Cruze data log visualizer first release!

I'm happy to announce that I've completed the first version of the data log reader. For those of you with a Trifecta cable (you don't need a tune), you can now visualize the tdl files (data logs) that EZFlash produces when you do data logging.

FYI: This should work with ANY car that EZFlash can data log so the Sonic logs should work too.

This is version 1 and it is usable. However, it isn't complete. What I'd like from everyone is a cool name and if anyone has anything to contribute, please PM me. Doesn't matter what it is. I'd like to build a wiki to explain what the data points are. Additionally if there are any data points that can be computed by using one or more of the logged data points, please send me the formula so I can add it in.

Right now it only shows english units. I'll be adding a settings section so you can change this to show metric as well. Also, if it crashes, there is no logging yet so just send me your data log file (if you want) and I'll try to see what the problem is and get it fixed. If you would like to see any features, please post them here as well as any comments.

Requirements: You need to have .NET 4.0 installed (Download: Microsoft .NET Framework 4 (Web Installer) - Microsoft Download Center - Download Details).

Update: Version 1.0.4.5
Added print feature. You can now print the chart
Misc. bug and UI fixes

Update: Version 1.0.4.2
Added chart zoom feature
Added Min, Avg, Max line options
Added additional info for data points
Added export to Excel CSV option
Added Grid view
Fixed log version check

Update: Version 1.0.3.8

Bug fix: Now loads all PIDs

Update: Version 1.0.3.7
Added indicators on the data points to indicate if it's an SAE or GM reading
Thickened up the graph lines for better visibility

Will it work on a stock Cruze or did Vince create his own logging format? Nice work in any case.

As long as you have a cable and you can do data logging using EZFlash, then you can visualize it. As far as the file format there is a "custom" format, yes, but the way the data gets written for each frame I believe comes from the cable or ECM since the response from the ECM goes directly to the file stream. I have no idea if the cable does any translation or formatting of the messages to/from the ECM.

Basically, you don't need a tune to use this. You just need a way to get data logging to work with EZFlash. So yes, this will work with a stock Cruze.

Updated, see OP. Had to move it to DropBox due to file size limitations here.

Maybe NOW people can truly mathematically analyze their fuel consumption vs. highway speed(s) for more accurate FE numbers!
I was actually thinking the same thing about other debates we have, like IAT's stock vs res delete. Also, maybe see how spark plug gap affects other aspects.

EZFlash changed the data log format so I'll have to update the code to match. For now use EZFlash 1.5.20 or earlier.

Ok I'm dumb. I saw 1.5.3.0 as 1.5.30.0 (current) so there were actually no data log format changes. But, 1.5.30.0 is adding new data points to the log. I see a few new ones in there.

For some reason, the guys on the sonic forum can't use the app but I don't know why.

For now, you can use the latest EZFlash.

This is really neat. I'll have to look at some logs
Please let me know if it works. I'm getting reports from other car owners (sonics and who knows what else) they just say it failed. But they don't tell me what happened or send me the error log.

Actually, I made an update. Can you just get the latest version 1.0.3.8 and try again? I wasn't loading all of the PIDS for some reason.
