    Filters

    I have a question concerning filters, It appears my ALDLdroid csv files have some weird formatting errors for certain parameters. For instance the "error 44" column seems to indicate the power enrichment state, and "error 45" appears to be AE MAP, and the "O2 sensor rich" column seems to be AE TPS. If i wanted to filter out all the data where "power enrichment" is active I would think I should select "error 44" for the filter but when PE is active it shows "Power" in the .csv file so what do i set the filter operation as? should it be true, false or something else? the log file is attached. Thanks for the great work on this tool it is a great help!

    here is the dictionary file, you can see all the viable true/false values allowed.

    you can edit your adx file that aldldroid uses to change the value. or you can copy the dictionary.txt to the same directory that your trimalyzer.exe is, and edit it carefully to add 'power' or whatever to the true line.

    be careful editing it, it has to be perfect, it's not really checked for errors so it will probably just crash if you add anything odd.

    Perfect! that did the trick, thanks. One observation I've made and I'm not sure if you intended it to be this way or not but, Every time you press "redefine input" and then go back and reprocess the log. The parser log does not reset, under "filtering" it just keeps counting up. This caused me some confusion when i noticed the # of discarded records exceeded the total number in the log.log.JPG

    Here are some pictures comparing Tirmalyzer with my spreadsheet using the same filters.

    EDIT: This is with an ALDLDroid log using $E6 mask. Added the log I used.

    thanks very much for that detail. the data looks pretty decent

    does your spreadsheet use integrator data? to make the comparison for error checking you might have to disable it. the new version will have a toggle for it. otherwise looks pretty good.

    also feel free to play with the hystersis values in advanced settings to tune "loose cell" mode

    oh and the wb data is likely quite different due to the 'minimum records' setting in advanced

    it writes off a cell as junk based on trim behavior so might have to lower it when analyzing small wideband data sets

    0.9 BETA:
    - some code cleanup and general optimization
    - ammended dictionary
    - fixed bug where filter statistics were not reset
    - ignore integrator in arbitrary input mode
    - add option to more easily ignore integrator
    - add option to use leanest trim in dual bank configs

    .... you should know where to get it by now

    No my spreadsheet doesn't use Integrator data. I hadn't thought about the integrator. I ran the log again with the integrator disabled and got the exact same numbers in all three modes as if the integrator was enabled. Another bug maybe?

    I'm still impressed with the data. The data presented is after using Trimalyzer to tune my ve's with the "Geometric" method. I also used it to adjust my PE AFR (WBO2), and the output on the dash gauge is more in line with your tool than my spreadsheet. Go figure.

    my tool uses the integrator data but not in its entirety, it just skews the blm value with it slightly to get pre-learning and inter-blm-cell type data. this is done with a reduction multiplier, it's in advanced settings. TUNE_INTEGRATOR_REDUCTION. by default 38%

    Heres my results from my log done today. Im now on my 5th run through your program. Started out extremely rich and now its definitely not as bad. Does it look as though its leaning too much?Attachment 11597

    Ran it through with a new log and seemed to help a bit..Overall worked perfectly to get the table very close and quick. I think i just need to fine tune now. Was it loose or strict that would be more helpful in that case?Trim#6.PNG

    yeah it's definitely pretty good! remember that 132 is only a 3% fueling error, which is really nothing, it's just running at nearly 15:1 instead of 14.7:1, and that's just until your trims take effect. totally safe unless under really heavy load.

    loose should be ideal even for fine tuning. by 'loose' it just means that samples close to the border are averaged into both cells. it's not spreading the data around very much. you can tighten the boundaries on map and rpm hysteresis (go a bit lower). i think there's no reason to use 'strict', rather just see you tune 'loose' until it behaves for you...

    i wonder if at this point not using the integrator might help it get closer too. some configurations have a stable integrator and some don't.

    edit: since obviously the shape of the table is pretty good, maybe just *0.98 the whole table in tunerpro and see where that gets you.
