Quote: The main problem I had when I was an EFI-noob was I really had no idea when good enough was good enough.
Getting the tune close enough to run decently and safely took a lot of time. And even then I was constantly questioning (and tinkering) whether it was ok or if it needed to be tweaked to be better.
Going to a carb on the next build was almost a relief because that is what I was comfortable with. It was easier to just say it was "good enough" and focus on other things instead of obsessing over how much to increase the cold start enrichment or whatever.
Knowing when to quit can be interesting, it's due to the data you have.
To me, that data can only make the car better and better when used for good. With a carb, you set it to how the butt-dyno feels and maybe with a wideband at best.
"Ignorance is bliss" with most carb setups, "it runs fine" gets replaced with "it could be a half-a-point leaner from 5,000-6,200, so I'll pull 0.12ms from the table. Slippery slope, I agree, but I find it hard to want a carb after setting up an EFI car.
