EFIDynoTuning Forum

I am looking for some software, to import csv files and allows one to graph and compare parameters against each other. Need to support 100's of parameters at the same time.
My main focus is work related stuff with Cummins Insite datalogs. I also do car stuff as well so I need something customizable to be able to use it with the many different ways that the .csv files are set up.
I have looked at efi analytics, but it isn't geared towards the amount of parameters I am looking at. It does look nice for basic automotive datalogs.
If I get better at Excel I guess I could make a template or macro to feed the log into and it puts it into a nice format for me. Having to do it manually for every file is not time efficient.

Right now I am considering some online courses to get better at Excel and to manipulate the data how i see fit but I would rather focus on other things right now. I do see learning more about excel to be a great skill set to have now days.

I've been using MegalogViewer HD for quite a while. It's a pretty solid option for most tuning fanatics.

I use GEMS data analysis pro to do exactly what you're trying to do. The free version doesn't allow CSV import, but you can get a feel for the interface. I've used it with a ton of calculated math channels, datalogs as big as a 1gb, and with 50+ data sets open before. (Was using it for test data at work)

Im curious, what is the benefit to being able to graph it and compare etc...

what are you trying to do exactly?

It has been a while since I have had a chance to come on here. I apologize for serious delays in responding.

Thanks for the recommendation blacksaleen. It looks great.

Decipha,
Reason I like to graph things is that is the way I work at er.....work and am used to nice pretty pictures and lines and such. I like to see how things trend and react. I have a hard time visualizing things by just looking at the numbers. This wasn't just
about performance oriented stuff. I work on trucks and buses for a living and use multiple different manufacturers software. For fun when I have time I mess with hp tuner, tuner pro, etc ..

Most of the software I use will export a datalog file into .csv. I set things up manually and graph certain sensors out over time to be able to find problems such as sensor readings dropping out intermittently or temperature trends , rpms vs switch reading, etc...
With tunerpro, I haven't worked very much with data logging. I don't have really anything to comment or complain about it at this time. This last week was the first time in a long time I have messed with eec v stuff.

Yeah tunerpro is far more powerful. You simply log it and look at the histogram and tunerpro gives you the corrections. No need in looking at a graph unless like you said your trying to diagnose something.

Tunerpro takes it a step farther though. If anything is out of range it turns red on the dashboard so you can literally have no idea what your doing and know exactly whats wrong.

This weekend, while I was working on finding some information on a question I had for some code for VBA in Excel, I found a very useful piece of software for datalogs.
In my case, I had to clean up the .csv and put it into a format the tool was happy with. Once I did that, it worked wonderful.


It is available on MS store for free. Here is a link in case you guys need something like this.

Here is the website of the author. Looks like he has some other nice tools available that are beyond my pay grade.
