I recently installed a p28 ecu(chipped ,mapped for 450cc injectors,dsm)) into my car (99 honda prelude)and once I started it up it trew code 8 and 22 which were not there before,I checked the wiring but it seems to be ok.I heard some places that you should use an obd 1 distributor with a obd1 ecu is that true?The car is idleing like ****.Thanx for any advice
