In this episode of my 2019 Subaru WRX STI build, I dive into self-tuning the MAF (Mass Airflow Sensor) in closed loop—a crucial step in dialing in your tune after installing an intake, downpipe, or other airflow-related modification. If you're into DIY Subaru tuning, WRX mods, or STI performance upgrades, this is a must-watch!
Using RomRaider for data logging and ECUFlash for flashing adjustments, I break down the process of MAF scaling to correct your air/fuel ratios. Learning how to properly adjust and calibrate the MAF sensor is critical after adding intakes, a downpipe, or other airflow-related mods, ensuring your EJ257 runs efficiently and safely.
🔧 What You’ll Learn in This Video:
✅ How to log and analyze short-term and long-term fuel trims using RomRaider
✅ How to adjust MAF scaling to optimize air/fuel ratios using a MAF Scaling tool for closed loop operation
