    I finally got it working with a log from V3 but you have to strip out a lot of stuff and change the headers to exactly match what it's looking for.. with some simple changes from the software creator it could easily use exported logs right out of HPT V3.

    I'm not sure that it's still being developed though? The link in the creators signature no longer works

    played with this tonight and found pretty easy work around to get it working again with HPTuners v3.2.24 and Virtual Dyno v1.3.1

    1) export log from scanner as a .csv
    2) open the export log in Excel (I'm on a mac using 2011 v14.6.5)
    3) edit row 14, column A from "[Channel Information]" to "[Data]"
    4) delete the entire row 15 (do not leave a blank row, delete it entirely)
    5) edit row 16, column A from "Offset" to "Time"
    6) save the file as a 'Windows .csv' file (may not be necessary on a Windows machine)
    7) open the new file in Virtual Dyno

    Far from ideal, but it works and is not very time consuming once you get it down.

    a few notes:
    * sometimes, once Virtual Dyno has decided that a log file is no good, correcting the issue with the log file still results in the same error message. quit Virtual Dyno, reopen and try the corrected log file again.
    * if you have trouble with this method, i'd recommend exporting a Scanner log as a .csv file from Scanner 2.24, as it does work right out of the gate. open it Virtual Dyno to make sure it works. Then open it in Excel and save it as a different name. Make sure that file works as well. This is how I found I had to choose the 'Windows .csv' option. Again, this might not be needed on a Windows machine.

    Thanks Funked, that works perfectly. One more step to check, is that your logged channels match the "columnames.xml" file (open V.D., go to Help -> Open Data Folder. Then open columnnames.xml and scroll down to the HPT section).

    As of 1.31 V.D, open up excel (or notepad) and change/verify:

    Your TPS channel is named "Throttle Position %", and the RPM channel changed to: "Engine RPM (SAE) rpm"

    Edit: I wish you could edit the XML to match your scanner channels, but it reverts any changes made to the file when you open V.D.

    Strange...
    I opened up <columnnames.xml> and in the HPT section:
    • Time is named 'Time'
    • RPM is named 'Engine RPM (SAE) rpm'
    • TPS is named 'Throttle Position (%)'

    On my .csv files exported from Scanner:
    • Time is named 'Time' (after I rename it as part of my 7 step program listed above )
    • RPM is named 'Engine RPM'
    • TPS is named 'Throttle Position'

    ...but it still works like this.

    It must be interpreting the log as some other scanner software log.
    Maybe it looks for hits against any of the software packages listed in the <column names.xml>?
    At the very top of the list, there is a software package named 'Custom'
    You can add names to the 'Custom" package by clicking File > Options in VD and selecting the 'Columns and Profiles' tab.
    Add your names there and save the profile and it will always be in <columnnames.xml> when you start VD and associate those column names.
    As a matter of fact, if you add 'Offset' in the Time box, you can eliminate step 5 from my list above.

    Delete the entire top header so it is just CSV data eg what excel uses.

    Also, although I never saw it stated, I believe you need to restrict the logging to only the parameters you NEED - or at least, to only a few parameters. When I tried with many, it just chokes on that, even though the ones it needs are there...

    Speed
    RPM
    Throttle
    AFR if you wanted/had it
    IAT I also log

    Are the most it needs I think(?)

    Is everyone still having issues with the latest versions of HPtuners and Virtual Dyno? Wondering if they've been resolved.

    I stopped trying, seems too inaccurate to trust it. You need so many controlled conditions you basically need to be on a dyno for it to work anyway.

    I can help get it working guys. I cant check all the forums on a daily basis any more since I have a 18 month old. If you need something the facebook page is a good way to communicate with me about problems or things you need help with.

    To address the accuracy issue I would challenge you to take your car to a dyno and then get a log on the street (like all my other critics) ... and Ill make a believer out of you. As far as I know you can NOT break the laws of physics so Ill bet with you that if you enter the data about your car accurately it will be pretty darn close. Ive got screenshots of a dyno run and a log from the same day showing a 1hp difference on a 701hp Evo. That was from a guy that I converted to VD.

    If you take a log while on the dyno it will not be accurate ... VD factors in HP lost to drag as well given the proper frontal area. The data you have to enter in VD is not really that much. The hardest part is getting the frontal area and drag coefficient which arent that hard considering these days we have google.

    Let me know if I can help get VD working with the newer HPT logs. Ill need an example log so if you can message me on facebook from the page with a log. https://www.facebook.com/VirtualDyno

    The problem I have is logging accurate data, I can't find a road smooth or flat enough. I also get some wheel spin which ruins my data. It isn't a problem so much with your program as it is a problem with getting good consistent data. I found I would get variances of up to 40% on the smoothest road I could find.

    I'm sure with good data I would get an accurate result.

    Yeah my only real complaint was it was a PITA getting the data in the right format for it to work. If we can just export a log and use it in VD it would be really neat to use, assuming you have a flat enough area to use for pulls..

    Brad - I sent you an example of a log from HPT 3.2 (on your facebook page). My email is embedded if you have questions.

    Just an update. Brad told me he needed my log in CSV format (like a dummy, I gave him the HPL format). I exported a log into Excel today and forwarded it to Brad. He said that he will make the modifications to the headers so we can use VD without having to mod our headers.

    Did this ever get implemented? I tried using it a bit ago and it still was giving errors about not being able to find everything that was needed, i.e. time, RPM, throttle position

    schpenxel - I provided Brad with some HPT data so he could make the appropriate header changes needed about a month or two ago. I tested it and gave him some feedback on it. I provided a log I took at the dragstrip, and his software failed. That was my error though. I was unaware that you can only use single gear logs. I have not had the opportunity to test it lately because of weather and free time. If there are fields missing or the software is misbehaving with HPT, the best way to contact Brad is through his FB page.

    I'll shoot him some logs. I suspect that different channels/ECM's are going to have slightly different values in the headers so that may be making this more difficult than it could be. Not 100% sure of that though
