  • Tuning: MAF systems, air leaks and reversion « Moates Support

    IntroductionConstant LeaksMechanically Induced LeaksReversionAs stated in our overview of MAF systems, one of their main weaknesses are air leaks. Whenever air can enter the engine without going through the MAF, weird things happen. There are two principal kinds of leaks that wreak havoc on MAF systems – constant leaks (like a unplugged vacuum port) and mechanically induced leaks (such as a Blow Off Valve or Bypass Valve that vents to atmosphere.) Each leak has a tendency to affect the system differently. In this article, we will try to take a look at what “should” be happening, what changes with a leak and what kind of odd things you can look for while tuning to identify a leak. Reversion presents an additional problem for MAF systems. Reversion is the technical name for when air changes direction and reverses flow. MAFs are not one way systems – they will measure air flowing into the engine and then meter the same air flowing out of the engine when there is severe reversion, causing unreliable MAF readings.
