EFI is affected by LSA. While it’s true you can make EFI work with a tighter LSA, it requires a very good understanding of tuning dynamics. It’s important to call it like it is and be clear that a 112+ LSA plays much nicer with EFI than say a 108. I’ve seen many engines with tight LSA and EFI that just don’t work like they could. I’ve seen a few that do because the builder/tuner really knew their stuff. Overlap plays a big role in how well EFI works. EFI likes minimal overlap and a steady manifold vacuum signal to really shine. Unless you really know what your doing and build with the parts best matched to a tighter LSA, if you plan to go EFI, you will be much happier in the 112+ range.
