Fi=People who can’t tune and can’t use a screwdriver.
I can tune, and use a screw driver. But that sucks, why mess with changing jets and air bleeds, when you can stroke a few keys and jump right back in the lanes. I can usually make needed changes in less time than it takes my water pump and fan to shut off. Should I choose I can do it while belted in. With EFI I actually put more effort into tuning because its so easy, and I have more time to make more passes.
I drive my cars, a lot. I got my old 950 HP dialed in pretty well, but every time I would go for a drive, I would come home and pull the bowls off making PVR and IFR changes and smelling like gas chasing a perfect tune up. Well, it was perfect in the heat of the summer, but then in cooled off in the fall and the car would lean surge down the road...
Now, to see if the car would like more fuel, I click a few buttons and make a pass.
You still have to tune EFI, dropping a self-learning system on is the equivalent of dropping 750 Holley on out of the box and expecting it to be great.
Regarding injector placement. Most OEMS make decisions based on (1) emissions (2) packaging. Having the injectors point directly at the valve helps both of these. Moving them up in the runner will improve mixture preparation and charge cooling, i.e. moar power.
