People dropping FI setups like hot potatoes

These points are worth reposting.
. Most people...want a completely bolt on, self tuning, hook up 2 wires and go system
And that's what most people are led to believe they are buying. A lot of marketing, including some toadies for the manucturers, go around saying just that.
Do the research, spend the $ on the fuel delivery, wiring, and charging.
Well said. EFI has different demands on the electrical and fuel systems. It sucks when people pay out some serious cash, often hard earned dollars, and then find out that the EFI package alone is not enough.

EFI project is totally cool if that's what you are into. And also I totally get it if you're not into crazy analog emmissions controls but want to set up an emmissions compliant vehicle. But the point is, its not a plug and chug. Ironicly, without emissions, a carburetor basically is. Carbs respond to what an engine demands. Whether its by how hard the engine is pulling, or by velocity past the boosters, the carb provides what the engine asks. Its why we can get pretty close with a generic carb and changing jets at the drag strip or dyno.
it’s because the vehicle they are used on demand simplicity due to their intended use and the class rules dictate a carb.
Another point somehow forgotten by the salesmen. For anyone thinking about some sort of competition, whether its dragstrip or autocross or something else - its definately worth checking the class rules!
