I rescently blew a piston rod in my 97 DX hatchback, and replaced the engine with a D15B 3-stage vtec. I have it in and runnin (minor idle problem I contribute to the IAC), but because Im running the JDM ECU that came with the engine I will not be able to pass smog in CA. Correct me if I am wrong, but as far as I have researched there is no US ECU that will run the 3-stage vtec. Can I just swap the double solenoid with a EX vtech solenoid and ECU? or is there more to it than that? Any other Ideas on what I can do to get this to pass smog?
