    More BLM cells in log than the VE table

    I've got my 7427 conversion running, and working. Went to do some BLM tuning. Got home ready to make a new spreadsheet to automatically compute the blms in the future, only to find out that the logging shows the 5's from 25 on up to 95 map, but the bin's table only shows the 5's from 25 to 35, so I have all these extra cells with nowhere to plug them in. What can I do about fixing this? Edit the definition? Hopefully a way to use my current data as well as fix the issue for the future, but if I have to scrap today's data, then oh well.

    How about interpolating teh data and manually adjusting the bin?

    I don't know what you mean by the BLM data "showing 5's". The BLM numbers are trim values that are less than 128 if it is removing fuel, or greater than 128 if it is adding fuel.

    5's as in the MAP reading. The log has map readings of 20,25,30,35,40,45,50,55,60,65,70,75,80,85,90,95,10 0 whereas the actual table to edit in the bin has map readings of 20,25,30,35,40,50,60,70,80,90,100. Due to all the extra cells, I'm not sure how to go about manually adjusting the bin either, as I would think some of the log points I am wanting to use to adjust the table, are showing in a cell that I can't adjust, and there isn't a way(or is there?)to see what each of the data points recorded in order to put the data in the "correct" cell.

    Oh history table... I don't use them.

    Looks like you can just ignore the cells you don't have in your VE table.

    I found the same thing when I started datalogging. I simply edited the ADX to make the history tables match the fuel tables in the XDF.

    Any idea if editing makes it put the 5's blm's in with the 0's, or does it just basically ignore the 5's?

    I'd leave the histogram as is, and just use the cells that are multiples of 10. The middle cells will matching points that are interpolated anyway, and you want the data that is closer to the load points in the bin. But if you wanted you could reconfigure the adx and set it up with the same headings as the bin. You can generate the headings in excel and paste them in, that way when your getting them right you dont have to type them each and every time you change another setting. Saves a lot of typing. (when you change the number of entrys in a row it erases the heading and they need to be re-entered).

    Thanks for all the info guys. Decided to just mod the adx to remove the 5's.
