Old-school engine tuning of carbureted engines was really an art form. Changing the jets, adjusting fuel flow and air screws and playing with the choke to get the engine to run properly are quite different from today’s process of changing values and coding within the engine’s computer, which controls several performance aspects including electronic fuel injection, spark ignition timing and shift points.

Now we talk about old-school tuning on engine computers, which involved physically opening the case to remove a chip from the motherboard and replace it with an aftermarket version. Changing chips (or “chipping”) was limited to the programming on the chips themselves. 

Changes in emission control requirements added a method for accessing the programming in most vehicle computers. The On-Board Diagnostic-II (OBD-II) connector found in vehicles from 1996 and later usually offers an option of “flashing” the chip or computer itself with new programming.

UNLOCK THE POWER

Why do tuners and programmers offer gains over results achieved with stock vehicles? Vehicle design engineers answer to many masters. They have specific fuel economy, emissions, durability, warranty repair, potential noise and other targets they need to hit as established by complicated government regulations. At the same time, the customers want power, performance, fuel efficiency and usually low noise in their vehicles. It’s a delicate dance to make all these factors come together in each model. 

Aftermarket calibration of the vehicle’s computer can unlock some of the power that was lost in compromises programmed into the factory configuration. 

Aftermarket tuners and programmers are particularly effective when combined with other modifications. The ability to change the calibration of the Engine Control Unit (ECU) allows you to take full advantage of the better breathing available from free-flowing exhaust and intake systems.

For turbocharged engines, both diesel and gas, more power is readily available by raising the boost levels of the engine. Most modern turbocharged engines are overbuilt and can easily handle more boost than they run at stock program levels.

Programmers that control transmission parameters can make changes to increase transmission longevity despite increased power and torque. Changes in line pressures and shift points can help protect automatic transmissions from the extra strain created by increased torque unlocked with performance programmers.

PROTECT YOUR INVESTMENT

Earlier versions of programmers increased power at the risk of increasing the wear on engine components. However, the monitoring systems built into today’s tuners can prevent this and other catastrophic failures that the engine may be subjected to while towing.

Towing is considered an extreme duty for your vehicle, requiring more frequent oil change intervals, and should prompt you to be extra diligent about maintenance. The extra load exerted on the vehicle — and the engine, specifically — means higher oil, coolant and exhaust gas temperatures.

If your trailer and payload weight are in line with the manufacturers’ ratings, all of the stock components have been tested to be safe for towing. However, having the extra safeguards available with many programmers can be an added benefit.

Some tuners take advantage of an auxiliary exhaust gas temperature (EGT) sensor — which is very useful, especially in diesel engines. If the EGTs reach dangerous levels, the programmer can defuel to reduce EGTs. It’s a good idea to try to keep EGTs lower than 1,200 degrees Fahrenheit while towing. 

The design of the tuners can vary. The ability to choose different levels of calibration, including modes specifically designed for towing, is standard fare. Some simply reflash the computer and include no other interface. Others include sophisticated touch screens, wireless connections and data logging capabilities. 

Some models allow on-the-fly selection for power to pull a mountain pass and then switch back to mileage mode at the touch of the screen or a button. Built-in display gauges and the ability to reset engine codes are among the most popular features truck owners look for in programmers.

Some tuners allow you to change the calibration of the speedometer to correct for larger-than-stock wheel and tire sizes, program a change in final drive of your truck and to change or remove the speed limiter from the stock computer.

CUSTOM TUNE

If you don’t find enough tuning options in preset programs, look for programmers with custom tuning capabilities where a professional can calibrate specifically for your vehicle and your hardware modifications. Custom tunes are more useful for less common modifications or more extreme builds. Some have calibrations that are tested and designed to work with specific aftermarket intake and exhaust setups. Look for custom tunes for specific modifications that you can download.

When choosing a tuner/programmer, look at all the benefits and make sure it includes the features you want now and possibly need for the future. You’ll notice more torque for towing, which you can use to maintain normal speeds pulling hills or to pass those drivers with stock vehicles that have problems pulling grades. 

Finally, be aware that the use of some engine program and tuning modification products can affect the coverage on a newer vehicle still under warranty. The engine-tuning products may also run afoul of state or federal DOT vehicle emission standards. It’s a wise idea to ask for specific information from the tuning-product manufacturer concerning warranty claims, emission certification and the like to avoid any unexpected surprises later on.

RETUNE
Stock gasoline engine programs allow for the range of octane ratings the engine may encounter, whether by owner choice at the pump, regional restrictions or the occasional mistaken fill with a lower octane. If you know that you can consistently fill your tank with high-octane gasoline, you can retune the engine and gain a significant improvement in power. Enjoy the power but be sure to watch that octane level.
