@Wotever Maybe Simhub can use this

With the launch of the June CU for Forza Motorsport 7, we're including a new Data Out feature, which outputs a UDP data stream which players can now take advantage of. This is the same technology that powers the motion sleds that Turn 10 uses, but the possibilities are endless. For those interested, here's a look at the parameters:

Telemetry output sends data packets for outside use by third parties. Designed for motion sleds, dashboards, data logging, etc. You can use it for whatever your imagination desires. This one-way UDP traffic is sent to a remote machine at 60fps. Localhost data streaming is not supported.

The initial data structure is designed specifically for motion sleds. We are working with several peripheral manufacturers and will be adding many more data points in the future.

Input Parameters
The following parameters are now located in the HUD options menu.

• Data Out: Toggles the data output function on and off.
• Data Out IP Address: The target IP address of the remote machine receiving data.
• Data Out IP Port: The target IP port of the remote machine receiving data.

Output Structure
Data is output in the following structure.

s32 IsRaceOn; // = 1 when race is on. = 0 when in menus/race stopped …

u32 TimestampMS; //Can overflow to 0 eventually

f32 EngineMaxRpm;
f32 EngineIdleRpm;

s32 CarOrdinal; //Unique ID of the car make/model
s32 CarClass; //Between 0 (D -- worst cars) and 7 (X class -- best cars) inclusive
s32 CarPerformanceIndex; //Between 100 (slowest car) and 999 (fastest car) inclusive
s32 DrivetrainType; //Corresponds to EDrivetrainType; 0 = FWD, 1 = RWD, 2 = AWD

Yeah, I have it in my visor :D, sadly this data is really "feedback" oriented, no lap info, no time, no track ... well a lot of vital data lacking, it means it will work but with a really basic behavior (no map, no performance tracking....), obviously that's better than nothing :D
