hi.. i have a 00 civic si with a jdmB18c swap... when the project was done.. i try to see if theres any code or check engine light.. it link up with 3 codes... then i bought a skunk2 intake manifold had my brother installed it for me.. now when i tried to pass the inspection.. it wouldnt link up.. it says link error.. meaning it cant read... could it be the wiring misplace or harness wire jam? oh yea... im currently running obd1 ecu.. and all that but the main im concern is the linking to the obd2 which did read at first and now not anymore =(

 

OBD1 ECUs wont communicate with the DLC port, neither will an OBD2 JDM ECU.
