Missing Link is a MAP sensor valve designed for use with aftermarket turbo and supercharged applications. By design, it completely blocks boost from reaching the MAP sensor. It does not bleed boost pressure away from the MAP sensor. Instead, once boost pressure is blocked, it uses the principle of diffusion to equalize with atmospheric pressure to simulate a wide open throttle condition for the ECU. Blocking boost pressure protects the OEM MAP sensor from damage.
This approach to “tricking” the ECU from seeing that the OEM normally aspirated engine is now producing boost, also allows the ECU to compensate for changes in operating altitude. Electronic solutions that limit the voltage of produced by the MAP sensor under boost, also known as voltage clamps, will always show the ECU the same voltage regardless of changes in altitude, weather and barometric pressure. Voltage clamps eliminate the ECU’s ability to dynamically adjust to atmospheric changes. For example, a vehicle in San Diego, CA will see a change in barometric pressure simply by going from the beach (sea level) to the mountains. With a voltage clamp, the ECU would see the same voltage at all altitudes. Missing Link is a solution that allows your car’s ECU to make adjustments in fuel and timing curves to compensate for these changes dynamically.
Since the Missing Link is not a bleed valve, it will also allow you to dynamically change boost without making any adjustments to the valve.
The latest version of the Missing Link line incorporates a filtered diffusion port with a calculated micron filter. This latest improvement produces smoother vacuum to boost transition and a longer lasting product that is easily maintained with new filters. Previous design iterations that have now been “knocked-off” incorporate a simple metered hole on the side of the Missing Link for diffusion. This resulted in a dirty valve over time and reduced performance over the most current design.
Guarantee for yourself that you are buying all of the latest improvements to the Missing Link technology, and ask your retailer for the one-and-only Missing Link.
