Can you post a picture of the PCB? I believe the X90 uses the Hitachi H8/532 processor. This is usually a masked ROM or OTP device and it needs an adapter board to be able to reprogramme it. Grid in Japan sell an adapter, you would need to contact them for details of compatibility.

THANKS FOR YOUR HELP! I DO NOT USE FOR DOHC ECU. I WAS TOLD THAT MY TRANSMISSION WAS ELECTRONICS AND CONTROLLED BY THE ECU. DUE TO THAT I WAS TO BUILD A DISTRIBUTOR IGNITION. IN ORDER TO USE THE ORIGINAL ECU X90. IT'S LIKE YOU TOLD ME ABOVE IS MAF! THE JOB WAS NOT EASY TO ADAPT THE ENGINE DISTRIBUTOR SOHC, DOHC ENGINE. . WERE MANY HOURS IN THE MACHINE SHOP! LOL! SATURDAY WILL BE IN THE SHOP WHERE I HAVE THE CAR AND I WILL TAKE PICTURES TO ECU!. WHERE CAN I FIND THE PARTS THAT I WOULD NEED TO BE ABLE TO MAKE THE REMAP ECU? THINGS LIKE THE CABLE THE CHIPS AND FAILURE TO DO EVERYTHING!. AS THIS SYSTEM WORKS THE HONDA CHROME? FORGIVE SO MANY QUESTIONS! IS THAT I HAVE MANY QUESTIONS AS YOU CAN READ! LOL! THANKS AGAIN!
The most straightforward method is to use the ECU from the DOHC Swift, there is a replacement EPROM available that is designed to work with a turbo engine. The X-90 is normally has a MAF and can run OK with a small amount of boost if an adjustable fuel pressure regulator is used. Can you please post a picture of the PCB of the X90 ECU so I can see what processor it uses.
