ECUxPlot won't run
Try installing as administrator

ECUxPlot complains about not being able to find main class
Make sure you have at LEAST Java JRE SE 6 . If that doesn't work, try Java JRE SE 7.

I dont see anything!
Turn off the filter (uncheck Options->Filter data).

I turned off the filter. Now it's a huge mess!
Turn on the filter (check Options->Filter data).

With the filter on, I dont see anything!
The filter option searches for a WOT run of a certain length in 3rd gear. If you don't meet that criterion, you won't see any data if you enable the filter. You can adjust the filter parameters in the "Options->Configure filter"  menu.

If you aren't in 3rd (or aren't logging "gear") or aren't WOT (or logging accelerator pedal position), the filter doesn't work that well. You can adjust the filter to look for a different gear in the "Options->Configure filter" menu. If you set gear to 0, the filter will ignore gear entirely. Useful if you are doing multi-gear pulls, or don't always log the same gear.

If your run doesn't start low enough, or isn't long enough (RPM range too short, insufficient samples), the filter won't let any data through.

If you are running into problems, please post your log file here and I will try to help. In some cases, ECUxPlot isn't detecting pedal/gear data properly from the .csv header and requires me to add your .csv format to it.

What is FATS?
FATS is ET from 4200-6500 in 3rd.

My HP estimate is way off
Adjust the numbers in "Vehicle Profiles->Edit Constants"

My flow estimates (compressor map, calc AFR etc.) are way off!
Adjust the numbers in "Vehicle Profiles->Edit Fueling"

The "MAF" parameter is a bit confusing. If you have a non-stock intake set up, the "MAF" parameter is used to set a *correction* to the MAF values calculated by the ECU. If your tune properly calibrates MAF readings for your MAF, you should leave this parameter alone. If, however, your ECU uses underscaled MAF values (you have a larger MAF, but stock MAF maps), you will have to increase the MAF diameter. The correction that ECUxPlot is using is shown in the box right under the MAF parameter so you can check for sanity. Future release will probably only have the correction, not the diameter, since it is increasingly uncommon for people to have improperly scaled MAF numbers.

If you aren't sure, you can calibrate it by hand by comparing Calc AFR with wideband data.

Having some issues with the filter/FATS window. Can't get data to show when filter is changed to 2nd gear. And 3rd gear data looks incorrect. Changed some settings around with no luck. I also noticed in the excel file for the log that its showing 4th and 5th gear being selected at a point in the log, when I know for a fact I skipped from 3rd to 6th. Not sure what this means..   My power levels are also way off. I edited the rpm/mph in constants, and it's even more inflated. Not sure what's going on there either.  Log attached.  Any help would be appreciated.

Works fine for me.  Win7 Ent. 64 bit SP1, JRE 1.7.0_09

Bump. New release. OP and topic updated.

i forgot most of what we talked about except for what i put in the issues area on github...

https://github.com/nyetwurk/ecuxplot/issues

please remind me (preferably by adding it there directly), its been too long

Oh: is there a basic 'operator instruction manual' for ECUxPlot?
From making sure all files are properly installed and in the right place, to how to load the correct files (what format, columns, headers, etc.) and what/how to output. Plus some 'example' files to test the installation.
