I'm cross posting this from the 350z/Tuning forum. They should really merge these two sub-forums. I haven't had a chance to try this on a vq37vhr but it shouldn't take much to make it work. In any case ...

I wrote some scripts a while ago to help me tune my FI setup. They help with MAF tuning but also provide torque and HP curves to help with tuning timing and provide catalytic converter efficiency parameters to help with troubleshooting. Details can be found in https://my350z.com/forum/tuning/5847...some-data.html.

For anybody interested, I made these scripts available at http://sourceforge.net/projects/balastuningtools/files/.

The actual scripts are pretty small, but I had to include the Cygwin, gnuplot and Perl software that is necessary to run them. That's why the zip file is around 35meg. It runs on Windows and maybe various variants of Unix if you happen to be running that on your laptop.

I chose to leave it a standalone product instead of rewriting it as a web app because it's a street tuning tool and it would probably be more helpful to be able to run it without needing internet access. Also, I just don't have the time for a major rewrite.

 

Links seem bad

 

Thanks. Links fixed. Damn cut and paste.

 

Thanks! Does this work with Utec?

 

It's basically just a log file analyzer. To be useful with UTEC I'd need the format of how it logs data and what sort of tuning tables it uses.
