Genesis G70 3.3T ECU Tune

On 2022+ Genesis G70 models, the factory shift pops/burbles in Sport+ mode will be removed as part of the tune. This feature causes knock within the ECU and is harmful to the engine. This applies to all tune types unless you specifically request otherwise in a Custom Tune.

All G70 3.3T tunes are built on our custom-developed ECU calibration software. This platform is the foundation for all future R&D, meaning faster issue resolution and access to upcoming features like anti-lag and map switching. Your ECU calibration ID will change after flashing — this is expected. If you ever need to return to a previous calibration ID, you will need a recovery file from EK1 Tuning. All tune support is handled directly by SleepyTuned.

Full Tune and Custom Tune options are not currently available for 2024-2025 Genesis G70 models. Only Backend Flash (BEF) is supported for these model years. If you have a 2024-2025 G70, please select Backend Flash as your tune type.
