Why don't people do some research before posting...
every car before '92 is obd0, between 92-95 is obd1, and 96+ is obd2.

Also, dont quote me, but the pg7 ecu is a obd0 ecu.

it is OBD0, however, the 86-87 Integra PG7 ECU (which you have) can't be chipped easily, if at all - you could convert the car to run the 88-89 Integra electronic ignition timing advance distributor and then use a chipped PM6 or PM7 ECU

The PG7 is also about as close as you're gonna get for the DOHC zc

that link is for chipping the 88-89 PG7 ECU, not the 86-87, which he has - they are not the same - the 86-87 D16A1 used a vacuum advance ignition timing, so the ECU has no ignition timing maps
