Im trying to understand how an fcd affects fueling so hoping someone can help. The fuel cut defender intercepts the signal from the MAP sensor. On the 4efte the map sensor shows roughly 4v at 0.85bar. The ECU will cut if it sees over 4v. A clamp type FCD such as an HKS will not allow a signal higher than 4v to get to the ECU. Does that then mean that, if i am running 1bar of boost, and reach 0.85bar at 2200rpm, the ecu will only see 4v from then until redline? So the ecu can only calculate fuel for the engine running up to 0.85bar. So running at 1bar boost will only have 0.85 bar worth of fuel for each combustion?
