Idle Speed Modify (Idle RPM Correction) – ECU Remapping Service

Eliminate rough idle, engine shaking, and stalling caused by an incorrectly low idle RPM setting. Our Idle Speed Modify service manually recalibrates your vehicle's minimum RPM / idle condition directly in the ECU, restoring smooth, stable engine operation at a stop.

This remap is performed on the original ECU file (no hardware changes) and is compatible with a wide range of manufacturers and ECU platforms, including:
