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.

  1. Dean Gonzalez

    I’m really impressed with the Stage1 tuning service for my 2015 BMW 435. The installation was straightforward thanks to their plug-and-play setup, and the power boost is noticeable right away. Shipping was quick and reasonably priced, which made the whole process hassle-free. Their team also answered my questions promptly, which gave me confidence throughout the upgrade.

  2. Bruce Jenkins

    The Stage1 tune gave my 2015 BMW 435 a serious boost, and they had it programmed quickly with flawless results—plus, the free shipping was a nice bonus.

    Great communication throughout the process and the plug-and-play setup made upgrading my 2014 BMW 435’s ECU super easy and hassle-free.

    I was impressed by the fast turnaround and top-notch tuning service; my 2013 435 feels completely transformed with 370 HP and flawless drivability.
