GT7 Tuner — Gran Turismo 7 AI Tuning Assistant

AI tuning assistant for Gran Turismo 7. Send a photo of your GT7 settings screen → get a complete optimized tune via GT Pro Tune calculator. Supports all 581 cars, every track, and any driving style.

Turn any GT7 car into a weapon. Send a screenshot, get a pro tune.

Prerequisites

⚠️ You need a GT Pro Tune account (https://app.gtprotune.com/)

• Free accounts have limited features
• Pro account recommended ($4.99/month) — unlocks full suspension/transmission calculations, Image Analyzer, and Race Engineer
• Sign up at https://app.gtprotune.com/register
• Store your credentials securely (never log or echo them)

When to Use

• User wants to tune a car in Gran Turismo 7
• User sends a screenshot/photo of their GT7 car settings
• User mentions GT Pro Tune, car setup, suspension, gearing, or tuning
• User says something like "tune my [car] for [track]"
• Any Gran Turismo 7 tuning-related request

How It Works

The Quick Flow

1. User sends a photo of their GT7 settings screen (from TV/monitor)
2. Agent reads the values using vision (OCR) — PP, weight, HP, tire compound, etc.
3. Agent confirms values with user (confidence check — only use values that are clearly readable)
4. Agent fills GT Pro Tune via agent-browser automation
5. Agent reads the calculated tune and reports it back
6. User applies the tune in GT7

Photo OCR Pipeline

When the user sends a GT7 screenshot (photo of TV screen):

1. Read the image with vision capabilities
2. Extract all visible values: PP, weight (kg or lbs), HP, torque, tire compound, etc.
3. For each value, assess confidence:
   • High confidence (>95%): use directly
   • Low confidence: ask user to confirm or re-send a clearer photo
4. Convert units if needed (kg → lbs, kW → HP, Nm → ft-lb)
5. Present extracted values to user for confirmation before proceeding

Tips for better photos:

• Take the photo straight-on (reduce angle)
• Minimize screen glare/reflections
• Ensure the full settings screen is visible
• PS5 screenshots via Share button → PS App are ideal (pixel-perfect)

# Credentials must be stored securely — NEVER log, echo, or display them

Important: Angular Input Handling

GT Pro Tune is built with Angular 17. When filling form fields:

• Use agent-browser fill @ref "value" followed by agent-browser press "Tab" — this triggers Angular's change detection
• Do NOT use eval/DOM manipulation to set values — Angular's reactive forms won't detect the changes
• For dropdowns (ngb-typeahead): type the search text, wait for results, then use eval to click the matching option
• For select elements: use agent-browser select @ref "value"

App Structure

Tab 1: Car/Track Settings

Field	Type	Notes
Vehicle	Typeahead search	581 cars, type to filter
Performance Points	Number	PP rating
Weight	Number	In pounds (lbs)
Track	Typeahead search	Type to filter
Tire Size	Number	In inches
Front Tires	Dropdown	Comfort/Sport/Racing × Hard/Medium/Soft
Rear Tires	Dropdown	Same options as front

Tab 2: Suspension Settings

Section	Fields
Base Performance	Front-Rear Weight Balance (%)
Stability	Low Speed, High Speed (text: understeer/oversteer)
Rotational G	G at 40mph, 75mph, 150mph
Suspension	Body Height Front/Rear (mm), Oversteer/Understeer slider
Aerodynamics	Downforce Front/Rear
Race/Track Parameters	Spring Stiffness, ARB Stiffness, Tire Wear multiplier
Other Adjustments	Corner Entry/Exit balance, Offset Spring Frequency

Tab 3: Transmission Settings

Section	Fields
Engine Data	HP, RPM (min/max/peak), Max Torque (ft-lb)
Differential	LSD Setting
Gears	Top Speed (MPH), Number of Gears (3-9), Final Gear, Gear Ratios
Corner Speed	Min Corner Speed (MPH), Min Corner Speed Gear

Vehicle Selection (Angular Typeahead)

agent-browser click @e15                    # Focus vehicle search
agent-browser keyboard type "F8 Tributo"    # Type car name (spaces may cause CDP errors — use partial names)
sleep 2                                     # Wait for dropdown
agent-browser eval "(function(){var items=document.querySelectorAll('ngb-typeahead-window button');var match=Array.from(items).find(function(e){return e.textContent.includes('F8 Tributo')});if(match){match.click();return 'selected'}return 'not found'})()"

Reading Results

After filling all three tabs, the app calculates:

Suspension output table:

• Anti-Roll Bar (Front/Rear)
• Damper Compression (Front/Rear)
• Damper Extension (Front/Rear)
• Spring Rate (Front/Rear)
• Camber Angle (Front/Rear)
• Toe Angle (Front/Rear)

Transmission output table:

• Final Gear Ratio
• Individual Gear Ratios (1st through 7th+)

Differential output table:

• Initial Torque (Front/Rear)
• Acceleration (Front/Rear)
• Deceleration (Front/Rear)

Image Analyzer (Premium Feature)

GT Pro Tune has a built-in Image Analyzer that can extract dyno data from GT7 screenshots:

agent-browser click @e7  # Image Analyzer button
# Upload a screenshot of the dyno/power graph from GT7

Driving Style Presets

When the user describes a driving style, translate to suspension parameters:

Style	Oversteer Bias	LSD	Spring Stiffness	Notes
Aggressive / Verstappen	+2 oversteer	+2 LSD	+1 stiff	Late braking, throttle steering, rotate on entry
Balanced / Hamilton	0 neutral	0	0	All-round consistency, predictable
Safe / Defensive	-1 understeer	-1 LSD	-1 soft	Stability first, forgiving on corner entry
Drift	+3 oversteer	+3 LSD	-2 soft rear	Maximum rotation, rear slides freely

Unit Conversions

• Weight: 1 kg = 2.20462 lbs
• Torque: 1 kgf·m = 7.233 ft-lb / 1 Nm = 0.7376 ft-lb
• Power: 1 PS ≈ 0.9863 HP (close enough to use interchangeably for GT7)

GT7 Tuning Knowledge

See references/gt7-tuning-knowledge.md for:

• Latest patch changes affecting tuning (1.55, 1.66)
• Current meta (post-patch suspension, tire, LSD guidelines)
• GT7-specific physics quirks vs real-world racing
• Track-specific tuning workflows

Notes

• All 581 GT7 cars are supported
• Units: weight in lb, height in mm, speed in MPH, torque in ft-lb
• The app calculates optimal settings — we input specs, it outputs the tune
• GT7 Race Engineer (AI feature) requires a separate subscription tier
• Always verify calculated tunes with a few laps in-game and adjust based on feel
