124 Spider Abarth 1.4 Multiair — MM8GMK 894190AH Marelli — ECU Firmware
This is a high-performance Stage 2 tuning file for the Abarth 124 Spider, equipped with the 1.4L T-Jet Multi-Air engine and a Marelli MM8GMK ECU. This calibration is designed for enthusiast vehicles that have been upgraded with a high-flow or decat downpipe to unlock the full performance potential of this lightweight roadster.

Our Stage 2 remap completely transforms the car's character, delivering a much more aggressive power delivery and a significant increase in horsepower and torque. By extensively recalibrating the Multiair system, boost control, and fueling to work with the improved exhaust flow, this tune provides a thrilling and track-focused driving experience.
