Pcmlogger EGR/WB profile

They go by many names, P01, P59, VPW, '0411 etc . Circa 1999 to 2006. All VPW OBD2 PCMs.

114B is the correct PID, I use mine for fuel pressure.

edit: equation to get to volts should be x / 51.

I've started doing this, but there are still a few that I haven't determined what they are.


These are all for OSID 12587603

Pin 64-green is for the fuel tank pressure signal. I will look for the pid number. It is $114e. Check if the os support it, if not a simple patch will fix it.

Thank you!
Moved wires to Pin 64-green and Pin 23 Blue (gnd) and with this results are really close to cauge:
Code: Select all
    <Parameter Name="AEM AFR" DefineBy="Pid" ByteCount="1" Address="0x114E">
      <Conversion Name="AFR" Expression="(x/21.473)+7.3125" />
    </Parameter>

with Aem X-series WB. (my Innovate didn't survive from firmware update)
Conversion is from Aem installation manual + aaronc7 message: "volts should be x / 51"

Now looking pids for knock retard (11A6 ?) and injector duty cycle (12C3 & 12C4 ? 1468?) but maybe it is another story.
Edit: Knock retard is already defined

KR 11a6 (22.5*a)/256
125a Inj Pulse Width bank 1 ((a*256)+b)/66.56
125b bank 2 same formula.

IDC is IPW*RPM/1200

:shock:

That's correct. 125b bank 2 will be the same.
ASpark is a good one to see which table HO or LO spark is biasing FC30 ((A*256)+B)/4096

This gives only error: "Logging interrupted. Unknown identifier 'a' (at index 2)."
If I change to Expression="x", value is always 0.0

The "A" and "B" variable thing is commonly used in torque and similar obd apps. Let me say up front I haven't actually used PCM logged yet, but it seems to just use X as the variable.

I have Injector pw (125A/125B) as X/65.535, result in milliseconds. X is a 2 byte response for this PID, it looks like pcm logger will handle it just fine as is.

With my current logging profile query time is ~125ms.
I tested with smaller profile, and reduced query time to ~80ms
But now I get lot of timeouts. is this normal ? Something wrong with profile?

Code: Select all

<LogProfile xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

    </Parameter>
    <Parameter Name="Mass Air Flow" DefineBy="Pid" ByteCount="2" Address="0x10">
      <Conversion Name="g/s" Expression="x/100" />
    </Parameter>
    <Parameter Name="Knock Retard" DefineBy="Pid" ByteCount="1" Address="0x11A6">

Not sure on the time outs. I've used PCM logger, but have not tried with any profile other than what was already on there. What adapter are you using? I have my aem x series as (volts*2.375)+7.3125, is yours working correctly?
