• Update Costs: Keep in mind that ECU protocols are always changing. Always learn more about the ongoing subscription or update fees. It usually comes into play once the free period comes to an end. Brands often provide 2–3 years of free updates, like XTOOL and TOPDON; just know which one can offer better value for your money. 

• Local Support: This is a must. Look for Brands with Australian distributors for performance vehicle scanners and major sellers. You can get in touch with Autolines for Autel, XTOOL, and Launch. They can make warranty and technical support much more accessible.
