    In my test (FR), VehicleSpeed is virtually equal tot front wheel speed. No clue hoe corr. speed is calculated.

    Could you confirm that rear wheel speed < vehicle speed on acceleration?

    On FWD cars : actually, RWspeed = Vpeed, it's FWspeed > Vspeed on lower speeds (when acceleration is higher). But close to top speed (when the acceleration is slow / null), RWspeed = Vpeed again, but FWspeed < Vspeed.

    On a RWD, the phenomenon is inverted (FWspeed <> RWspeed).

    Didn't tried out 4WD cars, but it may be interesting to see how it behaves with 50-50 ratio and something more like 70-30.

    I think Corrected Speed is measured via some vector mathematics based on the position of the car along the length of the track against a function of time. You can probably find out exactly how CorrSpeed is measured in the help files, no?

    Of course, forgot to check that, my bad. This is what the manual says about Corrected Speed :

    Still somewhat foggy, but at least we know what parameters it takes into account, and that it seems irrelevant for GT6.

    Hi, sorry for bumping, but i started an analysis of the different tire compounds with MoTeC i2, please see here. :)
    There is something puzzling about the wheel speeds, tough... :odd:

    Hi Guys!

    I tried to export my 7 lap roadster TC race to motec but it show only a one long 16min lap.

    How can I fix it?

    Edit. This trac is Red bull ring full

    You can choose when you want to split the lap acquisition. I don't remember which option I used, but you can.

    There are two files exported, ending in .ld and .ldx . The .ldx file contains the lap beacons, and motec should import them and split the logged data into multiple laps. If you don't have the .ldx file, you can insert beacons in the lap editor but it's more comfortable and accurate to use the exported beacons.

    I'm glad this thread received some attention on the front page of GTPlanet... The MoTeC software can do some seriously awesome analysis. :tup:

    As @danbojte & @TurnLeft said "Congrats for the Thread of the Week :tup:"

    That's really a lot of info to digest!

    I really need to start doing this. So I have a few questions;
    Where on MoTeC's site do I download the Analyzer?
    Does the Analyzer work offline or do I need to be connected to the internet?
    Will the program run on Windows XP?
    Any help would be greatly appreciated!
    Cheers!

    Thanks! I greatly appreciate it! Now I just have to wait till I get home tonight and see if I can install it on my 17 year old Desktop.
    (In case your wondering, it still works because it was only connected to the internet once!)

    Not sure what the sys req is, but if it worked on my old computer it should work on most.

    Well my desktop wouldn't work because it needed the service pack 3. I only had service pack 2, and I wasn't risking hooking it up to the internet. So I got out an old laptop, and got it working. HOLY CRAP Theres a lot of stuff. It's going to take me some time to figure it out!:lol:
