    Can the scanner tell me if all cylinders are firing the same?

    Guys will the scanner tell me if each cylinder it?s firing the same, or have the same heat? I use a heat gun to measure the heat on each cylinder when searching for a misfire. Would like to use more the scanner for this little issues.

    You'd need EGT probes in each port to know if they are firing all the same heat wise.

    The scanner can log individual misfires for each cylinder on many different computers. Both current and history misfires.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.
