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.
