HONDA B/D OBD1

This is a Plug and Play Standalone ECU for the popular Honda OBD1 92-00 Civic/Integra. It has a VR conditioner specifically designed for the OEM Distributor and modification is not required. It has Bluetooth connection and a pinout for a wideband controller. The ECU case is 3D printed from either ASA or ABS which can withstand summer temperatures up to 80C. If aftermarket injectors are installed, it needs to be high impedance.
From version 8 onwards, the VTEC relay has been replaced with a MOSFET, and Bluetooth connection uses Serial 3.

The stock MAP sensor is used and good up to 160 kPa (8psi). The AC and Alternator control still works with this ECU. A free base tune is included and can run the engine, but final tuning is required. A separate wideband controller is a must to properly tune the engine. Every ECU is tested with an actual engine to test the functionality.

For OBD2A or OBD2B connectors, adapters to OBD1 are available in the shop.
Please message which base map to be installed or else a B20 base map will be installed by default. A custom firmware is installed at the time of purchase, DO NOT UPDATE THE FIRMWARE! Visit the Documentation Page to check the Base Map and INI file.
