Hello,

I am new to the field of ECU tuning and need advice regarding the purchase of necessary equipment. While reviewing the available options, I found that the most commonly used devices in this segment are KESS 3 and AUTOTUNER. I am looking for a device and provider that covers as many car brands and models as possible. Would KESS 3 be a good choice for a beginner trying to establish a business in this field (chip tuning, EGR on/off, DPF on/off, etc.)?

Thank you for your answers and opinions.
Kind regards.
