Will a programmer increase my MPG?
Adding a computer programmer will allow every bit of energy from a vehicle’s fuel to provide more MPG. One of the functions a vehicle tuner can perform is to increase the fuel efficiency of your car or truck.
Can a tuner damage your engine?
Can remapping damage the engine or cause reliability issues? This process puts extra strain on the engine; that much is obvious. But a remap done right won’t go over what your powerplant can handle. Most carmakers limit the potential of their engines for multiple reasons.
Are performance chips worth it?
Performance chips may give you power but will also increase your engine’s risk of a power failure. Advertised gains by manufacturers often do not match real-life performance. Installing a performance chip would void an existing warranty on your vehicle.
What’s the difference between a tuner and a programmer?
First a couple of definitions that probably applies only to my posts: A “tuner” is a person – a computer programmer that writes programs we call “tunes” for our engines. A “programmer” is hardware used to install different tunes into your engine.
Can a trip computer show your fuel economy?
One caveat: If your vehicle has a trip computer that shows the fuel economy on the dash, be suspicious. These can be inaccurate. I’ve found at least one vehicle that showed fuel economy several percent higher than the actual economy during expressway driving and several percent too low while driving in the city.
How does the trip computer work on a BMW?
On average, the BMW’s trip computer reported mileage 1.4 mpg higher—nearly 6 percent better—than calculated. Modern engines are controlled by computers that calculate how many microliters of fuel to inject into each cylinder per combustion cycle.
Why does MY BMW trip computer read higher than the odometer?
Given the vagaries of filling a gas tank to exactly the same level at each fill-up, some variability is understandable. But, in years of doing this, I’ve found the BMW’s trip computer has always read higher than the mpg calculations based on the fuel used and the corrected odometer readings.
Why is my car not giving accurate mpg readings?
“We look at the fuel-consumed data that comes from the engine-control computer, but we also track the float sensor measuring the fuel level in the tank,” says Raj Manakkal, chief engineer for electrical and infotainment devices. He also points out that, due to temperature changes, plastic fuel tanks can expand and contract by as much as a liter.
