PHYSICS MoTeC telemetry and dedicated ACC workspace

    Thank you both for your replies. And yes trasgu is very much right, I obviously see that they brake later than me and get on the power at the right times, but I can't see what I want to see to try and improve, it's not like I haven't tried to brake later than I do ahah.
    I am relying on ABS way too much for sure, and TC as well... But I wanted to see how they get on the power (and steer angle and what not) and how to get on and off the brakes.
    Oversteer and understeer graphs from some fast guys would be awesome to see, though that has to do with driving style a lot.

    Obviously I'm not asking to share some world record times or wtv but I wanted to see a dry optimum calm stint of a fast guy and just try and make sense of something. I am really really a begginner at analysing this data (or sim racing lol), but the workspace given with ACC seems pretty helpful already without having to mess with any equations or what not. It would be really cool to see, probably not just to me.

    If there are any telemetry files on the forum I can't seem to find them. The car... Lexus or Ferrari :D though the Audi would be also really interesting to me as I really can't drive it. Any car would be nice.

    @trasgu I really am guilty of many of those mistakes. I will get TC and ABS off the next time I'm able to play (which is in more than a week) so I'm trying to figure out everything I do wrong, which is a lot so.... yeah.... but the more mistakes and bad driving technique that I'm aware of, the better. and for now I am sticking to Spa, I love many other tracks but I after getting all track medals I am focusing on fully learning each track...

    Spa was always one of my fav tracks, though I wish Blancpain ran Hockenheimring

    Before I submit a trouble ticket... Is anyone able to get information on the oversteer channel for the NSX? I get everything else. Also, I don't have this issue with Nissan. I am experiencing the problem at the two tracks I have tried (Paul Ricard and Monza)

    Just noticed this, somehow missed it completely.

    Thanks for implementing MoTeC support and also for getting them to approve of it.
    I loved it in GTR2 and I will definitely make use of it for this one. :)

    Guys, I need your help. The time has come when I can no longer move faster, and I decided to study this program for analysis. My game after installation (as described above) does not record telemetry data. The downloaded data from other users is working properly. And in the system tray, I see this window. I apologize for my bad english. Снимок.PNG

    I have an issue that i cant get motec to create the track map for two laps. It will always only show one map with the first selected lap. but it does not create a 2nd map when i select a 2nd lap by using one of the squared fields behind the laptime. any ideas?

    Hi all, i have the following issue: I set the telemetry laps in setup to 2 and I only getting the export when I leave the session. Mode was practice on nuerburg and drive 4 laps then go to pit. No motec data available. Then drove again 4 laps back to pits still no motec data available. The back to main menu and motec data were stored. Any ideas why if have this behavior? Faced this behaviour more than once.

    I was under the impression that is the default and intended behaviour. You drive your session, end the session and it saves the last n [amount to save that you set in the setup] laps.

    I thought that it stores everytime I leave the pit a file and not only after the session ends. (Session means for me practice or quali. So if I leave the pit 3 times in practice I expect 3 files in the motec folder. Current behaviour creates only 1 file after switching back to main menu.

    Right now it is like you experienced, it is annoying but such is life. When the devs free themselves from the mountain of work they have right now surely they will fix this issue. IRL the teams don't gather the telemetry data once per session, they download the data every time the car comes to the pits, that it is the behaviour that we all expect.

    I'm exactly in the same situation. Cannot get any faster but lines seems to me the same of "others", braking points, the far allowed by the setup and cannot get where and "how" I can be faster. CC just tells me where I do wrong, but no clue on how to improve. So I start looking at telemetry data.
    From solely my own data I can see that I tend to understeer in most of the turns, hence not using all the lateral grip (or speed). But to compare laps with other (fast) guys would be very useful. No any "telemetry data bank" available? We shall open one. Don't' think aliens shall be afraid that newbies will overtake them any soon.

    Regarding the track creation:
    The corresponding data exists already in ACC (e.g. in the AI helper files, if it's the same as in AC). Can't we just use that data to generate the track map?

    trying the Motec I noticed that the ride heights are missing.
    I think it's an important fact because we can't hear if the car touches or not while in reality the pilot can hear.

    I added a maths channel where I would just take my ride height from the setup and substract the suspension travel. Though this results in negative values sometimes, so I'm not sure whats happening there :D

    Struggling to understand how to have the correct track maps loaded and do not have to recreate every time. I tried to rename the file under "Track Maps" folder with the Track name, but not always working (same car on another track do not use the correct one).

    I googled quite a lot, but no luck. Any solution here?

    Excuse me if this has been asked before.
    But how come there's a limit of 30 laps of telemetry?
    In many cases that won't be a full stint. So if you want to get a full perspective, and maybe want to analyze specific moments in a longer race, you really can't.

    And on another note: Personally I feel it's a bit of a clumsy implementation in the game, having to select the amount of laps of telemetry. Every time you enter a new session, you have to remember to enable the telemetry.
    This might just be me, but having a toggle switch for telemetry on/off, that's persistent between sessions, would be preferable, so you don't sit there, wanting to anaylze a stint you just did, just to realise you forgot to enable telemetry.
    - I know there are some pretty obvious drawbacks in terms of clutter, when you just have telemetry files piling up automatically, but maybe an autosave system that only keep data for a limited time, unless you renamed / moved the file, could be a solution to that.

    Those are just some of my thoughts.

    Apart from that I have a question in terms of the API for applications like SimHub, to use.
    Currently it doesn't seem possible to track TC, ABS, MAP-levels(only activation). Also BIAS seem to have gone missing(worked not too long ago, although the data was the raw bias data, and not with the implemented offset to match real life values).
    I suppose all of this 'missing' data is related to what the telemetry is recording in the first place.

    So my question here is: What are the plans(if any) to expand the current API/Telemetry to incorporate data like this?
    @Aristotelis
     
  18. Remember that suspension travel isn't zeroed in the data. For example I ran the Huracan yesterday with the default suspension setup, and while stationary in pit lane the front was showing 13mm of travel with the rear giving 23mm. How negative are your readings going?

    I don't know for certain what is being measured by the 'SUS_TRAVEL' channels, meaning is it damper travel or wheel travel as they will both be different depending on the motion ratio within the suspension setup. @Aristotelis possibly you could shine some light on which it is?

    Also I'm guessing a positive displacement reading translates to compression of the spring?
     
  19. IRL it depends on whether GT3 teams usually run with ride height lasers. Unless a car is designed to accommodate them, with a specific mounting position and hole for the laser, it would require modification which might not be allowed under the homologation regs.

    Assuming 30 laps is a given limit, a solution could be to create a telemetry file at each pit-stop.
