Ported Vac or Manifold Vac
RRR,
It is completely relevant & I am sorry that you cannot see that. The same principles are at stake whether carb or EFI. And I take offence that I am ' gumming up' the thread. Before the thread disappeared, I had provided info & the OP asked where the thread had gone because it contained useful info, some of which came from me. I have also provided many links from a wide range of sources on MVA benefits, in a thread that is about man v ported VA. That is not gumming up a thread, that is providing real time useful info. If you do not understand that idle requirements with EFI are similar to a carbed engine, then you know a lot less than you think you do. The link in post #37 came from an article where MVA was added to a carbed engine. The purpose of finding out the idle on an LS engine, & including it in the article was: to show that it doesn't matter whether carb or EFI, the engine could use that amount of idle timing, because the same parameters are at work in both systems. Below is the original article that compared MVA to PVA [ which is what this thread is about ] & the LS clip was included with it.
