    Default Logging Review

    It's not wide band tuned so I just would like an extra set of eyes on this. Is this log showing everything to be nice-nice? Crazy knock parts aside.

    what type of tune are you running?

    after filtering and deleting cells without enough samples the resulting ltftben looks like you might want to keep working on getting the fueling a little closer. also fyi with all the filters on i had all the kr disappear.

    log maf frequency next time. unless you like them i would not log system voltage, pulse widths, delivered torque, and anything else you can live without so you get a better sample rate

    do you have a wideband?

    DANG IT GREG!!! lol...just when I think I know what I'm doing you introduce something I'm not aware of. Ok, so what is this 'filter' you are talking about. How does it work? I know my knock existed bc I had some wacky PE Mode Commands. Any particular area of the log looks really off?

    I do not have a wide band set up yet. It is planned later this year when i get a new exhaust made. I already logged, mapped and adjusted the MAF Frequency.

    On the Maps tab, click the Edit Filter Settings button, and open an existing filter, observe the include/exclude conditions;

    also, the scantool user manual discusses filters.

    what worries me the most is seeing that you have ltfts ranging from -16 all the way up to +10. To me this indicates that something is wrong in the fueling dept. It will be much easier for you to get it dialed in once you have a wideband. Also remember that you can only tune part throttle with nb o2 sensors.

    these are the settings i used for the quick look at your tune:
