$OD.adx?

Attached is my VE summary for the 4.xdl file.

My spreadsheet filters the near idle data when the idle flag is active, it also filters out AE, PE, and Open Loop data. TunerPro RT history tables do not filter the data like my spreadsheet.

Overall the tune in rich. One option would be increase the injector flow which will LEAN all VE Cells, both near and off idle. I would increase the injector flow in 1 lb increments, until the VE data showed some rich / some lean BLM's. I would then fix the VE table with the attached spreadsheet.

Do these tools work for any mask or just the TBI masks?

The tools posted can be adapted to other masks by changing the MAP (Kpa) vs. RPM tables to the correct number of cells and values.

The correction factor formula is (BLM Average/128). TunerPro RT history tables can be configured to show BLM averages.

Thanks ill give tjat a try, speaking of that I tried to see what my injector size was but could not make out any numbers or colors other then the orange insulators on the pins. My bin is set for 61 lb/hr as of right now, ill try increasing. Also is o2 data bouncing normal?

Is there one of those spreadsheets for the 7730. I looked on several threads but didn't see any. I smoothed me ve tables and went and datalogger a short trip with ALDLDROID. My BLM is all over the place. Trying to figure out how to make the changes I need.

The attached spreadsheet is what I use for $8D. The spreadsheet IS NOT Microsoft Excel beginning user friendly!

After "crunching" the data log with the Analyzer spreadsheet, I use the $8D VE Fixer spreadsheet.

Pay close attention to 1600 RPM's VE values, they are shared in both lower and upper tables and must match!! Interpolate the 1600 RPM valves not shared in the lower VE table.

The attached Excel spreadsheet will not work with Open Office.

Cant seem to get it to work on my tablet either. Is there a file for it I can download on my tablet and transfer to my computer. I have no internet for my computer.
