Ok Heres the deal i've got to drop a obd0 engine into a 93 ex civic. I'm going to keep the original transmission obd1 but the motor is obd0 I Have a obd0 pg7 that I would like to put in it so that I don't have to change the distributor. I've heard I could convert the distributor to work with obd1 but then the maps would be off and having the ecm mapped isn't an option at the moment. Is there an obd1 ecu I could use. Or should I just convert to obd0? Another thing all I see is obd0 to obd1 conversions. Topics what about an obd1 to obd 0 topic anyone seen or know anything?? Also I plan on using obd1 high impedance injectors.
