Wideband Question (EFI Live Related)

Wideband Question (EFI Live Related) I currently purchased a Zeitronix Wideband controller for my car. I have it all installed and such, but am trying to incorporate it into EFI Live. Here is my problem. The output I see comming from the controller doesn't line up with what there website and instructions say. Here is a graph from there site.
According to EFI Live, the output I am seeing will vary from 1.7-2.4 volts for a a/f ratio of 11.2-11.5 (according to the zeitronix datalogger). I tried to use the PID that is posted on here and EFI's website, but it won't even come close. I get a reading on EFI live with that pid of about 21:1 LOL. Anyone have any ideas? I tried to email Zeitronix but haven't heard back and there is no phone number for them. Thanks in advance.

You may want to hang tight for a bit and get their upcoming Flashscan interface and the V7 software, as it will integrate the wide-band data right into the logged stream and look like just another PID that is 'internal' to the software.

So you're stuffing the voltage to the A/C pressure sender.
Are you then pulling a raw voltage PID, or some pressure
value transformed from that voltage? I think you need to
determine whether you're getting the straight value or
something else in your data stream, before you can
trust the subsequent conversion function's results.

Version of EFI Live is the newest Pro version.

Is the conversion factor and PID different for the LM-1 compared to the Zeitronix as the conversion factor for that it is (RAW({GM.ACP})/5.1)-correction factor ?? LINK

That link is telling you something different. Why don't
you try raw()/51 to get a 0-5 value and go from there?
Verify that you do get values in that range and then
try them out with the transfer function.

IE.. If the GM.ACP shows a value of 130 (dataloger shows 11.5 a/f at this value), divided by 51, that equals 2.5. According to there site and ****, 2.5v is 14.7...

In EFILive you have to Record (red button) the data logging for the CalPID to work. If I connect and start monitoring (yellow button) a set of PIDs the WB data will be incorrect.
What is the current voltage output range is your WB?
If you would like you can email me your EFILive log file and I will take a look at it.

(RAW{GM.ACP}), I think..

PM me your email address and I will send you my calc_pids.txt file.
You also need to know for fact what the output voltage of the WB controller is.

Addy is black02ss@ls2.com
I am still waiting on the voltage output. Like I have mentioned, there website says 0-5v but the graph above shows 0-3.5v. I am stumped.
I will be on AIM in about 30mins if you are around man. I would like to pick your brain on it if possible.
Thanks for the help guys.

You need to find out if the WB output voltage is linear. If it is not then it will be hard to record a meaningful value into you tuning tool. You will have to post process the data in Excel.
It looks to me like the range is as follows:
10:1=0.4v
14.7:1=2.5v
20:1=3.1v
It looks to me like the range is as follows:
10:1=0.4v
14.7:1=2.5v
20:1=3.1v
