Your first day in ECU tuning. What it is, what you need, and your first read. No jargon, no gatekeeping, no recycled YouTube content. Just the bare basics taught properly so you know what you’re actually doing before you ever plug a tool into a car. Covers: what an ECU does, what a map is, the language you need to know, the kit you actually need to start, your first read walkthrough, and the safety stuff nobody talks about. Built for absolute beginners. 💪🏼🔧
