I have wondered the same thing.

Hopefully evoscan v1.0 will address this issue...hey I notice my feedback response was quoted http://www.codeplex.com/EvoScan/Work...orkItemId=1435

too bad i can't vote since i haven't received my activation email yet *3 weeks counting*

vote for the the above feature ^^^

I went back to the first post and added my Data.xml file that corresponds to the logging order in the spreadsheet.

Nice work, just a question: what is the meaning of the value in cell AZ2 (nominal 3500)? Thanks.

Sorry, I forgot to annotate that cell and the one next to it.

AY2: rpm per mph
AZ2: weight of car and driver in lbs

Yep. HP is calculated from the acceleration, and TQ is calculated from the known relationship between HP and torque.

Very sweet calculation man. Question ... is there any way to add an AFR or Boost graph below the HP/TQ graph like most dyno graphs do?

Sure. I'll post a new Excel file in the first post. Give me a few hours.

Oh, one more thing. Sorry. Are these results affected by ambient air temps?

Yes. There is no math in there for weather conditions.
