Custom Honda Street Tune Package – OBD1 ECU & Hondata S300 Remote Tuning

Custom Remote Street Tune Package

Our Custom Street Tune Package delivers a fully personalized ECU calibration built specifically for your engine combination, modifications, and performance goals. This is not a generic basemap—every tune is individually refined through real-world datalogging to maximize power, drivability, throttle response, and long-term reliability.

We work directly with you one-on-one throughout the tuning process, which typically takes anywhere from a few hours to several days depending on your vehicle setup. Each calibration is completed remotely through datalog reviews and tune revisions, allowing us to carefully dial in your ECU until the tune is fully finished.

This process is done entirely on your schedule. There is no need to rush through a single tuning session. Take your time with each revision, collect the requested datalogs, and we will continue making adjustments until your calibration is complete.

Why Our Remote Tuning Process Works

Over the years, we have found that 9 out of 10 remote tuning projects reveal something unexpected once real-world datalogging begins. The tuning process often uncovers issues that may not have been noticeable otherwise, such as sensor calibration problems, ignition issues, fuel delivery inconsistencies, vacuum leaks, wiring problems, or other pre-existing conditions.

While we do not perform full mechanical diagnosis or take responsibility for existing vehicle issues, we don't leave you on your own. We work patiently with you throughout the process, providing as much guidance and troubleshooting insight as possible to help resolve anything that comes up.

This is why proper datalogging and multiple revisions are so important. A quality tune cannot always be completed in one phone call or one session. Allowing time to address any unexpected issues results in a much more accurate and refined final calibration.

We've successfully tuned hundreds of vehicles using this proven process over many years. With DGTune, you get more than just a tune file—you get quality tuning, quality support, and a fully completed calibration built specifically for your vehicle. Our goal is to deliver a tune that is extremely accurate, reliable, and as refined as possible, comparable to the quality and precision expected from a professional dyno tune.

Recommended Equipment

For the most accurate tuning results, we recommend:

• Wideband O₂ sensor (Wired to D14, D10 or D12 ECU Input)

• Datalogging capability

• Hondata S300 ECU
  

• Snake Emulator, Demon Emulator, or any other

The end result is a completely dialed-in custom calibration built specifically for your engine, modifications, and performance goals.
