A Look At How Duramax Tuners Work

Duramax tuners can help you get the most out of your car’s engine.  They plug into the onboard diagnostics port of your vehicle and load custom software, referred to as “tune”, into the engine’s control unit. Most onboard diagnostic ports are located right above the driver’s side footwell at the bottom of the dashboard.

Tunes are simply pre-generated instructions that tell the engine’s control unit when to spray fuel into the engine, how much to add as well as how much to ignite based on the signals from the engine sensors. These adjustments can be tweaked, something in turn allows tuner manufactures to tailor how much fuel economy or extra power you will get by using their tuners.

Once a performance tune is uploaded or flashed to your vehicle’s engine control unit, you can disconnect your tuner and leave it at home. The performance tune stays in your vehicle’s computer and will load whenever you turn up your ignition.

When you are driving your vehicle, the engine control unit will follow the instructions that the tuner left to optimize either power or fuel economy depending on the tune that you loaded. Performance programmers can also enable you to restore your vehicle’s factory tuning for warranty or service purposes.

So exactly what can Duramax Tuners do for your ride? Once installed, these tuners will increase the horsepower as well as torque by 5 to 10 percent on average. Most tuners will increase fuel economy by 1-3 MPGs, but you should not take advantage of the extra power that a programmer provides to see any noticeable gains.  Programmers usually increase throttle response and eliminate the built-in throttle lag, which is a very common trait in trucks and cars with drive-by-wire throttle bodies.
