    1998 LS1 PCM data logging

    Are these really just that slow when you data log? I took the 1998 LS1 config file from the repository and in a quarter mile pass I got like 11 data points. Makes it difficult to tune. Anyway to speed this up?

    Yes. The frames per second is listed in the help file for these. Keep it under 24 bytes.
    It doesn't have to be perfect, it just needs to be done in two weeks...

    They are much slower than 99+ PCM's

    However, you are logging more parameters than you really need, many of them redundant. You're using a wideband on a 1/4 mile, so no need to log LTFT, STFT, O2 volts etc. because is WOT only and you need just WB AFR
    You can easily delete half the parameters in the table and dramatically improve the framerate.

    There is something wrong with your wideband, it reads 12.70 all the time. That's impossible.

    Check the modified config attached. You can even delete "Inj Pulse Width"because your injectors seem to be big, so no need to know IDC
