I'm a show me type of guy. I trust salesmen about as much as politicians. I cannot think of a single time anything ever worked as good or as easy as a salesman told me it would. I can think of dozens of times it was a flat out hunk of junk.
I feel a mass flow EFI has a better chance at plug and play than speed density does. When you get to high overlap cams, where the vacuum at idle is lower than it is at say 2000 rpm, speed density doesn't have a chance. Alpha n (think that is the term) is used, which is based off of throttle position.
The more stock an engine is, the better chance these self tuning systems will work. The more modified the engine, the less likely this is going to work.
Maybe I'm living in the past. I just don't buy it. I've seen videos of some set ups, but the engines were all mild. They never show you the AFR on the dyno. You never know how many hours was edited out. I'm still not a believer.
