You could map an obd2 ecu but its not really effective, the ecu will try to go back to its OEM program and you will end up back to stock. It's just not effective.
recomend you get the obd1 ecu, from eg, could be p28(d16) or p30(b16), solder in the socket for flash chip, and remap it then, you would need the conbersion cables obd2-obd1..
