I'm not sure that our cars are even OBD1 compliant, no datastream. We have a MECS ECU. You'd have to manually log each sensor on it's own channel. I used Megasquirt for this back in the day.
MECs hasn't really been mapped. You could try running a Honda ECU with hondata or similar, that's been done before. Megasquirt that fits into the stock ECU case would be your best bet for tuning, get rid of the junk distributor and VAF while you're at it
