I’ve purchased a few tools in the past that have been okay but no of them coded injectors and this was the main reason for purchasing. I’m so glad I did not only did it code the injectors without a problem but many other things on my bmw and wile the other purchases are limited to bmw/mini this also read and clears the faults of a Fiat 500 and works on every car brand so far. It’s brilliant and very fast and cost effective. With free lifetime updates I can’t see how you could go wrong. If I had to pick at something it would be the screen could be bigger but if that’s an issue xtool sell other tools for a bit more money that have bigger screens and do even more amazing things. But if your looking for the most cost effective this is definitely the one.
