    Calc_Log_111012.efi Joe, I don't know if you looked at the previous one I posted, but I've logged and posted this one up today so I'd be double sure it was done with your calc_pid settings.

    Hi Rev,

    Did you select the pids CALC.WO2 and CALC.WO2BEN...?

    Note that the pids CALC.AFR_LM11 and CALC.BEN_LC11 are not correct since you programmed your LM-1 to look like an LC-1.

    No it leaves it at 10.00 but changes the 20.00 to 19.99 or 20.01 for some reason.
    Yes, CALC.WO2.lam is the correct pid, it follows your LM-1's programmed analog channels.


    The description should be corrected in that calc_pids.txt file (should not mention "serial" anywhere).

    Hi rev,

    Ah, what I meant by this:

    was this:
    your LM-1 is programmed to look like this:
    - LM-1 channel 2 (V1 EXT.AD1): same as LC-1,
    - LM-1 channel 1 (V1 EXT.AD2): set to constant 2.5V (for purpose of calculating voltage offset);

    so you don't want to use the LM-1 default pids (CALC.AFR_LM11, CALC.BEN_LM11)...

    you want these pids:
    - CALC.WO2 (which has units for V, AFR, LAM, EQR),
    - CALC.WO2BEN (defined in terms of CALC.WO2.lam and GM.EQIVRATIO),
    - GM.EQIVRATIO (see previous point).


    Edit: corrected LM-1 channels.

    4.21667v @20:1 AFR
    Yes, this is how it is programmed. But in the following post, if I understand it correctly, you seem to have them reversed. I take it your calc_pids file is for the above rather than below:

    Sorry if I'm confused, just trying to sort through it all ...

    Ah, yes, sorry, my mistake

    ( please, most certainly question something if it does not make sense )

    I corrected post #24 above to read like this:

    ...
    Yes, correct, the calc_pids.txt file matchs that (EXT.AD1 is the voltage mapped AFR, EXT.AD2 is constant 2.5V).

    Ok, good, thanks. I haven't had time to mess with it all week, but I'll get the all the correct pids selected and hopefully log tomorrow.

    Success! I finally got the correct selection of pids figured out and now my logged AFR is matching my LM-1 display. Thanks for all the help, Joe! I've confirmed that my WOT AFR is swinging wildly lean, so now on to solving that problem. But that will be a topic for a new thread.

    No worries, glad you got it working right


    Remember to save your new calc_pids.txt file some place.
