When trying to log a histogram obviously you have to be logging the correct PIDS or said histogram won't even show up when you're logging. Where can I find what pids that need to be monitored for any certain histogram to work? I would assume I'm monitoring all the pids to do it in this case, can't be that complex hahaha
FWIW I'm trying to find VE - AFR error on an 04 cts-v. What pids do I need to be logging? If that histogram won't work with that car, what do I need to do to build one that will?
Thanks
