Odd glitch polling LTFT's

[mistermike]

Sometimes when polling LTFT's on a 2004 GTO one or both banks will yield identical values for all but a few of the cells, other times I get a normal reading. Also, when I'm getting the identical value thing, the values don't agree with the real time reading. Any thoughts? Noise issue, hardware problem, or do I need an exorcist?

Might be a bug but I'd recommend just using the real time values like you mentioned. They contain much more powerful information.

The LTFT matrix is not updated each time the LTFT change during PCM operation, it's values may lag the real-time LTFT values significantly. However, it does give an overall view of ALL your LTFT values in one screen.

Thanks, Paul. I'm learning slowly but surely. It looks like the maps are the true tool in the final analysis, but it's nice to have the LTFT matrix as a quick reference.
