New Uprev Log Analysis Tool (and it's free)
 

Download the installer here:

https://github.com/kgruesch/LogAnalyze
The installer package includes an instructions pdf.

This is mostly inspired by DJamps online tool, but there were a few features that I felt would help the tuning process, namely being able to run it offline and generating the proper corrections automatically.

The tool is written and compiled in MATLAB, and the installer will install the correct version of MATLAB runtime environment. It's pretty barebones, it basically sorts all your data to the cell that corresponds with where the ECU was running when it generated that data, then plots it in a table for easy viewing.

But it also generates your new MAF curve into a pastable table that you can copy and paste directly back into Uprev. Same with Fuel Comp.

Tables it will display:

• Fuel Comp
• Knock Strength
• Max Logged Ignition Timing
• Average Logged Timing
• Intake Air Temp
• Injector Duty Cycle (Top of color bar indicates max IDC)

Here's some screenshots of the plots:

Bugs:
I've got it working with a few differnt log types, though if your column headers are different from what it's expecting it will throw an error. Don't have support yet for multiple MAF sensors. Still working on that, but it does account for if you're using an LC1 to tune.

Evan is trying to get me some HP Tuners logs so I can add support for the new HPT software (which you should be using instead of Uprev if you can. Evan knows Nissan ROMS better than probably anyone in the country).

Hopefully someone finds this useful.

Will definitely look into using this

Thank you

Thanks 2 you, will be getting this tool and checking it out tonight.
