Get Grand Turismo telemetry data from the PlayStation console

GranTurismo

This package wraps the Gran Turismo 7's unofficial telemetry API. By providing this module with you're PlayStation's IP address (as found in the menu) you will be able to retrieve packets containing telemetry data.

Data

Because this is an unofficial API, the range expected min/max of each value is still unknown. As more effort is put into understanding this API, better information will be available. For now, here is what we know.

    • float: rps: Rotations per second
    • float: ground_speed: The speed the tire is traveling on the ground in meters per second.
    • float: temperature: The surface temperature of the tire in celsius
  • Wheel: rear_left
    • float: suspension_height: between 0-1. Lower number equates to uncompressed, higher number to a more compressed suspension
    • float: radius: Radius of the tire in meters
    • float: rps: Rotations per second
    • float: ground_speed: The speed the tire is traveling on the ground in meters per second.
    • float: temperature: The surface temperature of the tire in celsius
  • Wheel: rear_right
    • float: suspension_height: between 0-1. Lower number equates to uncompressed, higher number to a more compressed suspension
    • float: radius: Radius of the tire in meters
    • float: rps: Rotations per second
    • float: ground_speed: The speed the tire is traveling on the ground in meters per second.
    • float: temperature: The surface temperature of the tire in celsius

  • bool: loading_or_processing
  • bool: in_gear 0 when shifting or out of gear, standing
  • bool: has_turbo
  • bool: rev_limiter_alert_active
  • bool: hand_brake_active
  • bool: lights_active
  • bool: lights_high_beams_active
  • bool: lights_low_beams_active
  • bool: asm_active
  • bool: tcs_active
  • bool: unused1 always False
  • bool: unused2 always False
  • bool: unused3 always False
  • bool: unused4 always False
• float: orientation
• float: body_height in meters
• float: engine_rpm 0-?
• float: gas_level 0-100
• float: gas_capacity 100 for gas cars, 5 for karts, 0 for electric
• float: car_speed in meters per second
• float: turbo_boost this value - 1 gives the Turbo Boost display
• float: oil_pressure in bars?
• float: oil_temperature in celsius. Seems to always be 85.0
• float: water_temperature in celsius. Seems to always be 110.0
• int: time_of_day millisecond timestamp, time of day indicates race start time of day, affected by Variable Time Speed Ratio, useless for timing when time speed ratio is not 1
• Optional(int): start_position only available before race starts, otherwise None
• Optional(int): cars_in_race only available before race starts, otherwise None
• Bounds: rpm_alert
  • float: min 0-?
  • float: max 0-?
• int: car_max_speed in meters per second
• float: transmission_max_speed corresponds to the Top Speed setting of a customizable gear box in the car settings, given as gear ratio
• int: throttle between 0-255
• int: brake between 0-255
• float: clutch between 0-1. This seems to correlate with the clutch peddle
• float: clutch_engagement between 0-1
• float: clutch_gearbox_rpm
• Optional(int): current_gear 0-4: current gear, 0 is reverse, None is neutral
• Optional(int): suggested_gear. None if there's no suggested gear
• List(float): gear_ratios 1st - Nth gear.
• int: unused_0x93 always 0
• int: unused_0xD4 always 0

Usage

The main function is the Listener, which is a closing object. You can use a with Listener(ip_address) as ... clause to open and close the listener. The Listener will spin up a background thread to maintain a heartbeat connection with the PlayStation, so it's important to always close the object.

Quickstart example

Grab a single packet from Gran Turismo and print it

from granturismo.intake import Listener
import sys

if __name__ == '__main__':
  ip_address = sys.argv[1]
  with Listener(ip_address) as listener:
    print(listener.get())

Streaming data example

Stream all incoming data from Gran Turismo and print it to the terminal

from granturismo.intake import Listener
from granturismo.model import Wheels
import datetime as dt
import time, sys
import curses

stdscr = curses.initscr()

def report_suspension(wheels: Wheels) -> None:
  pad = ' ' * 100
  curr_time = dt.datetime.fromtimestamp(time.time()).isoformat()
  stdscr.addstr(0, 0, f'[{curr_time}] Suspension Height{pad}')
  stdscr.addstr(1, 0, f'\t{wheels.front_left.suspension_height:.3f}    {wheels.front_right.suspension_height:.3f}{pad}')
  stdscr.addstr(2, 0, f'\t{wheels.rear_left.suspension_height:.3f}    {wheels.rear_right.suspension_height:.3f}{pad}')
  stdscr.refresh()

if __name__ == '__main__':
  ip_address = sys.argv[1]
  listener = Listener(ip_address)

  try:
    while True:
      packet = listener.get()

      if not packet.flags.loading_or_processing and not packet.flags.paused:
        report_suspension(packet.wheels)
  finally:
    curses.echo()
    curses.nocbreak()
    curses.endwin()
