Im thinking about buying a civic 2002 Si , but with the engine broken and ecu broken too, , I've been researching about the ecu and more to see if its worth it, my question is , I know that k20a3 has no distributor , and therefore there is no way to install a obd1 ECU , not 100% sure , but correct me if Im wrong ...... then , is it a good deal if the car is worth half price ? . is there any other solution for the ECU ? what about key immobilizer ? , how that things works ? that can be disabled or reprogramed , and how ? . thanks in advance for all the help.
