GT7 Tuning Calculator - Download v3.3 all new cars added!!

This looks like a fun bit of kit. There are a few problematic vehicles I'd love to try and tame. Downloading now. Looking forward to givin' this a proper testing. From the comments, this looks to be a no brainer. Thank you for putting this together. Cheers.

Looking at the setup I would have said the LSD settings are about right for an extremely high powered historic car that will shred tires like paper if not handled carefully! You can increase the LSD setting to +5 and get 8, 10, 6. Have you tried any higher settings and found them better?

Have fun!
 
Having a few issues with gear ratios, any idea what I'm doing wrong:

Hey @hookedonturbo ✌️

So following up on this topic, I have actually tried tuning various cars with varying levels of LSD Settings and still stuck at the 5 6 5 values everytime (calculator lite). E.g with this NSX I am tuning for a league with custom BoP I managed to get a great suspension setup but the suggested LSD of (5 6 5) is just undriveable, especially due to the aggressive braking sensitivity setting for a high powered MR car.
I actually ended up using (5 60 60) on Suzuka and (5 60 40) on Barcelona.

Hence, I believe this has to be some kind of an issue 😬🤷🏻‍♂️

Ok I’ll do some more research into this. Bear with me while I come up with a fix.

Yes wrong screenshot uploaded.

Only use the ecu selection screen, not the power adjuster

Sorry, Still having trouble with this : These are my results and my uploaded screenshot, this time using the ECU output. I'm screenshotting within PS5, uploading to PS App, downloading from PS App on phone to photo album and uploading to Pro Tune from there.

Hey buddy,

Just looked at your settings you posted for the GT500, the torque figure is wrong. You have entered 7500 KGFM!
 
Hi, I bought your app and I have to say I'm totally impressed.
After several tries, I've managed to get very consistent results on a variety of vehicles.

The only criticism I have is the management of the differential adjustment, which I don't find relevant.

For better operation, why not use the explanatory document that Praiano published as a reference?

In any case, thank you very much for your work, keep it up👍.

F3500-A. the Natural Frequency range is 4.60 - 5.50 for front and rears but the calculator is saying to set to "Spring Rate 8.06 6.36"

The formula cars and other extreme performance vehicles will have majorly different ways of being setup compared to the road cars, reduce the spring frequency adjustment selection down to the lowest level. If that still doesn’t get you there, only use downforce number divided by 2. Eg. 600 867

We have a soft launch coming very soon with the full blown launch more than likely in line with the latest update, however we will be releasing the excel version with the last few updates worth of cars in for those of you who don’t want the app based version yet!

Hi
I’m new on that forum. Try to download calculator but I can’t find the link
 
Hey all.... I hate being the dumb American guy, but here we are.
I've followed your YouTube tutorial multiple times and I'm fairly certain I'm following it correctly, but my gear ratio results fall far under the minimum setting on the gear settings window. From other issues people are having there is a tire ("tyre" lol you brits ;-) setting issue? I dunno, but your expertise would help. Some screen shots are attached. Thanks and really thanks for putting together this app (and the associated math).

Hey Bud,

Looks like your speed is incorrect… or should be the top speed on the gear that you have entered I this case 5th.

Yep, made that change, changed the tire size (26.59) of course, but lowered ever further the gear ratios.

Your torque graph looks off, have you uploaded the screenshot from the racing/sport/standard ecu selection (not the power adjuster)?
