Why Tune-Up

Built From Real Data. Tuned for Your Car.

Every calibration is developed from real-world logs. Designed specifically for your setup, fuel, and driving style.

Log-based custom calibration
Built specifically for your fuel and hardware
Hybrid platform expertise (330e / 530e)
Real-world tested, not dyno-only results
Supports Bootmod3 and MG Flasher platforms
The Process

How It Works

Every Tune-Up calibration is built through real-world data, not guesswork.

1
Submit your vehicle setup
Tell us your exact hardware, fuel type, and goals. This helps us build a base map tailored specifically to your car.
2
Receive your base map
We create and send your initial custom calibration. This is your starting point for real-world testing.
3
Log your runs
Perform controlled pulls and send us data logs. These logs show how your car behaves under load.
4
We review and refine
We analyze your logs and adjust the tune for better performance, safety, and drivability.
5
Repeat until optimized
We continue refining the tune through multiple revisions until everything is dialed in.

Most cars require multiple revisions to achieve optimal performance, safety, and consistency.

FAQ

Frequently Asked Questions

All tunes are fully custom and built from your logs. Each file is refined based on real-world data from your car.
Yes. All tuning is done remotely. We work with clients worldwide through logs and revisions.
Yes. All tunes are designed with safety and drivability in mind, not just peak power.
In most cases, yes. Because the tune is based on your specific car, fuel, and hardware, it is typically more optimized than generic maps.
Yes. We have extensive experience tuning upgraded turbo setups, including high-boost configurations. We also optimize ethanol blends and water-methanol injection (WMI) to maximize the performance of upgraded turbos while maintaining drivability.
Yes. We often work with cars that are not running correctly on other maps and refine them based on logs.
Stage 1/2 starts from ฿20,000. Stage 3 (big turbo, E85) starts from ฿30,000. Special-purpose builds (track, time attack, race) are quoted individually — get in touch to discuss your setup.
You don't need to bring your car anywhere. After agreeing on scope, you submit your car details via our form, then receive a base map via Bootmod3 or MG Flasher. You drive, capture logs, and send them back. Tune-Up reviews the data and pushes a revised map. This repeats — typically 5–10 rounds — until the map is dialled in.
For Bootmod3 users: full-throttle pull logs covering boost, knock, AFR, timing, and injector duty cycle. For MG Flasher users: the equivalent full-throttle logging channels. Tune-Up will specify exactly what to capture once your build is set up. Quality logs = better results.
Platforms: Bootmod3 (BM3) and MG Flasher. Engines: B48 / B46 (all F and G series variants, including 330e hybrid), B58, and S58. If you're unsure whether your car is supported, just get in touch.
It depends on how quickly you can drive and send logs. Most builds complete in 1–3 weeks. Stage 3 or special-purpose builds may take longer. Tune-Up typically turns around map revisions within 24–48 hours of receiving logs.
