+1^ I usually start logging about 2500 rpms then WOT to redline and cut the log right after I cut the gas seems to work fine for me.

Goto Start -> Control Panel -> Region and Language -> Make sure its set on English (United States) and see if that helps.

Hi Jonmorera,
I tried it in virtual Dyno for you, and I tried your log in EvoScan v2.9 beta… not so great pile of knock sum 13 you have at the end there, even though it’s quite rich in fuel, do you have a boost sensor you can log also?

Oops I just noticed EvoScan beta v2.9 has the HP and Torque @rpm around the wrong sides. I better fix that.

Couple of things I noticed… In EvoScan I had to set drag co-efficient all the way to 0.5 to make the same hp as VD1.1.4 which only has a drag co-efficient of 0.38… I’m guessing my horsepower calculations work slightly differently than virtual dynos. I might have to reprogram my hp calculations a bit to match up? any ideas Brad?

evonewb, EvoScan v2.9beta can import files, and will split out all the Power Runs without having to edit the csv files first. And can display power graphs as you are driving in realtime. Brad, perhaps Virtual Dyno could find multiple runs in a single csv file too? so that we don't have to edit them in excel all the time first?

Brad you could program it so that those countries that use commas as decimal seperators will still work without changing their regional settings. I programmed into EvoScan a few years ago to replace all commas with decimal points. that way .net can process the calculations correctly.

I noticed in Virtual Dyno even with boost/afr smoothing turned off, I still couldn't see the real 13.2 AFR reading @ 4125rpm that I could see in EvoScan … might be still some form of spline chart series smoothing Brad? can you turn that off?
