After relentless research and testing, our Hondata S300 V3 / OBD1 AUTO ECU Package is here! This is the tuning solution you've been waiting for if you have an automatic transmission Honda or Acura with a B, F, or H series engine and are tired of being told you don't have a tuning option. IMPORTANT - This ECU MUST be used with a separate automatic transmission control unit (TCU/TCM). This ECU is designed to allow full communication between the S300 / OBD1 AUTO ECU and the TCU, resulting in a great solution for those wanting to run a tunable ECU in their automatic transmission vehicle. Will NOT work on vehicles with a D series auto transmission. Only compatible with B,F,H series auto transmissions. You must use a separate transmission control unit that is compatible with your specific transmission. This ECU is developed to be used with the Hondata Smanager/S300 software for OBD1 Honda / Acura applications.
ECU Casing Option: We have two ECU case options for you to choose from
- Standard Case: This is the standard bead-blasted casing. This is a clean, like-new finish to the standard ECU casing. (see photos)
- Powder Coated Case: This is the new option to have the casing powder coated in our hammertone grey just like the ECU lids. (see photos)
ECU Covers Option: We have two ECU cover/lids options for you to choose from:
- Standard Covers: This is the standard powder coated grey top and bottom covers.
