Electronic Fuel Injection - Tune Up

Lets talk about standard, original electronic fuel injection systems that your modern fuel injected car was delivered with when it was brand new.

Modern fuel injection systems do not need a "tune up" every x thousand miles or kilometers. In fact, there is no factory adjustment for a technician to "tune" a modern fuel injection.

Rather than a tune up, modern engines need to follow a regular maintenance schedule to ensure all of the systems on the engine are working correctly, so the engine can continue to operate as the manufacturer intended.

There are, of course many items than need to be inspected, or replaced during the scheduled maintenance program. These include fluids (oils, coolant), air filter, sparkplugs, and more.

If these items are not attended to in the proper course of the vehicles maintenance schedule, your vehicle may start to lose power, it may start using more fuel, and it may not idle as smoothly as it did when you first bought it.

So, if you are not modifying your engine or its accessories (such as exhaust, intake manifold, turbo, etc) you do not need to have your engine tuned up.

If on the other hand, you are modifying your engine, your engine may well get to the point where it's operating outside of the parameters of the original electronic fuel injection system.

You engine may run very badly, and it may even make less power than it did when it was standard, as the original electronic fuel injection system may be making calculations based on incorrect information.

To overcome this, you need to look at an aftermarket electronic fuel injection system. These systems are now very capable and flexible, and can control most accessories on your vehicle, including many automatic transmissions, while at the same time, controlling your modified engine.

So, if your engine is standard, scheduled maintenance is for you.

If you have modified, or are looking at modifying your engine, it's worth looking into what options you have in regards to programmable electronic fuel injection.
