[DISCUSSION] F1®25: 2026 Season Pack UDP SPECIFICATION

EA_Groguet​ The deep dive video on youtube mentions a boost mode and an overtake mode for the battery system. But the UDP spec document has no term called boost. Is this something that's supposed to be covered under m_ersDeployMode in the car status packet? I see the new Car Telemetry 2 packet has info regarding overtake mode, but nothing regarding boost mode

Hey there.

You are right, it is covered in m_ersDeployMode. The data in the Car Telemetry 2 packet is correct for the new overtake mode and has nothing to do with boost.

I'll update the documentation PDF with the correction and the text file.

Quick question about how is MyTeam 2026 going to be handled with the previous spec (2025, for example) - considering the number of drivers has changed, will it output only 22 drivers, or will it somehow handle 24 drivers instead?

The grid will be 11 teams and then your team so 24 on grid

Not exactly the answer I'm looking for. From my knowledge, the previous UDP specs could handle 22 cars at most. (F2 grid, or MyTeam 2025 and earlier) Now, with MyTeam 2026, we will have 12 Teams total (and total of 24 drivers), and the new 2026 spec is updated to fit that. While various tools will be updated over time with the changes, how will this work with the older specs, since 2025 and earlier are supposed to only have support for 22 cars data? Will we be missing data with older specs for two cars in MyTeam 2026, or are these older specs "updated" to fit the 24 cars grid?

EDIT: Solved the question myself - only 22 cars data is being received, so last 2 cars (whoever may they be in the list) will not send data in a 24-car grid. Also, Team IDs in 2025 spec are a bit different for the 2026 teams (they use IDs 220-230 instead).

I tried FP1 in a driver career mode that i started new and I see that GameMode in Session packet is being reported as 78. This value is not present in the game modes table in the Appendices section. That section might need some updating in the spec doc

EDIT: I see that the new my team uses value 79. Given that the old apxgp story mode is 75, that leaves 76-79 as undocumented. I wonder what 76, 77 are

EA_Groguet​ can you pls advise how to change the battery hud on the 26 game? I've been trying to make to make it smaller and move it but only 25 settings coming up. I've tried in GP mode, open lobby and TT. I can't seem to find it.. Pls help. 

Hey, does anyone have track specified turn system for UDP? Like it would use m_lapDistance to check on where the cars are.

Quick note: When running in F1 26 mode, the UDP still reports as game year the 25, if you send data in F1 2025 format.

And same applies for the F1 2026 format, i.e. the game year is 25, even if you do race in F1 26 mode.

To be fair, that is probably as intended - we're still running the F1 25 game technically, so gameYear output as "25" makes sense.
