Opinion: Small motors more or less consistent than big motors?

In my experience EFI cars are generally very consistent, especially OBDII stuff. Its constantly monitoring and correcting for air temp and pressure, as well as engine temp.

Of course, FWD can make a car very inconsistent, and drive by wire can make cutting a good light impossible. I'll bet an automatic V6 Mustang straight from the factory with a sticky tire would be murderously effective, if you had a model that was pre drive by wire (04 or earlier).

Also of course this contravenes the faster is better theory, but the modern EFI stuff definitely throws a confusion factor into it.

I'm not sure how an EFI car could even run if the MAF was disconnected? It would be running on idle fuel trims at all throttle positions.

Did you mean the MAP sensor?
