Custom PID not working - help please!

[reactor2]

When I scan in the built in PID 6001 (commanded AFR high res) it shows it in the scanner just fine...it works. However, if I create a custom PID (i.e. test) and set the function to [PID.6001], when I start the scan HPTuners tells me <unsupported parameter>. What am I doing wrong?

[reactor2]

It looks like "Air Fuel Ratio Commanded Lo Res" ([PID.6000]) and "Air Fuel Ratio Commanded Hi Res" ([PID.6001]) are just not supportd in HPTuners. Are there any substitutes for these PIDs?

[reactor2]

Figured it out. For the above to work I needed to include "Air Fuel Ratio Commanded Hi Res" in the table BEFORE I used in the custom PID....not sure why that is, but it is what it is.

I am having the exact same issue but I'm not sure what you mean by:

'For the above to work I needed to include "Air Fuel Ratio Commanded Hi Res" in the table BEFORE I used in the custom PID'

Can you expand on how you got this to work? Thanks!

I just figured it out. I was looking for the pid for "Air Fuel Ratio Commanded Hi Res" in the wrong area. To fix this:

1. Find an empty table cell in the table display
2. Right click
3. Click "Insert"
4. In the "Insert PIDs" box that pops up, expand "Fuel System"
5. Double click "Air Fuel Ratio Commanded Hi Res (afr)"

Now you should be able to create a "Commanded Lambda" user defined entry in the table and it will no longer display "<unsupported parameter>"

Thanks reactor2 for getting me on the right track.

I wonder if there is a way to add this to the Generation 4 section too, I have a 2010 L99 Camaro and had little luck digging this up in that sub group. It wasn't until I did a full forum search that I found this entry.

To simplify for future readers, The rule is: Anything you wish to have show up in any display must be listed in the table.

If a PID is listed in the display and shows on the table but will not read anything other than zero, what could be the issue?

If the PID doesn't blank out, saying "unsupported" when you start scanning, then it's addressing that PID and getting a 0 value from it. What PID are you talking about?

The PID is not blanking out. O2mv and injector pulse..
