Quote from Bob Smith :Go to Tools, LFS Vehicle Data Output Reader

Do we need the copy the info from there or is it automated?
i think you need to put it manually, but where i can get the cog percentages ?
The process is not automated. There was never an expectation of mods, I used this once for the default cars and never looked at it again. You may need to do some maths to get the rest of the values that VHPA needs. Weight distribution is reported directly in LFS though.
Now that there are 100's of cars it's a bit of a chore copying/doing the math for each car

Would be nice if in a future update the bin data could be automatically imported to a new vehicle in the tool for convenience and reduce human error copying
It's a pretty reasonable suggestion, though I'm not sure the bin files contain all the necessary data to accurately create a vehicle. The torque curve, for example, I think we used some acceleration data to work back from. I'm not sure if I'll ever do another update though, and while I'd like to rewrite at some point, time is very much against me.

Can someone explain me how do I make VHPA work with mods?
Quote from ACCAkut :Don't know if anyone cares anymore, but I just got your tool to run on W10 following a related tutorial, copying the files needed from the "additional VB6 components" zip (some W10 will not allow to be copied or overwritten, ignore it) and then registering files one by one until it ran:
https://www.urtech.ca/2017/11/solved-mscomctl-ocx-download-register-64-bit-windows/

Its still a very handy tool to develop cars for other sims Wink

I get the "Component MSCOMCTL.OCX not correctly registered" error on Windows 10. Could you please elaborate on what to do with the file you have linked? (Which folder to place it in).
That file on my machine is located in C:\Windows\SysWOW64
Thanks Bob! I managed to get it to work by following the part on the "additional VB6 components" mentioned on your site under the downloads.
I tried it but as it does not support veh-files I was not sure (as Bob allready said) if it works correctly or at all. So as of today is someone using this marvelous tool and can confirm it is somehow usable with mods if you manually add the data from RAF?
I still used VHPA very regularly, although not with LFS. I'm intending at some point to rewrite it in a modern language and make it far more flexible. I've learned so much about vehicle simulation in the past 15 years! No promises as to when, but the 7 gear restriction, poor electric motor support and rubbish moment of inertia calculations frustrate me when dealing with many of the newer vehicles on the market.

As for LFS mods, if the file formats have not changed then it's just a case of creating .veh files for the mod vehicles. As mentioned in my recent posts here, there's no method in place to automate that; it was a slow, manual process to get them right. I think anyone can do that, so you don't need me. I definitely don't have the time or inclination right now, I've never used a mod in LFS (apart from the ones I wrote myself back in 2007).

Thank you for your anwser Bob. I don`t mind doing it manually even if it takes long. My problem is just that with some parameters I just do not know where to get them. I looked on and off the last days and managed to acquire the most parameters through LFS-Editor or the RAF-File but there are parameters I don´t no how to get them and with some of the parameters I am not sure if I did them correctly.

For example CoG.

In LFS-Editor there are CoG-local-Parameters for my car R=0.004, F=0.06 and U=0.251. I guess it is in meters and in VHPA I have to set the values in % depending on the length of the car. Car length is 4.317 m. So the values are R=49.07% and F=48.61 %. I don´t know if the U-Value can be taken directly as CoG height because there are two further CoG height values (height above ground and minimum height). The result was kind of wrong as you can see the weight destribution in LFS and it differ from VHPA, so I had to "cheat" to get to the same weight destribution. I think the values for rotating and unspung mass may be wrong. In the RAF-File one wheel weighs 16.215 kg, so the rotating mass for rear and front is each 32.43 kg. In LFS-Editor the suspension weighs 80kg, so the unspung mass for rear and front is each 72.43 kg. Or am I allready wrong here?

These parameters here I don´t know where to get from:

Quote :Wheels & Tyres
--------------
Wheel & tyre dimensions & inertia -> Rotating Mass
Wheel Movement & Alignment -> Inclination (is only front/rear) / Camber offset / Wheel:spring motion ratio / Wheel:ARB motion ratio
Wheel positions -> Ride height

Aerodynamics
--------------
Body -> Frontal area / cd / Cl
Aero Devices - > ALL

I get you Bob. I would´nt be also too hyped about supporting a tool that is not up to date with current state of LFS and was made a long time ago.
I hope someone who still uses VHPA now and then can help me out? It is a very powerful tool. I managed to do some setups. I tried to make them completely neutral. I matched nearly every bar to be green. The car behaves mostly neutral but something feels a bit off. So it needs more polishing and I guess the right/missing values.
I think there is not that much left to have a proper vehicle data and then to be able to make setups properly.

After I guess 12 years break from sim racing and especially LFS I started again because of ACE and remembered LFS and tried it ... and now I am all hooked again.
