Hondata modifies standard OBD I Honda ECUs, adding features and expanding the capabilities of the ECU (to read boost for example). For best results naturally aspirated ECUs should be tuned to each individual engine setup and forced induction ECUs need to be tuned by an experienced tuner. If you have Stage 4 and the Pocket Programmer , you can tune stages 2 and 3 for others.
When purchasing a Hondata unit, we offer a base program to get you started. From there we offer tuning services to help you get the most performance out of your Hondata unit based on individual applications.
Each system has a variety of configurations, options and features, some of which are specified when purchasing the unit, others which may be added later on.
