Okay, nobody really does this. But I can't help but notice that there is actually a space for a chip just like in other OBDI Honda ECUs. So this just got me to thinking. What if you could run a B16A, GSR, ITR, or other program in this ECU, defeat the EGR, and use it to run a B-series VTEC motor? I would think that the improved fuel control provided by the five wire oxygen sensor could improve fuel economy without sacrificing power. The lean burn mode could even be helpful on lower compression B-series motors (ie B17A and B18C1). But even for high compression motors, a 1992 California P07 (which has the five wire sensor but NO lean burn) could be used. But would it be possible or worthwhile?
