Shadow vtec / mivec controller for: honda B series mitsubishi 4G series
Being able to move your VTEC changeover point is absolutely essential
when you're trying to fine-tune your VTEC engine. Aftermarket cams and
higher rev limits may prompt you to set the VTEC changeover point to a
higher place in the RPM band for normally aspirated engines.
Turbocharged engines may be better suited with lower VTEC changeover
points to help build boost at a lower RPM
