33920-81C90

This is an ECU from an EFI Samurai with the 8V 1.3L engine, the ECU is very similar to those used in the 1991-96 Sidekicks, Trackers and Vitaras. The processor is a 76C75/MH6111, One Time Programmable (OTP) device, I can read the internal memory on these devices using my ROMReader PCB. As standard these ECUs cannot be reprogrammed however I can modify these with a daughterboard that allows them to be remapped, the socketed processor on the PCB shown below is non-standard, this ECU is one of my development boards.
