ECMlink List of Values to Log

[snowborder714]

It seems when people post up and ask for log help, there are always some values that are helpful to look at missing from their captured values list. Here's a list of values that you should have captured to make answering tuning questions quicker/easier.

If you're running SD, there will be some other values you'll want/need to log. These are noted below.

Please make sure to rename your wideband and MAP something easy to find (i.e. "Wideband" and "MAP"). This way we aren't searching for LinWB or something odd that auto-populates. Using the recommended names will also make it easier when importing into tuning programs/spreadsheets such as LinkTools.


Ideally you should just log all of these values all of the time. Just figured I'd break it down in case anyone wanted to know what values to look at for certain types of tuning.
