VAFC Tuning (Modify Vtec Engagement)

I bought my car with a VAFC installed already. It is the older silver/blue one... not the newer one. I was wondering if anyone knew how to change the vtec engagement i think it is hitting around 5800 right now. I would like to lower that. thanks

have someone that know's what they're doing tune it for you with a dyno and wideband. just changing things without knowing what you're doing can easily hurt something.

Hitting madd B-tak earlier will actually make less horsepower if it doesn't need to be that low.
