No. The MAP sensor is what senses manifold pressure. Remember, MAP stands for manifold absolute pressure. An electronic MAP limiter, as I explained above, limits the voltage output from the MAP sensor before the signal reaches the ecu. Options besides a MAP limiter are check valves and the missing link. Check valves are placed in the rubber line connected to the MAP sensor to prevent the MAP sensor from sensing boost. I'm not sure how exactly a missing link works, but you can find info about it by doing a search.

In any case, if you need some way of preventing the ecu from "seeing" boost pressure, IMHO the best way to do that is use a J&S V2.
