Apparently it's done through hex with the GT5.0 file from your save (perhaps it has to be decrypted first) . I am going to begin experimenting now. If anyone gets on to something please share! And I will share any progress I make as well.

will edit if progress is made.

I'm trying to have a look into this too, I've decrypted the GT5.0 file and had a look around with HxD and I can definitely see certain values but whether or not those are the actual values which can modify the vehicle in-game I don't know but I'm still testing at the moment...

I'm at the same stage, have tried before but the hp etc only shows up in the garage and doesn't effect the cars. Let me know if you've found anything else, I'll do the same. Thanks

Could you send me screeny of the HP value byte(s) in your Hex Editor?

Well my head hurts now, I've done a comparison between 2 GT-R's, a freshly purchased Black Edition and my own personal Black Edition:

Standard 2012 GT-R Black Edition

My own 2012 GT-R Black Edition

As you can see there is only a very small difference in bytes between a fresh Black Edition and my own tuned Black Edition.

On the fresh GT-R the 4 bytes different are "00 00 00 AA" where-as my own GT-R those 4 bytes read "91 1A 83 6B" which indicates that in those 4 bytes must hold the modified vehicle information, seeing as the fresh GT-R has no upgrades it shows as "00 00 00 AA" or 'bare'.

I'm going to do a bit more investigating tomorrow before work but that's as far as I can narrow it down right now, hopefully that'll be of help to someone as well.

DOUBLE-EDIT:

Something else I just noticed:

There is always a % symbol after what I believe to be each vehicles modified information, but don't quote me on that, just a theory.

I'd love to test this stuff out as I'm mad for GT5 but my PS3 doesn't work

Good luck though guys!

Just to clarify with myself the byte differences between a fresh vehicle and a modified vehicle, I did the same test again but with a fresh Viper ACR and my own Viper ACR:

Standard Dodge Viper ACR '08

Similar thing again, the fresh Viper ACR shows clear bytes compared to my personal Viper ACR, although I'm not sure what the "86" relates to on the fresh Viper... maybe the paint I chose when I purchased it? I also noticed 2 other bytes that were different between a fresh and a modified Viper, but those could mean anything.

I'm off to actually play GT5 now lol but I'll see if I can do some more digging around later.

Hmm you could be onto something there, I'm going to look back into it after work tomorrow, needless to say the mod tool from transformers is "supposed" to be released tomorrow, but then which site would it be if he got banned from GTPlanet

PS if anyone has the modded GTR going around could they send me it so I can look into the value changes from a fully modified GTR

my m8 has it i'll try to get it from him

Source?

Yea I'm gonna keep any eye out to see if there is any saves floating around of the modded Civic so I could compare the decrypted GT5.0 with a legit Civic and see what noticeable byte differences there are...

In the mean time I'm still working on analysing the GT5.0 file for bhp values and so on...
