We are excited to release our S300 PRO ECU Package! This is a new production OBD1 ECU with the Hondata S300 system. YES, a NEW ECU circuit board with ~80% brand new components assembled right here at our facility! Through a wonderful collaboration with "The ECU Guy" and Herse-Tuning, we are able to offer a brand-new production stunning purple OBD1/P28 spec circuit board. We start with the brand-new board and install all new resistors, electrolytic and ceramic capacitors, as well as many other new components and IC's. Every component that is still available new is sourced and installed. The remaining items that are needed (main processor, etc.) are sourced from our huge ECU inventory and professionally installed. In addition to being a new P28 ECU, we provide and install a new Hondata S300v3 system, add PWM boost (boost by gear) circuitry, and prep for our coil-on-plug system. This full-featured ECU is ready to go for anything you can ask of it. ** This is the complete ECU, including a new Hondata S300v3 system fully installed ** What else do I need to use this ECU? Laptop computer running Windows XP, Vista, 7, 8, or Windows 10 (laptop must have atleast 1 available USB port). Internet connection to register the system. Features: Brand-new circuit board. This is not a refurbished old board, it is a new production unit, in a stunning purple color! This board is produced to be a copy of a factory OBD1 P28 ECU (1720). Approximately 80% brand-new components. Every component that can be sourced new is installed. The remaining items that are no longer produced are sourced and transferred from a used OEM Honda ECU. Brand-new Hondata S300V3 tuning system fully installed and tested Boost by gear / PWM-boost circuitry installed so this can be used with a boost control solenoid if desired Coil on Plug kit headers preinstalled. If you are using, or will eventually use our COP kit, this ECU is already prepped and won't need further modifications. You can still use the factory Honda distributor instead if you want to though or even use a Hondata CPR kit. Uses factory OBD1/P28 ECU pinouts. ZERO wiring changes needed if you are already using a P28 spec ECU. Powder-coated ECU casing for a winning finish, topped off with clear top and bottom lids, and new stainless screws.
