Bump. It is possible that I will need a new ECU (i.e. ECM/PCM) in order to resolve my ongoing running problems. They cost $819 from the dealer, and my dealer says the 1998 DX ECU is no longer manufactured. Therefore, if I really need a new one, here's my chance to switch-out for something else. To work properly, the HX ECU would require an HX head, different spark plugs, EGR, and a wideband O2 sensor but nothing else, correct? I guess, alternately, I could chip an OBD1 DX ECU, perhaps. Thoughts?

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
