When I looked more closely at your formula (and compared it to the NTK user manual pdf) I see it is incorrect...
it should have parenthesis around the subtraction term, like this:
"({EXT.AD1}-0.5)*2.75+9"

Thank you joecar.
The formula works great.
For anyone using the new NTK air /fuel monitor (model 96604) the above formula is what you need!
It's been a while! I am looking for a little trouble shooting help again. I am running a new engine set up now and its been a long time since I have datalogged. I have forgotten most of what I had learned. The issue I am having is getting my afr monitor to read correctly on a log. It used to work perfect. Is there a specific 0-5v input I should be using? I notice my pid (the wideband described in this thread) is under the system Fuel. Should it be under the system WO2-Analog?
The system it is under is a user definable string.
Post your calc_pids.txt file from the folder C:\users\xxxx\documents\EFILive\V7.5\User Configuration.
Here it is.
Ok, it is missing some stuff...
I added in what I thought was missing, see attached (assumes E67 ECM).
Which ECM does you have...?
Edit: correction; and corrected again.
I have the E67
Ok, the pids CALC.NTK_AFX and CALC.BEN_NTK_AFX should work for E67.
I replaced pid txt with your version. I get this when I try to add the pid now. I assume I need to delete the bottom 2 somehow.
Did you select the pid EXT.AD1...?
Did you select the pid CALC.NTK_AFX...?
This is what I see:
