    Default Engine Oil Pressure PID

    During my upgrade to the Beta BBL that just came out I followed the procedure to upgrade to the latest 7.5 software. I was previously using V7.4.2.

    Then I upgraded to teh V7.5.3 software. I noticed the engine oil pressure pid name has changed in the Scan Tool, and is no longer supported for my controller type.

    I have a 2004 GTO PCM using OS 12587604.

    The PID I was using for Engine Oil Pressure in the 7.4 software was called GM.EOP and I was able to log the oil pressure. In the new V7.5 Scan tool the PID looks like it changed to GM.ENGOILP and is not supported. For me this is a critical PID to log since I road race my car and oil pump starvation is an issue I watch closely.

    Is there anything I can do to log engine oil pressure as I did with the V7.4 software?

    Edit: I just checked the PID description file to see if GM.EOP was available for BBL. I did find EOP in that LS1B_M_PIDs file. I was able to log the parameter in BBL. However when I toggled from metric to imperial units, EOP would remain in kPa even in imperial unit mode.

    You can change the units by specifying the units and conversion factor in the *PCU section at the end of the Options.ini file.

    Here's an example of the entry you would need to convert kPa to psi:

    Code:
    ;   PID      Caption  Prec Units Op    Factor        Offset
    ;   -------- -------- ---- ----- -- ------------- -------------
    PCM,EOP,     OilPsi,     1, psi,  *,     0.1450377377,   0.0
    ...

    Had an oil pump on an ls1 fail on the dyno today efilive would not valadate the oil pressure pid

    So is EOP working again for our LS1-Bs via BB?? We lost it a while ago

    Is there any way to log oil pressure via the Scan Tool software on my laptop? Please see original post for what the issue with that is.

    I'll check the engine oil pressure PID today on an LS1. And post back the results here.

    You should use GM.EOPS to log oil pressure on an LS1 from the PC using the V7.x.x software. EOPS stood for Engine Oil Pressure Sender and originally only returned the sender's 0-5V signal, not kPa or PSI. Now that it is returning kPa and/or PSI in the BBL firmware, its name has been changed to just EOP.

    EFILive automatically changes the BBL PID names back to their V7 equivalents so that you cna view the PIDs in the V7 software. Once V8 software is released the translation will no longer be necessary.

    The Translation table for all PIDs with name changes between V7 and BBL is in the sae_generic.txt file under the section *BBLV7.

    Here is the list to save digging around in the sae_generic.txt file
    Code:
    *BBLV7

    I guess I should be more clear.

    When I open EFILive Scan 7.5 (7.5.4 Build 44) I do not see a PID called GM.EOPS. The only oil related parameters I see are:

    GM.ENGOILP (not supported, and described as Engine Oil Pressure in kPa,PSI)
    GM.OILTS (not supported, and described as Engine Oil Temperature in *C,*F)
    GM.EOILT (not supported, and described as Engine Oil Estimated Temperature in *C, *F)
    GM.EOL (supported, and described as Engine Oil Life in %)



    However, in BBL, I can log EOP.

    Have you tried (re)validating PIDs using the menu option: Info->Validate PIDs.
    If that does not help (probably won't if you are not seeing it at all, even as "non supported"), let me know and I'll dig into this issue deeper.

    Can you please tell me what operating system your LS1 is?
