Let me know your diagnosis @Techlet 😂

Sorry to be the bearer of bad news but did you mean to pack 1.91 Lite into the 1.92 zip file?

And I think I'm going crazy with the GT-R GT500 but it's still doing this on my copy of the 1.92 calc (all the other cars I tested before are fine now including the other GT-R race cars!):

The spring values for the GT-R GT500s is still a little strange. In the Lite version, it's loaded in the calculator by default, and shows the below values (which are the same as the other GT500s):

But if I switch to a different car and then switch back to the GT-R, it shows the road car values instead:

And in the Expert calc, it always shows the road car values as above.

Can anyone else corroborate? At this stage it feels like my Excel is just cursed.
 
Good Morning all!

Hope you’re enjoying/making use of the new version. How’s everyone finding the expert gearing calc?

I’m still working on the ARBs, camber and toe setting sheet btw.

Here is what I’ve come up with so far. I think most of this sheet is going to be based on rotation, and stability.

Track type dependant of course. Fast tracks will have less toe, less camber, short technical tracks will have more toe and more camber.

I’m also going to add a selection for tyre wear on or off also.

Just encountered another bug: the Skyline Super Sihoutette is throwing out REF errors in the v1.92 calc.

Hello there :)
I was wondering if it´s possible to get a list of air temperature and track temperature for each weather setting. That would be so nice to have. BY THE WAY: MASSIVE THANKS FOR YOUR WORK: THE CALCULATOR IS SOOOOO HELPFUL!

When you say tune the car? What are you referring to? Do you mean bolting on parts/upgrades?

Like after inputting all the info and the spreadsheet gives you the set up and on each column it tells your changing the value here will make the car more oversteery or understerry etc. The setting from your spreadsheet is good but if I want to make the car more oversteer to help entering a corner with the tooltip then I will know what value to adjust to make teh car oversteery. Hope it make sense lol

Yeah I get what you’re after, I will certainly look at that. This will come back to the sheet I’m working on now with ARBs, camber and toe. Those values in the setting sheet that no one ever looks at.

Also setting your ride height is probably most important. Some rake (higher rear end) is preferable around 10mm. More on some cars…

interesting that you bring up ride height. AFAIK there is a limit on how low you can go but do you have the data in hand (like exactly how long you can go in every car)? To avoid rubbing or the car being set too low im always setting the car sit higher lol

There is a limit on some cars yes. I think you will find that this will due to larger wheels etc, most race cars will go to lowest setting. Only cars that you can fit larger wheels will bottom out…

I don’t have the data no just the knowledge lol

So basically I will just test the cars I drive one by one haha. Gotcha. I drive road cars mainly on GT7 haha.

Rule of thumb, I normally go with wheels 1-2inches bigger than standard, and keep 10mm off the lowest setting for the front height (for flat tracks)
 
Latest update on the Alignment sheet for the tuning calc;

I have completed the Anti Roll Bar Calcs and the camber setup side of things, I am currently working on and testing the toe settings which is proving to be quite tricky! Trying to avoid the rear toe going negative or toe out apart from a FF setup on a technical track. Not quite there yet but shouldn’t be long. Not only that but I have realised that tyre selection changes the values of the max G force so will need to change the layout of this sheet.

Looking at transferring all of the inputs to one sheet. Would anyone be opposed to this new layout? I will also add a tyre selection input to be inline with the new alignment tab. Should I have front and rear tyres separate? So you can select different tyres if needed?

I think having front and rear tyres separate is a good idea.
 
Hold on, I’ve noticed something not quite right in the dyno plot macro. Sorry I need to check something
