I put the Honda badges on this car tried to make it look like a stock type R

It’s time for season seventy three of the Forza Spec Racing Series, the weekly beer league of Forza eSports. Where the championship is arbitrary, but the fun is mandatory. We are geared to those who race casually yet cleanly. All levels of ability are welcome.

The season will consist of 9 races over the course of 5 weeks. Races will be held once a week on Tuesday evenings at 7:00pm Central (US). Each night will last around two hours. The first race night is 10/20/26. Participants all run the same car and upgrades however tuning is allowed. This is a simulation damage series.

Morning folks… Cant see it in the Car collection tab.

Hey everyone,

I wanted to share a passion project that completely changed how I drive in Forza Horizon 6.

Since my laptop can't run the game, I play exclusively on Xbox. For the first month after launch, I drove on automatic like a typical casual. Eventually, to stay competitive in spec-class racing, I forced myself to switch to manual transmission.

The transition was brutal. I had never played racing games on manual before, and since my hearing isn't great, trying to judge optimal shift points purely by engine sound was a nightmare.

I started looking for a phone dashboard app and tested pretty much every free and paid option on iOS and Android. Unfortunately, with Forza telemetry, they all share the same flaw: they trigger shift lights at a hardcoded percentage of the factory redline (like 90% or 95%). That works fine on bone-stock cars, but the moment you upgrade cams, swap engines, or add a turbo, those generic apps fall apart because they have no idea how your actual power curve shifted.

So, I decided to write my own C# plugin for SimHub to process Forza's raw UDP data properly. What was supposed to be a quick weekend fix turned into a 3-month engineering rabbit hole.

Here is what **FH6SmartShift (v1.0.0)** does in real time:

* **Builds a live 401-Band Virtual Dyno (60 Hz):** As you drive at full throttle, the plugin maps your car's actual smoothed power, torque, and turbo boost across the entire rev range and saves a profile for your specific car and tune.

* **Finds the Mathematical Shift Point for Gears 1–10:** Instead of guessing redline percentages, it learns your gear ratios on the fly and calculates the exact RPM where upshifting puts more power to the ground in the next gear than staying in the current one (even accounting for turbo boost drop after shifting).

* **30-Second On-Road Calibration:** When you hop into a new build, gears start as Red `(-)`. You just pull each gear at full throttle to the limiter once until it locks the ratio in Blue `(R)`, and as soon as you shift up, it automatically locks your optimal shift point in Green `(P)` (Power Peak intersection) or Green `(L)` (Limiter optimal).

* **Ghost Limiter & Reaction-Time Buffer:** Detects engines that choke before their visual redline and triggers the 12-LED shift bar with a dynamic lead-time buffer based on how fast your revs are climbing — so you stop bouncing off the limiter in 1st and 2nd gear.

* **Physics Filtering & RWD/AWD Telemetry:** Wheelspin at launch, jumps, puddles, kerbs, and damage are filtered out so they never corrupt your dyno map. The included phone dashboard also features safe downshift thresholds (adjusted for braking dive), a hill-climb downshift prompt, a `SLIP` warning, and a live counter-steer bar for RWD/AWD cars.

I've released the whole project for free under the open-source GPLv3 license. The repo includes the full `.cs` source code, a ready-to-use `.dll` file (just drop it into your main SimHub folder), the dashboard layout, and a full visual guide.

I debated keeping this to myself for a long time, but figured it was time to let the community put my 3 months of trial and error to the test. I'd love to hear your feedback, questions, or ideas for future updates!

Esse dia foi dahora demais, fiquei na minha folga toda jogando

Already second time I'm having this impossible finish in the estate. Anyone else had this problem?

I hate to be cheap but I don't have any money or anyway to pay and azimuth wants a donation. Does anyone have the download? Not asking for game files but the mod to make the game files work.

After working on my previous Forza Motorsport 2 and Forza Motorsport 3 recompilation projects, I’ve started bringing Forza Motorsport 4 to PC using static recompilation.

Here is the first work-in-progress video:

https://x.com/herculabs/status/2110767000557429159

This is not a public release yet. The video is an early technical preview showing the current state of the project.

To follow development, you can find me on X: https://x.com/herculabs

What is this?

The original Xbox 360 PowerPC executable is statically recompiled into native C++ and connected to a PC-compatible runtime through the ReXGlue SDK.

The runtime recreates the Xbox 360 services required by the game, including graphics, audio, input, filesystem access, profiles and content management. The game’s CPU code is compiled ahead of time instead of being interpreted while running.

What currently works?

The project already boots and runs gameplay, with support for:

• Named local profiles with separate save directories
• Xbox and other compatible controllers
• Remappable keyboard controls
• Optional mouse input for the camera
• Installation of the additional content from Disc 2
• Language selection using the original game’s supported languages

The graphics options currently include:

• Internal resolution scaling up to 4×
• Anisotropic filtering
• FXAA
• AMD FSR and CAS upscaling
• Windowed and fullscreen modes
• A 16:9 aspect-ratio option
• Direct3D 12 rendering

Compatibility testing is still ongoing, so this does not mean every mode or configuration has been fully validated.

Custom launcher

The project includes its own launcher, adapted from my FM3 project and available in English and Spanish.

It can:

• Automatically identify the Play Disc and Content Install Disc
• Extract and verify the Play Disc files using SHA-256
• Install the four additional content packages from Disc 2
• Create, select and remove local profiles
• Configure graphics, controls, audio and language
• Verify an existing installation
• Launch the game

It also includes a reversible workaround for the square shadows seen during races. This skips certain exterior shadow maps while retaining cockpit shadows; it is a workaround rather than a complete rendering fix.

An experimental asynchronous shader option is available for testing whether it reduces compilation-related pauses. It can cause some objects or effects to appear late while shaders are being prepared.

Current state

This is still an early work in progress.

The game is running, and the latest changes appear to have improved the experience, but several areas still need testing and polish:

• Intermittent stutter and frame pacing
• Shader compilation behaviour
• Incorrect shadows and other graphical effects
• Audio compatibility across different systems
• Career progression and save behaviour
• Less common modes and local multiplayer

The runtime already caches shaders and prepares previously encountered pipelines at startup, but that does not eliminate every source of stutter.

Xbox Live and online multiplayer are not available.

There is currently no release date. I want to continue testing and addressing the main issues before publishing a first build.

Game requirements

No copyrighted game files will be included with the project.

The recompilation currently targets:

Forza Motorsport 4 for Xbox 360 — USA, Rev 1

Both discs are required for the complete installation:

1. Disc 1 — Play Disc
2. Disc 2 — Content Install Disc

Other regions or revisions may contain different executables and are not currently supported.

You will need to provide your own original game files.

Credits

This project is built with the ReXGlue SDK and benefits from the research and engineering work of the Xenia and XenonRecomp communities.

The race-shadow workaround is based on findings shared by the Xenia community.

This is an independent fan project and is not affiliated with, endorsed by or associated with Microsoft, Xbox or Turn 10 Studios.

I’ll share more progress as development continues. Feedback on the footage is welcome, especially if you notice graphical, audio or timing issues.

Thanks for watching!

every wheelrim and paintjob the same (well,95%)

And then two days ago I got FH2. And now I have to do it all again for 337 cars...

I dont know where to start!
