Stage 1 ECU/ECM Tuning Service – FixECM
Unlock Power • Improve Response • Enhance Driving Experience
What Is Stage 1 Tuning?
Stage 1 tuning is a software-only ECU/ECM remap designed to safely increase your engine’s power and torque without requiring any mechanical upgrades.
This upgrade focuses on optimizing factory parameters such as:
Boost pressure
Ignition timing
Fuel delivery
Throttle response
Torque limits
Air/fuel ratios
Speed limiter & rev limiter adjustments
Manufacturers leave a large amount of “hidden power” inside the ECU for reliability margins, emissions limits, and global market conditions.
Stage 1 tuning safely unlocks this potential.
What Is an ECU/ECM Remap?
An ECU (Engine Control Unit) or ECM (Engine Control Module) remap means rewriting and optimizing the original calibration file inside your vehicle’s computer.
FixECM modifies the OEM software to:
✔ Increase horsepower & torque
✔ Improve throttle response
✔ Remove factory restrictions
✔ Optimize fuel and timing maps
✔ Enable smoother, stronger acceleration
✔ Reduce turbo lag
✔ Improve fuel economy under normal driving
This is not a cheap “OBD-flash tool tune.”
FixECM performs full read → remap → checksum correction → bench test for maximum reliability.
How Much Power Will Stage 1 Add?
Power gains vary by engine, but typical Stage 1 increases:
Turbocharged Gas Engines:
✔ +35–70 HP
✔ +50–120 TQ
Turbocharged Diesel Engines:
✔ +40–90 HP
✔ +70–160 TQ
Naturally Aspirated Engines:
✔ +8–20 HP
✔ +10–25 TQ
Every tune is custom built for your specific ECU, not a universal file.

I recently had the 2.0 T Stage1 Tuning Service installed on my 2021 Mercedes-Benz GLA 35 AMG, and I’m genuinely impressed. The increase to 405 HP and 419 FT/LBS really transformed how the car feels—more responsive and much more fun to drive. What stood out to me was how easy the whole process was; the team provided a professional ECU tuning service that was essentially plug-and-play, so I didn’t have to worry about complicated installation. Their customer support was top-notch as well, answering all my questions promptly and keeping me informed from start to finish. Plus, the shipping was very reasonable, which made the whole experience even better. Highly recommend this if you want to get more power out of your AMG without hassle.
