Ok here's the deal..............I bought a complete swap B16A2, tranny, and P30 ECU. Only thing is that the guy i bought the engine from couldn't tell me what year Civic it came out of. All i know is that the Civic was a VTI (Euro Spec 1992-2000 Honda Civic) EDM VTi (EK). I'm trying to figure out how to tell if the ECU is either OBD1 or OBD2. Is there any physical way i can figure this out? Please if someone can help let me know i would like to start getting some stuff for the rebuild. Thanks!!!!
