GT5Calc 2.3b

[GroundedOwl]

Just tried this little programme and I like it. I took my horrible under-steering Callaway inputed the details into GT5Calc and most of the under-steer was gone. A quick ride hight and camber adjustment and it is completely gone.

Before using this programme the under-steering barge would get round Grand Valley in 2:01 now i am getting it round in 1:54.

Very nice programme probably saved me a good hour of initial tuning to get shot of that damn under-steer.

Hey by the sound of all the well received comments this little gem deserves to be a feature of the site, Isn`t there any way it could be uploaded and used on-line much like some of the Forza calculators that exists , or maybe a dedicated web page/site 💡

I probably could convert it to a web base application fairly easily.

 

[springerman]

Well i think you just laid down the gauntlet ,Please it would really help those who are having trouble downloading the software to open this and if you made it web based so many more could access it
If it became super popular it may even attract advertisers (revenue for you)

Does this work on a Mac?

Wanted to give this a spin, got to here, did the download and it still doesn't work.

It's asking for Net Framework: v4.0.30319

but the link downloads Net Framework: v4.0.30319.1

Not sure if that's the reason or not...any help would be appreciated.

I did the same and it worked.
Have you restarted your comp?

Yes, I have found some cars become WAY off from the original weight distribution when weight reductions are done. Some so much that the car becomes almost un-tunable. The Shelby GT350 was one of those cars to me, I have to adjust the weight distribution to 75% front in the calc to get a setup that had a chance of keeping the rear end under it after all the weight reductions I did.

I was reading the posts and i saw a few talking about weight distribution being affected by weight reductions...
Guys come on... look at what happens when you do weight reductions... you take parts off from the car... not all of them weight the same and they are on different points of the structure of the car... we couldn't call GT5 realistic if that didn't actually changed the weight distribution...
in a certain level of weight reduction they say it is installed a roll cage in the car that should almost make the original weight distribution invalid... so... yeah well this program is really really good when you have the original car... but not even a good programmer can make a program guess how the car will be like after weight reduction.

also..

if you're using windows vista or 7 you might not need to download anything you might even have uninstalled it accidentally.
if you're using windows xp you might have had a problem during install in which case trying again MAY sort it out

This should be recommended to be an app. Nice program. I find this VERY useful finding a starting point on my tunes. Here's a suggestion. Is it possible for you to make a tuning calculator that works vice versa to yours. That would be usefull theoretically showing the results of tuning, like a Tuning Grader.

 

[yakuzah]

Great Application.. You really should think about porting to iTunes for iPhone and Android Market. People would pay for this including myself!

Once again thanks

[Litzner]

I am considering porting it, but lately I have been too busy to even fix a couple simple bugs in it.

 

[SZ-Alpha]

Hopefully youll get the time XD. Tuning Grader man

 

[freshseth83]

whats the weight distribution of the race cars? The LM race cars like RX7LM GTRProtoLM?

 

[Litzner]

You usually will have to make a educated guess on race cars. About 50 for FR, and 43 for MR would be a decent starting point.

 

[BradLTL]

Does it... or how does it account for Camber and Toe?

I have researched trying to do camber and toe calculations, but I think there are just to many variables involved, and to make proper calculations I need information from each car that is not usually readily available. I have thought about doing some experimenting to see if replacing some of those values with generic values would get you somewhere close, but it will take quite a bit of trial and error, and I just don't have the time to do that at the moment.

I am going to start working on on version 2.3 next week once I get back from this long work road trip. I would like to get one or two people that can do a little testing with me on some anti-roll bar calc tuning I plan on doing.

Preferably someone who has a wheel, a very good sense of what the car is doing on them, and able to get on Vent to discuss the results.

I doubt that this will help many people but I can load this on a Mac in parallels with win 7, vmware, and virtualbox. Just be sure that your install is fully updated and that .net framework 4 is installed. It is non-standard and in the dev section of windows. This is not new news. However, crossover works as well, you just have to be sure to install the net framework 4 and the tuner in the same bottle. If anyone needs help pm me.

Doesn't seem to work for the Caterham... when I input the specs it tells me that the front springs should be at 1.8, however the minimum is 5.0.

Just FYI...

Make sure you are plugging in the downforce numbers And a appropriate speed number. If you are still getting results that are out of range, increase the value of the stiffness until it gives you values within range.

I uploaded 2.3b. Please let me know how the anti-roll bar calculations feel in comparison to 2.21b.

Changes in 2.3b

- Changed up the Anti-Roll bar calculations to be solely based on the weight and weight distribution of the car. This has not yet had much testing, please give me your feedback on whether or not it feels better then 2.21
- Fixed a bug where the Anti-Roll bar calculations were not clearing when the user pressed clear.

 

[Litzner]

With the 1.10 patch, users no longer need to look ip the weight distribution themselves!

You can find that information on the ballast screen for the car!

Maybe I am a bit to excited about this update...

Does it show the % values now?

 

[Litzner]

Does it show the % values now?

Yes, it shows you the front and rear % values, and how the ballast weight changes it.

That is awesome.

Must... Get... PS3... NOW.

 

[No_OBsT33R]

Sick, one less thing to source online.

Does it change when you move 0 ballast?

 

[Starfirebird]

Now way!

That is awesome.This is one thing GT5 definitely needed. 👍

No, nothing changes.
