Overview of GT7 Telemetry Software

[Met Entso]

Is there any app that would show the time of the last 10 laps or so? I know gt7 already shows this, but not in VR, I'd like to display it in my streams.

Victory dash keeps track and telemetry info on all your laps sorted by track and car

present I'm using EZIODASH Pro as main dash board. And I love the motivation from the box … 😇😊
additional a Android tablet with PRO Sim Dashboard on the side for more information with a little bit bigger letters for my old eyes 🤪

But I like to test @chrshdl solution also 😍
PI4 and a dashboard display 14,5" are on board … I'm curios

Thanks to all developers .. great job 👍🥰

Hi everyone, got some exciting news.

There may be a new packet type. Sending heartbeat C yields a 368 byte response (24 bytes more than the most recent "~" packet).

This is a very recent addition, I'll be working over the next few days to see what's been added/changed.

Feature: "C" telemetry format discovered · Issue #18 · Nenkai/PDTools

I’ve discovered a new 368 byte telemetry packet that can now be accessed by sending the "C" heartbeat. The XOR constant is the same as Packet B (0xDEADBEEF). • [0:4] SurfaceType (char): Indicates t...

I've already found some of the new datapoints, you can see further technical details here. ^

The current stuff I've found is:
Surface Type Indicator (what kind of surface your tyre is in contact with, such as tarmac, dirt etc)
Current Laptime (!!!) (You can now see your exact current lap time, finally.)
Category Type (Which car category you are currently driving)

I'm going to do some more research in the morning, the other fields appear to be harder to decode for me at least.

Did we get only total lap time, or sectors as well?

Only lap-time right now, I don’t see how that would be implemented easily (as there are only 12 bytes left to find out the meaning of, and some tracks have multiple sectors). It looks the last 4 bytes of the 12 bytes sequence is tied to the steering or some kind of yaw. Not really sure as of right now though.

You can now test out my current findings using my library for ESP32/ESP8266 devices.

Yeah I was able to read the new data by looking at your code, thank you!

I don't have a Github account so I'm posting here:

There are more values for the SurfaceType that you guys haven't mapped. Right now I'm in a sandbank and the game is returning me 'S'. It also returns 'G' for the grass.

Hi, sure feel free to test it https://github.com/chrshdl/instrument-cluster

The system currently supports only the Raspberry Pi 2 display.

I just want to throw it out there that EzioDash Pro now has full support for iPad! This is the first version with iPad support, so I would appreciate any feedback on bugs and if there's anything that isn't working as intended.

And no, there is no free iPad version planned at this stage – sorry.

It's basically everything everwhere all at once on iPad

I just saw it, was wondering why the app looks so different
THANK YOU VERY MUCH, GREAT WORK!!!!!

Was anyone able to identify which sector are you on based on Telemetry data?

I know you can draw the track using the coordinates. And with GT7Tracks project you can identify the track. But you still need to map the coordinates of each track that represent Sector 1, Sector 2 and so on.

Coach Dave Delta and Victory Dash has been able to do this, but their code isn't available, neither their track/sector mapping.

I would assume it’s the same functionality as the GT7Tracks project and they just went to the effort of mapping the sectors. I’m not aware of any telemetry data that let’s you see which sector you are on.

Yeah they did that, it was discussed it a few pages behind on this thread.

What I'm asking if anyone also did this and publicized their code/results, so we don't have to do all the mapping ourselves, all over again.

And no, the public API doesn't have sector info. Maybe the private has, but we don't have access.

Any way to get info about abs with the most up to date data?

There are filtered and unfiltered braking inputs.

Hey everyone — figured this was the right thread to introduce something my son and I have been building for a while - Tractivvity

We're a father-and-son team from Indianapolis. We built Tractivvity because we love GT7 and the craft of racing, and we wanted tools that respect the time you put in on track. We're not trying to replace anything anyone here has made — we owe a lot to the work that came before this, and we hope Tractivvity can be a backbone the community builds on.

The short version: Tractivvity is the home base for your GT7 driving. A cloud-based telemetry platform with a persistent history of every lap you record — captured by our own agents on iOS, Android, Windows, or Mac, or by partner apps we'll announce soon. Every lap is automatically uploaded, analyzed, and saved forever. Compare any two laps side-by-side — yours, anyone else's, or a curated benchmark. And Tractivvity Insights is your personal race engineer. Overlay any lap against your personal best, a benchmark, or a faster driver from the community, and get coaching across every data channel we capture — full lap or segment-by-segment.

What makes it different:

• Cloud-first, not local — your lap history follows you across every device, queryable forever
• One account, every platform — iOS, Android, Windows, and Mac agents all feed the same web library
• Server-side coaching — Tractivvity Insights surfaces where you're losing time, lap after lap, instead of leaving you to dig through charts alone
• Community layer — public and private groups, global leaderboards by car/track/category, weekly challenges

We've had an absolute blast developing this. We're in early access right now, and we'd love honest feedback from this thread — the one that helped inspire the mission in the first place. Early access is fully automated and includes all the features, and you'll get some demo laps loaded to your account once you sign up. Things are moving fast, so we'll respond to any questions or issues as soon as we can.
