GT7 Tuning Reverse Engine PP ratios

[MidLifePalmer]

Has anyone on here reverse engineered the PP ratios to create true gt7 tunes in a calculator?

The PP score is determined by simulation, you can't reverse engineer it.

Hi, thanks for the reply, I was thinking everything should be under some kind of calculation, so if they use real physics etc for grip, acc, downforce you should be able to recreate a consistent PP generator.

If there’s numbers involved there should be math. Looks like i’ll be doing it the hard way 😔

There are numbers alright, but you're looking at multi-variable non-linear 4D analysis (time and space)

At the minimum you'd have to consider these variables:

• Wheelbase
• Track
• Suspension
• Mass
• Center of mass
• Body rigidity
• Aerodynamic drag
• Front downforce
• Rear downforce
• Front tyres
• Rear tyres
• Power curve
• Turbo lag
• Drivetrain layout
• Gearbox
• Clutch and flywheel
• Differential
• Brakes
• Any hidden variables
• Model year? May be relevant...

A lot of that data is hidden from the player, which makes an already impossible task even harder.
Your best chance is to create a neural network and train it to predict a PP score based on the data you have access to. But even then a realistic goal would be to minimize the errors - you're never going to be able to reproduce the exact PP score.
