More connections does not equal more reliability. This is a fundamentally basic statistical deviations formula.
What ECU and fuel injection offers is greatly improved fuel economy, better cold, hot, low, high altitude, and high humidity operation.

Code readers are NOT a means to an end, period.
Been there, done that. Code reader offers a suggestion. From there it's parts substitution, then process of elimination and perhaps it's a connector gone bad. I've chased hundreds of phantoms where a code might read bad mass airflow sensor but in reality it turned out to be an oxidized throttle position sensor connector.

Saddle up the burro. Yesterday Martin was fooling around with a code reader on a malfunctioning car. The reader suggested ninety-nine different problems. I showed Martin how to do a cylinder balance test by disconnecting spark plug wires one-by-one and looking for the cylinder that did not drop RPM's. He found it. Number 3.
People are too caught up in this modern******for my taste. If it's simple, make it complicated, chant hocus pocus, and charge four times as much.
A GOOD ECU troubleshooting shop has, not an exaggeration, thousands of parts for substitutions when troubleshooting. Might as well search for an ICBM missile silo down here...
