Wow that's great research Pavel! For engines, I have been finding that changing the values to the 2nd and 3rd engine doesn't do anything... although I am pretty sure my program saves any changes to the 2nd and 3rd engines correctly. And it seems like changing the values for Engine 1 will affect the player regardless of the engine selected in the game. I am curious if you find a similar problem.
I will look through engines parameters today (if will not decide to run some Indy 500 instead
)
BTW tested all chassis values using chassis #3. I hope other chassis behave the same.
I posted a new version of the tool with some more parameters to edit and some changes to the menus. It now uses a parameters.csv which contains all the parameters that can be modified and where they are in each version of the exe. Some of the new parameters I have not yet figured out where they are for Rendition, so far I have prioritized DOS and Windy.

Thanks for update!
I still not sure 'engine placement' and 'weight balance' are actually this parameter. So maybe better to mark them with question(?) ?
Also here are some additinal parameteres for you (WINDY addresses):
DD30C - RF tire life (lower value tyre will wear quckly)
DD310 - RR tire life
DD314 - LR tire life
DD318 - LF tire life
Values below are also for tires I think, but I haven't figured what they do.
DD2FC - tire ??
DD300 - tire ??
DD304 - tire ??
DD308 - tire ??
I think there should be parameter somewhere that set how much grip is lost with tire wear.

Thank you Pavel! I have updated parameters.csv with these values.

I think tire life values length should be 4 - 75890688. Then it's more in line with value in track txt 76000000 that looks like is not used by the game.

Okay, I updated parameters.csv with the 4-byte tire life. Definitely can see a difference when I change the value to 10000000, within just a few laps at Michigan my right side tires are in the yellow. The game does crash when you set the value too low.

It's too bad we can't point this at the track.txt to use the value we have there so it would be more easy to play with.
Personally I would like the tires to lose a little bit of grip more obviously when they get worn (like gp2, but not as aggressive). I feel that with icr2 I always pull my fastest laps when the car is super light at the end of the stint, it's almost like the tire wear degradation is negligible sometimes.
Anyways - this is AWESOME work super proud that you are nailing it!

Could you give me a few pointers as to where the common block in DOS and Rendition ICR2 starts? I'm looking into widescreen support and increasing the view distance. It would be a massive help.
