You can also graph COBB logs using Virtual Dyno.

Correct but it's nice to say numbers on the y axis instead of having to probe along the lines.

If you want, post up your log and I'll try to open it on my end... (zip it first and you should be able to attach it I think, otherwise change the extension) Last edited by Zasquatch; 03272012 at 09:27 PM.

The result will be a left hand scale that is in the hundreds due to timing and AFR prior to the pull, but just double click the scale and choose 20+/ as your max and you'll have a nice clean plot. You also will prob need to change line colors... mine came up all pastels...

Right on. Yeah, TPS tells you more, but I log Pedal Position to make sure throttle closures aren't due to me accidentally letting off the gas...

Yup, it makes more sense to use the Pedal to Display WOT runs

Okay. I find it works better for tuning to probe over the line and know the exact data at a certain RPM point. Guessing the data by using the numbers on the y axis isnt something I would do while tuning someones car.

Thanks man.
You can still select a point and see the x and y values... it's a built in feature of Excel

I know. I just have always liked standalone applications over excel worksheets.

As mentioned you can probe the data points with excel when you need to know the exact numbers. however, when you're looking at the overall shape it's nice to roughly know the y values.

Is anyone having issues with the last step of the code, i.e. graph format and axis labels? There seems to be an isolated issue with office 2007 that I cannot replicate for the life of me.
The graph should look like this, widescreen with axis labels for the data you included:

Thanks for this, very helpful.
I think it would be helpful to show a small graph shown underneath (similar to how volume or technical graphs are sometimes shown under stock price graphs) that shows RPM and maybe TPS (or something else), Xaligned with the main graph. This doesn't pollute the scales, and you don't need a high precision graph of RPM.... My 2 cents. Thanks again.
