Re: How does VTEC work?

I havnt really looked for the cpu yet to see if it has a diagnostic plug (hope so) any info would be great. How can you tell if its a japanese sold engine?
Usually 5.2K RPM is where it's at from factory. If you feel a boost at 5.5K RPM then thats your VTEC crossover. So when the CEL comes on, it sometime will disable VTEC. So pull the code and figure whats wrong.
