Our Custom Street Tune Package delivers a fully personalized ECU tune built specifically for your engine setup and performance goals. This is not a base map — every tune is carefully adjusted and finalized to ensure maximum power, smooth drivability, and long-term reliability.

We work directly with you one-on-one throughout the tuning process, which typically takes a few hours to several days, depending on your vehicle configuration. Tuning is completed remotely using datalog reviews and tune revisions to dial in your setup accurately.

This process is done on your schedule. You’re free to take your time with each revision we provide until the final street tune is achieved.

We’ve tuned hundreds of engines this way, and the result is extremely precise tuning—often better than a one-day, one-tune setup. There’s no rush on your end; we take our time doing it right, so you don’t have to.

This package is designed exclusively for:

  • Hondata ECUs (including S300)

  • Fully remote capable ECUs (emulator Engine Control Module)

The end result is a fully dialed-in custom tune matched exactly to your engine and modifications.

How the Tuning Process Works

  1. Place your order
