The Best microSD Cards for Diesel Tuning

Diesel engines, like all vehicle engines, have grown extraordinarily complex over the years, essentially turning motor vehicles into computers on wheels. The benefits have been immense, with vast improvements in fuel economy, driver safety, lower pollution and improved engine reliability.

One of the vital components in these computers is, of course, flash memory. Whether these computer devices are known as diesel programmers, engine performance tuners or gauge tuners, flash memory cards are required for firmware/software storage. They are also used to save the engine performance results so you can examine the data on your computer.

Some manufacturers use SD cards, while others rely on microSD cards. Regardless of the form factor, if you’re looking for a new flash memory card for your diesel tuner there are two critical factors you must consider: Is the card both heat resistant and vibration proof?

Consider the environments this card will be operating in. Extreme temperature swings, running from bitter cold to scorching heat. Constant vibration and shaking. Not all cards are built for extreme conditions, and while one card may perform well in your tablet, it will not be reliable in the diesel tuner built into a truck. You need an SD or microSD card that is “built tough.”

The most popular flash cards used in auto and diesel tuners fall into three categories:

Industrial Grade:  Industrial flash cards are designed for mission critical applications, offering excellent durability, shock resistance and enhanced protection from the elements, including wider temperature support.

High Endurance/Maximum Endurance:  These cards are best in applications where data is being logged and erased constantly.

Extreme/Pro Series:  These models offer the best of both worlds. They rival Industrial Grade cards in terms of durability and have a longer than typical lifespan in data logging environments. Some models also have higher read/write specifications than the other categories of flash card.
