the chart or table, to show the signal as an AFR? I'm going to hook up the lap top so I can upload my config...

Here's my config

Ok, what you need to do is setup a custom pid so that you can log afr in your histogram.

Thanks bud. I did get this worked out and just submitted it to the repository. Spent most of the day on this, but looks good!
